ew Zealand’s productive irrigated agriculture is a key part of its national economy and helps make it a top global dairy exporter. Anyone who has visited New Zealand’s irrigated farms also knows that New Zealand farmers are innovative and are always looking for cost-effective ways to improve their operations. I am pleased to be launching a new online New Zealand edition of Irrigation Leader to help strengthen the connections— personal, commercial, and technological—between U.S. and New Zealand irrigated ag. Elizabeth Soal, the former chief executive of Irrigation New Zealand, will be serving as a contributing editor, helping us to identify the most essential stories and technologies to highlight.

Our inaugural cover interview is with Gary Kelliher, a member of the Otago Regional Council who is also a farmer and has served in leadership roles in a local irrigation scheme and a catchment-wide strategy group. Mr. Kelliher tells us about his efforts to help resolve the persistent disagreements in the Otago region about how to manage water in the Manuherikia River catchment.

We also bring you several stories that highlight the excellent work that is being done in California’s Imperial Valley, one of the United States’ leading producers of winter produce.

We speak with Henry Martinez, the general manager of the Imperial Irrigation District (IID); IID zanjero Jeff Dollente; and Public Information Officer Robert Schettler.

Next, we speak with Peter Moller, Rubicon Water’s U.S. business development manager, about the company’s U.S. launch of its FarmConnect on-farm irrigation solution and with two U.S. farmers who are already using it.

point. We hear more about this attractive new product in our interview with Aimee Davis and Ken Quandt.

UPL provides an array of aquatic chemicals to help irrigation districts keep their conveyance structures clean. In our interview with Jeremy Slade, UPL’s U.S. business lead for aquatics, we hear more about the company’s products and customer service.

A column by Scott Cameron, the former acting assistant secretary for policy, management, and budget at the U.S. Department of the Interior and a former principal with the National Invasive Species Council, lays out a blueprint for a holistic approach to ecological sustainability.

We also feature interviews with individuals from three companies whose products may be of special interest to New Zealand readers: Paul Meeks of Worthington Products, whose booms helped avoid the overtopping of New Zealand’s Matahina Dam; Erik Tribelhorn of Agri-Inject, which enables the injection of fertilizer and chemicals through center-pivot systems; and Joel Irving and Chris Gargan of International Water Screens.

The irrigated ag communities in New Zealand and the United States have much to teach each other and many opportunities for each other’s business. I am proud to further that important interchange by launching this New Zealand issue of Irrigation Leader. I look forward to working with Elizabeth Soal, with all our other New Zealand friends, and with the many new friends we are sure to make in years to come.

Regional Councilor Gary Kelliher: Managing Water Use in the Otago Region

ew Zealand’s Otago region produces top-quality fruit, wines, crops, and livestock, and to do that, it needs water. In recent years, there have been persistent disagreements between the central government, the regional council, environmental interests, and community members about how to manage water in the catchment. Points of contention include how to distribute stored water, how to pay for water infrastructure, and what levels of flow must be preserved in the rivers. Gary Kelliher has addressed these issues from many angles. Himself a farmer, he has also served as the chair of an irrigation scheme and the deputy chair of an independent, catchment-wide strategy group, and he is currently a member of the Otago Regional Council (ORC). In this interview, he tells us about the many interests on the river and how they can find win-win solutions to their problems.

Gary Kelliher: I’m a fourth-generation farmer. I initially trained as an engineer. I have lived in New Zealand most of my life, other than 5 years in Ireland. My family operates other businesses as well, both inside and outside the farm.

I got involved in water at quite a young age, having been brought up with it. I have been involved in the politics and

management of water since we came back from Ireland and began farming on our own account in 2003.

Irrigation Leader: What kind of farming do you do?

Gary Kelliher: We are sheep and deer farmers. We have Romney sheep and red deer. We run some cattle as well, but we like deer, and they are suited to our area. We also have a quarrying business on the farm. We live close to one of the larger towns in our region, Alexandra. We’re surrounded by livestock blocks, horticulture, and a mixture of land use.

Irrigation Leader: Please tell us about your area and the most common crops and livestock there.

Gary Kelliher: We’re located in a mountainous range with productive valley floors. Traditionally, we’ve had finer-wooltype sheep and cattle run on our hill country and in our lower valley floor lands. There is a lot of horticulture and viticulture in our region and in the lower end of the valley; as you go further up the catchment, it gets too high and cold for those activities. Our land use hasn’t seen major changes or huge increases of intensity up until this point—dairying is the more intense form of farming in New Zealand, and there irrigationleadermagazine.com

Irrigation Leader: Please tell us about your background.

are only about 15 dairy farms in the catchment that I live in.

There are about 650 farming properties that access water.

Our local town has become popular for retirement alongside its predominant background as an agriculture service center.

Irrigation Leader: Would you tell us about your role in water management?

Gary Kelliher: My perceptions about water management changed as we started the development of our farm. The future of an area like ours, which is incredibly dry, began to concern me. It has a hot summer climate and a dry, cold winter climate.

My property gets only 350 millimeters (13.8 inches) of rain per annum. I could see from an early point that involving the entire community in future water decisions was the way to move forward, but that has been a huge challenge.

In 2003, I became a director of Manuherikia Irrigation Scheme (MIS), the local irrigation scheme that our farm was on. The scheme covers 2,500 hectares (6,178 acres), and at the time, the scheme had about 250–300 shareholders. I suppose the board of directors wanted to see some younger blood sitting around the boardroom table. Serving as a director is generally a bit of a thankless task. The scheme had been managed well, but it tends to be the individuals who are passionate or interested in the industry who are prepared to make the time to serve on the board. Eventually, I ended up being chairman of the scheme.

I could see then that I needed to be looking outside the scheme and at the catchment as a whole. There are six irrigation schemes in the catchment. Four of those schemes, including MIS, are in one valley and share in the dam at the head of the valley. Across the catchment, approximately 10,000 hectares (24,710 acres) are irrigated under the schemes in our valley, and another 7,500 hectares (18,533 acres) are irrigated in the other valley that contributes to the catchment.

My concern with water in the wider region made me more and more concerned about the future, specifically our consents to take water, most of which are expiring in 2021. That deadline required us to rethink the future and look at alternative sources. The Manuherikia River, which the six schemes in our catchment take from, can have both low and high flows—it can flow up to 600 cubic meters per second (cumecs) in flood, which is about 21,189 cubic feet per second (cfs). The dam at the end of the catchment can augment low flows during dry periods. We have another massive river, the Clutha, at the bottom of the catchment, and it flows an average of 500 cumecs (17,657 cfs), but it’s sort of in the wrong place. We have a lot of water, but we need to identify the best sources and how best to use them.

I worked closely with Irrigation New Zealand, and MIS helped to develop a small new scheme that now has about 1,300 hectares (3,212 acres) of new irrigation at the lower end of the valley. We could have done a lot more. We do hold a balance of water available for that. irrigationleadermagazine.com

In around 2011–2012, the six schemes in the catchment established the Manuherikia Catchment Water Strategy Group (MCWSG), an all-inclusive strategy group for the catchment with an independent chair. I was deputy chair. It included all the segments of the community that wanted to take part. Working in that strategy group, I began to wonder whether I should stand for election as an ORC councilor. I was elected in 2013 and served a 3‑year stint. A well-known New Zealand politician stood for the same position in 2016 and beat me by five votes. I continued with my catchment work until I stood again and was reelected in 2019. This time around, I’m not involved as much with the catchment. I don’t hold an official position with the MCWSG today, but I interact with it closely as we work through the issues.

The MCWSG was a community group without an official status, but it did approximately NZ$2 million (US$1.4 million) worth of investigatory work over several years under our local council’s banner. However, we reached a point at which the six schemes needed our own entity for the catchment, and we established Manuherikia River Limited to eventually own and manage the infrastructure for all six schemes.

Irrigation Leader: So a scheme like MIS owns some of its own infrastructure and also uses other infrastructure that is owned in common with the other five schemes in the catchment?

Gary Kelliher: MIS owns its own intake and a canal system to deliver water to the properties. The scheme is moving toward more piped delivery on the peripheries, but it plans to continue using its canal system from the river. The four schemes in the valley share storage in the dam at the head of the catchment. The dam is owned by the scheme in the upper valley. The end preferred model would be for ownership to sit with all the schemes, because the dam plays a part in managing the river during dry seasons. Over a 10‑year period, we will have at least two seasons during which we have to heavily ration what we take out of the river and heavily rely on that storage.

Irrigation Leader: What were the main points of contention between the different schemes that led you to move toward whole-catchment management? Were they mainly related to water allocation or to the costs of infrastructure?

Gary Kelliher: Both. The schemes have historically been owned and operated separately, but since they share in the dam, there has always been a robust debate around where the water is most needed—in the upper valley or the lower valley—and how best to conserve the water in the dam. The lower valley has always pushed to conserve as much water as possible within the dam, and the upper valley tends to want to work the dam harder and lift the reliability that it created. In the lower valley, the reliability was needed September 2021 | IRRIGATION LEADER

the water users and environmental groups. The intention was give the MRG the ability to set the minimum flow. The ORC also established a technical advisory group so that the MRG could request technical and scientific information and make informed decisions. When, in the last few months, we saw the outcome of the MRG’s 3 years of work, it caused an uproar in the community, because it did not provide a narrow and detailed set of targets. The range it provided is outside what can be provided with the current dam. It’s an aspiration that is so high it’s not funny.

The reason that has occurred is that the ORC has long believed that our catchment needed a sort of gamechanging hit on the head to rectify the river. It turns out that the science is saying, “The river is in good health whether it’s at high flow or low flow, and the varying attributes of the river can all be provided for.” That doesn’t match with the ORC’s belief that an increase in flows will remove the risk of intensity and will better the river. Now, the water users have had to go public with the message that achieving higher flows will absolutely cripple the economy.

That has now become the debate, and it’s a real shame that it has ended up that way.

Irrigation Leader: What are the major remaining disagreements within the catchment?

Irrigation Leader: What are the next steps you are going to take?

Gary Kelliher: They mainly relate to the river level. We gathered a lot of information to try to understand what we could and should do, but that ended in 2017 or 2018, because until we were able to set a minimum flow, we could not decide how to rebuild the dam or know what reliability it could provide to the water users. We have worked to meet a voluntary flow target of 900 liters per second (31.8 cfs) at the bottom of the catchment.

After 2018, the ORC established a new group called the Manuherikia Reference Group (MRG) with an independent chair. This was another all-encompassing group that included

Gary Kelliher: The water users in the catchment have no faith that the council or environmental interests are using defensible science in their decisionmaking. The water users have done the science that you would expect the ORC itself to have done, and because of that, the water users feel that they are in a position to justify the low flows and to be able to show the community that it is in both the river’s and the community’s best interest to use their lower indication of a minimum flow of 1,100 litres per second (38.8 cfs).

New national planning requirements mean the ORC must prepare a new comprehensive land and water plan by 2023.

most by our horticultural water users. We needed to move past that and establish a common understanding, and that was done relatively easily. We hoped that by involving the environmental groups and the wider community in the MCWSG and giving them a better understanding of the system’s hydrology and how water users across the catchment manage the river, we would end up with a path forward.

The MCWSG is required to set a minimum flow for environmental protection at the bottom of the catchment.

There was already a minimum flow midway down the catchment. We also needed the minimum flow to establish certainty around what we could do with the dam, which is an earth-filled, concrete-faced dam constructed in the 1930s.

It has some spillway capacity issues related to requirements for greater flood flow capabilities. It has an enclosed glory hole spillway, so we were always going to have to construct a new overlay over the crest spillway at some point. The major questions for us were whether to build a new dam or whether to increase the height of the existing dam, and if so, by how much. We hoped that was well understood by all and that we could arrive at a close understanding of each other.

Unfortunately, the reality was totally the opposite.

Lake Dunstan on the Clutha River at the bottom of the catchment.

The ORC was planning to just get through a consultation phase with the community around the Manuherikia catchment and then wait until the new land and water plan was announced in 2023 for formal consultation and regulations.

The next steps are for the water users to work hard with the community to show the community that the water users’ model is the right way forward and that it works in everybody’s best interests and in the river’s best interests.

New Zealand’s current government has put out a national policy statement that establishes a hierarchy according to which the rivers must be managed. The health of waterways must now always come first; the health of people comes second; and other uses of water, such as economic uses, come third. That is an aspirational way to protect a river, but I haven’t panicked too much about it, since if you don’t have the economic means to do what you’re hoping to do on level 1, it sort of ruins your ability to do anything on levels 2 or 3. I think the three need to work in parallel to come up with a sensible outcome.

Irrigation Leader: What are the other top issues of MIS and the other schemes?

Gary Kelliher: The water users have always proven with how they’ve managed the river that they are conservationists. My children grew up swimming in the river, I did too, and my father did before that. We’re protective of our rivers, so we suffer continually because of the perception that water users are the pillagers of the river. That makes us feel defensive, because we all live in this community.

We own and manage our infrastructure, and we will continue to manage it. By grouping together, we’ll be able to have farmers making decisions on infrastructure that normally would be managed by a municipal system with the town. The decisions about what standard of dam we will build and to what height we’ll build it are well advanced, but having them under one umbrella and having the expertise of our engaged professional team irrigationleadermagazine.com

will be advantageous for the catchment. There will be environmental monitoring to a greater extent across the catchment, and the schemes will manage it. In our catchment, it is possible for there to be an absolute win-win for everybody. Everyone can have what they would like to have within our catchment, whether it’s safe swimming, habitat for fisheries, or water use.

Irrigation Leader: Was there anything else you wanted to discuss that we haven’t touched on yet?

Gary Kelliher: There is an urban-versus-rural divide developing in New Zealand. Our central government, our regional governments, and to some extent our local government seem to be almost opposed to agriculture and horticulture. New Zealand agriculture provides produce to the world and provides a great tourism experience, and we are proud of our clean, green image. Yet we have an environmental lobby that is now quite influential in our central and regional governments and is costing the community, especially the water users and the irrigators, massively. They are experiencing a lot of stresses and uncertainties. We need long-term water consents to provide certainty and enable investment, and we’re really battling to get those. Local councils can’t upgrade their infrastructure without long-term, bankable consents, but regional councils, which are the consenting authorities, don’t want to give the irrigation sector the long-term consent it needs to upgrade the structure. We need to get past that. IL Gary Kelliher is a New Zealand farmer and an elected member of the Otago Regional Council. He can be contacted at gary.kelliher@orc.govt.nz.

Henry Martinez of the Imperial Irrigation District: Supporting Agriculture and Solving Problems

An IID vehicle stands next to a gate on the Eucalyptus Canal.

T

he Imperial Irrigation District (IID) has been providing water and energy services to inland Southern California for 110 years. A top user of Colorado River water and a top agricultural producer, it faces many of the same issues as other arid-region irrigation districts: drought, water supply, and infrastructure maintenance. However, it also must deal with the unique challenges related to the dropping water levels in the highly saline Salton Sea, including air pollution caused when wind stirs up the salty soil in the exposed lakebed, or playa. In this interview, IID General Manager Henry Martinez tells us about the district’s impressive services, the productive agriculture and large economy it supports, and how it is addressing the challenges of the Salton Sea.

Henry Martinez: I have been in the utility business for over 45 years. I have worked for large public and private utilities in both the water and energy departments. I came to IID a little

12 | IRRIGATION LEADER | September 2021

Irrigation Leader: Please tell us about IID’s history and current services.

Henry Martinez: The district celebrated 110 years of existence on July 25, 2021. It was formed to provide water services for Imperial County. Later, we became a public power provider, extending energy services into the eastern Coachella Valley and into the Riverside County area. We don’t provide water services in the Coachella Valley, since it has its own district, but we provide energy. We provide electricity to 155,000 electric meters and irrigate about half a million acres of crops, serving upward of 5,200 farm accounts.

over 3 years ago as an energy manager. At the time I arrived, the idea was that I would run the energy department as part of the district’s services for customers. I became the general manager of IID when my boss Kevin Kelley retired. I will have been general manager for 3 years at the end of 2021.

A gate on IID’s Trifolium Canal.

Henry Martinez: Grass and hay are among the highest ones, but we have a whole list of crops, including large field crops, such as alfalfa, Bermuda grass, kleingrass, Sudan grass, sugar beets, and wheat; and garden crops, such as broccoli, carrots, lemons, lettuce, mixed citrus, mixed vegetables, onions, spinach, sweet corn, and plenty more.

Irrigation Leader: What are the district’s top issues today?

Henry Martinez: Our only source of water is the Colorado River, and we have contracts with the federal government to receive water from it. We have one of the oldest and most senior rights on the Colorado. As you’ve been reading over the last 20 years, there has been a continuous drought in the Colorado basin, leading the storage in Lake Mead and Lake Powell to decline. At this point, we’re looking at how the hydrology will develop in the future and asking what effects it will have on our water supply and our water transfers to San Diego and the Coachella Valley. Discussions are occurring with the rightsholders on the Colorado River and the Bureau of Reclamation about the long-term forecast and what decisions we may have to make over the next couple of years if the shortage continues. Our senior rights give us a good amount of security, but water rights can only get us so far if there’s no water available, which is our greater concern.

This makes us cognizant of water use and has led us to make major efforts to conserve water in the irrigation arena. We incentivize farmers to use water more efficiently for their crops by compensating them for the water that is conserved.

Another issue is the Salton Sea. The Salton Sea has been affected by the drought and by changes in water use and conservation. Irrigation has accelerated the decline of the irrigationleadermagazine.com

water level in the Salton Sea, which is already declining due to evaporation. The rate of evaporation now exceeds inflows.

That results in greater exposure of the playa surrounding the Salton Sea, particularly in its southern part. Soil that was formerly covered with water is now exposed to the open air, and coupled with our wind conditions, we end up with air quality concerns. Further, the sea itself is highly saline, which raises questions about whether it is sustainable for wildlife habitat and fisheries.

On the energy side, one issue is that our 99‑year agreement to serve the Coachella Valley expires in 2033.

When the contract ends, it opens the door for other energy providers to step in. There have also been proposals in the California Legislature for representatives from the Coachella Valley to be added to IID’s board. That has become a major concern for us. We’re currently following a bill that was introduced by Assembly Member Chad Mayes, who represents a portion of Coachella Valley in the Palm Springs area, that proposes adding one additional ex officio member to our board. Also, the bill includes a provision for an analysis of how best to secure the future of energy service in the Coachella Valley after the current contract ends.

On the positive side, we’ve seen an interest in lithium development and in the development of additional geothermal energy in our service territory. The California Public Utilities Commission approved the procurement of 1,000 megawatts of new geothermal energy. That will open a lot of opportunities for geothermal development on land that the district owns. It was also recently announced that General Motors is partnering with a local developer, Control Thermal Resources, to develop lithium hydroxide in the Imperial Valley as a raw mineral for storage batteries. We September 2021 | IRRIGATION LEADER

expect major investments in the valley that will change the whole landscape of labor and infrastructure in the region.

Irrigation Leader: Would you tell us about the conservation efforts you are carrying out?

Henry Martinez: In 2015, we set up a program to incentivize farmers to invest in more elaborate systems, such as sprinklers, pumpback systems, and recovery systems, in order to minimize their use of water while maintaining the efficiency of their crop production. By putting significant effort and money into the programs, the district has been able to conserve quite a bit of water that would otherwise have been applied to the fields and then ended up as runoff to the Salton Sea. Again, that is a double-edged sword, because it reduces the already low inflows to the Salton Sea. This year, we authorized more funding to compensate the farmers for the conservation of water. We use the water that

our board decided not to participate in the conservation program. The DCP expires in 2026, so there has been an accelerated effort to begin addressing the provisions that may have to be implemented to maintain critical water availability for those who contract with the federal government for water.

Discussions on those issues have already started; we cannot wait until 2026 to start formulating plans.

Irrigation Leader: What is your message to other water users who depend on the Colorado River?

Henry Martinez: One of our mantras is that the Salton Sea is linked to the Colorado River. Whenever decisions are made regarding water use, water elevations, water deliveries, conservation plans, and regulations on water availability, we must keep in mind their effects on the Salton Sea and the risk that they will cause it to deteriorate further. Because of the Salton Sea’s relatively remote location, most people do not know about it and its environmental problems. We live in this area; we experience and see the conditions here. Our basic message is, “Don’t forget the Salton Sea when you are making plans for the allocation of Colorado River water resources.” We must address this issue concurrently with the allocation of Colorado River water.

Irrigation Leader: Are there efforts underway to reverse the decline in the Salton Sea’s water level or to address its salinity?

is conserved for transfers to urban areas. We also work with the Metropolitan Water District of Southern California to store some of that water in its system or behind Hoover Dam. Those partnership efforts help ensure that water is not wasted. Crop production has been maintained at the same level as before or higher, and the farming community continues to be healthy.

We’re also seeing the evolution of solar fields. We have excellent conditions here for solar energy production, and there is a trend of retiring farmland and converting it into solar panel farms. That indirectly conserves water, too. The downside is that the agricultural production of our area is reduced.

You may recall that in 2019, the federal government and the Colorado River contractors from the seven states of the Colorado basin signed the Drought Contingency Plan (DCP). IID did not participate in that agreement. The main reason we did not participate is that the compact did not acknowledge the detrimental effects it would have on the Salton Sea. Because that was not recognized in the agreement,

Henry Martinez: After a certain level of funding, the State of California has a responsibility to address these issues.

Secretary Wade Crowfoot of the California Natural Resources Agency has taken a leadership role in seeking state and federal funding. IID also advocates for federal funding to address the problems of the Salton Sea. There are also projects that have begun addressing those environmental concerns on a smaller, local scale. One project that broke ground early in 2021 is the Spatial Conservation Habitat Program. Its purpose is to create a habitat for wildlife and mitigate dust emissions through the shallow flooding of certain areas of exposed playa. We have worked with the State of California on other programs to reduce emissions and air pollution by treating parts of the playa with vegetation and furrowing to minimize the air quality problems that arise when high winds come across the sea.

There’s a lot more to do regarding salinity and other water quality issues. The state is evaluating proposals, including proposals to import water from the Sea of Cortez or the Pacific Ocean. The state works with the University of California, Santa Cruz, to determine whether the proposals are feasible ways to add water to the sea to stabilize it or improve its quality. There’s also a proposal to create what is called a perimeter lake. The perimeter lake would push the water toward the shoreline and create a smaller, more saline body of water in the center of the sea itself. The idea is to cover the shoreline by creating berms inside the sea, thus

reducing air pollution issues while maintaining the shoreline in a condition that is more ecologically and environmentally usable for wildlife and recreation. At this point, the State of California bears the responsibility for coming up with a solution for the Salton Sea. A large part of the problem is simply based on water quantity. Between drought and evaporation, water is rare. Solving this problem will cost quite a bit, but we need to fundamentally address the environmental problems of the sea.

Irrigation Leader: What is your message to Congress?

Henry Martinez: Congress and the federal government own property on the shoreline and the footprint of the Salton Sea. IID, the State of California, and various tribes also own land at the Salton Sea. We all have a responsibility as landowners to deal with its issues. Our long-standing concern has been that the federal government has been somewhat passive about contributing to a solution for the Salton Sea. Recently, we have had good support from Congressman Raul Ruiz and Congressman Juan Vargas, both of whom have introduced bills in Congress to provide funding to address the Salton Sea’s issues. However, those bills must be passed by both the House and the Senate and ultimately be signed by the president. They have a long way to go, but there is finally some movement in Washington, DC, to address these issues. Senator Dianne Feinstein has been tracking this issue for quite some time, and now, Senator Alex Padilla has also started paying more attention to the situation here. Congressman Raúl Grijalva from Arizona is the chair of the House Committee on Natural Resources and has held hearings regarding the Salton Sea. We had the first congressional hearing in 23 years in September 2020. On a positive note, we’ve seen more activity in the last 2 years to address the Salton Sea than we’ve seen in the past. We hope to see that attention and interest on the part of Congress continue.

Elected officials in San Francisco and Sacramento will also continue addressing this issue, despite those efforts being dormant for quite some time.

Irrigation Leader: What is your vision for the future of IID? Henry Martinez: My vision is to continue to maintain the flow of water into our district, which is one of the most productive irrigation districts in the United States. We want to maintain that leadership position and to maintain the productivity of the land, which has been built over the last 110 years. One thing that will require is being smart with water use. On the energy side, there have been huge changes in the electric business. It is getting more complicated to run an electric utility, particularly with all the changing policies and incentives in California, such as the renewable energy standards and the accelerating retirement of older gas- and coal-fired generation plants. irrigationleadermagazine.com

Another goal we have is to introduce new technology into our systems to make them more resilient, effective, and efficient and to keep our rates as low as possible. That is particularly important here in the Imperial Valley, because air conditioning is a necessity. Temperatures frequently reach 115 or 120 degrees during the summer and do not cool down in the evening. Energy costs can be a big burden for our customers, particularly given the unemployment rate in the county, which is one of the highest in the United States.

To continue to provide our critical services, we need the guidance of the board, and we will need to make intelligent investments, to pay attention to the basics of running the district efficiently, and to make the right decisions on a timely basis. Our services are necessary to maintain the valley’s economy and the livelihood of our customers. Our operations also need to be effective and sustainable for the long term. The district’s objectives are to be a major contributor to the economy of our service territory and to supply modern services to our water and energy customers.

Irrigation Leader: Is there anything else you would like to add?

Henry Martinez: We appreciate the work of our agricultural community and how it is stepping up through on-farm water conservation and efficiency programs. The farmers are not sacrificing the productivity of the land just to conserve water. We are sustaining or increasing the level of production relative to the previous irrigation methodologies.

Conservation doesn’t mean you don’t plant anything and fallow the land. We are working to be sustainable. IL

Why Zanjeros Are Fundamental to the Imperial Irrigation District’s Operations

An IID zanjero operates a manual gate on the North Date Canal.

T

he Imperial Irrigation District (IID) serves half a million acres of highly productive farmland in the Imperial Valley of Southern California with Colorado River water. Its massive water distribution system includes major canals and check structures that are operated automatically and remotely, but also thousands of field-level turnouts that must be manipulated by hand by the district’s zanjeros, or ditch riders. In this interview, Jeff Dollente, a zanjero for IID, and Robert Schettler, IID’s public information officer, tell us about the essential job zanjeros perform to deliver water safely to the district’s customers.

Jeff Dollente: As general background, water flows into IID’s system 24 hours a day, 7 days a week, mainly by gravity. We go up and down the ditch banks constantly, managing this water so that it goes to where it needs to go. We deliver and cut back water every day. Customers order the water the day before they need it. Then we get our shipment for the day and have to deliver it to the various fields and farmers.

Irrigation Leader: Mr. Dollente, please tell us how you came to be in your current position.

Jeff Dollente: I started at IID right out of high school and have been here since 1985.

Jeff Dollente: Each field has a delivery gate that we have to monitor to complete the order. We also have to adjust check structures to keep the ponds up and maintain pressure on the gates. The water that arrived today in the valley was ordered 3 days ago. Water is constantly moving, and it goes up and down.

Irrigation Leader: Would you tell us what a zanjero is, what your duties are, and how they differ from those of ditch riders elsewhere?

Irrigation Leader: Would you describe the size of IID’s delivery system and tell us how many gates or points of delivery there are? irrigationleadermagazine.com

Irrigation Leader: What is involved in making sure that water gets delivered where it needs to go? Does that involve manipulating manual gates?

Robert Schettler: We irrigate nearly half a million acres of farmland, some of the most productive in the nation.

Farmers grow every month of the year here. Summer crops include Sudan grass and alfalfa. In the winter, the Imperial Valley supplies 75 percent of the nation’s winter vegetable crop. This is possible because of the sunshine, but also because of the availability of water.

Our water comes from the Colorado River. It is stopped by structures like Hoover Dam and eventually gets to Imperial Dam, which is owned by the federal government but operated and maintained by IID. After Imperial Dam, the water is cleaned in a desilting basin, since there’s a lot of silt, sand, and sediment, and then goes into our canals.

The desilting basin is just north of Yuma, Arizona, but that’s 82 miles away from where we actually deliver water.

The water flows into the Imperial Valley, where we have major structures, and it goes through some power plants and generates electricity. Then it goes into the All-American Canal, which runs parallel to the U.S.-Mexico border. Once it finally hits the Imperial Valley, there are three major arteries: one on the east side of the valley, one in the middle, and one on the west.

On the larger level, coming from the dam and hitting the east highline, the gates are huge structures that are operated mechanically from our water control center. One of the questions that often comes up is why the system can’t be run all electronically. First, it’s just too vast. We have about 6,000 square miles of surface area that we have to get to on a daily basis. That includes plenty of big canals, laterals, and farm headgates. We have thousands of gates at the field level—perhaps 4,000–5,000. These structures are operated by our zanjeros, many by hand.

After the headgate, the water is the farmer’s responsibility.

It’s an intricate system that is fluctuating all the time.

There could be more water in one canal on the east side and more water needed on the west side, and our guys will have to make the adjustments.

Irrigation Leader: How has your job changed over the years as IID has modernized its system?

Jeff Dollente: Back when I started, water could only be ordered in 24–hour increments. We have now added the option of running water in 12-hour increments to better serve farmers.

Jeff Dollente: I guess trying keeping the customers happy and keeping them on order for the day. Cutting the water back without waste is also a challenge, although since my route has three reservoirs, it never has any water spilling out of it.

Robert Schettler: What Jeff is referring to are operational reservoirs. Water levels in the canals can fluctuate, so we use the operational reservoirs to hold some of the water for a little while and then turn it back in the system when it is needed so that it doesn’t go to waste. The levels in those operational reservoirs go up and down every day.

One of IID’s larger issues is that we don’t have major reservoirs of our own. Under the current rules and regulations at Hoover Dam, IID is limited to a set amount of storage there.

IID is the largest user-contractor of Colorado River water, and everybody looks to us in times of drought. The district is doing what it can as part of the quantification settlement agreement of 2003. IID has conserved almost 7 million acre-feet of water since 2003 for urban area use.

California itself only gets 4.4 million acre-feet a year. It’s guys like Jeff who make it happen.

Irrigation Leader: What are the top skills of a successful zanjero, and how do you learn them?

Jeff Dollente: Measuring water. You have to run the control checks successfully; if you let the water drop out, you can’t deliver it. It takes a little time to learn that.

Robert Schettler: In order to do their jobs well, our zanjeros have to maintain constant contact with the people they are serving, whether they are the landowner themselves, tenant farmers, or the irrigators who are in the field receiving the water. Everybody on Jeff ’s run knows his cell phone number, and they’re in constant contact. I believe that helps a lot.

Jeff Dollente: The customers are constantly changing their orders. If they finish irrigating early, they let you know—it doesn’t work out exactly 24 hours every time. We have guys working around the clock for our customers to reach out to.

ubicon Water’s technology helps manage 3.7 million acres of irrigated land. With thousands of miles of canals modernized and more than 35,000 automated control gates and meters sold, Rubicon’s innovative hardware and software is improving the efficiency and productivity of irrigated agriculture worldwide. One groundbreaking example is Rubicon’s FarmConnect solution, which leverages from technologies within Rubicon’s proven irrigation district solutions to provide individual farmers with precise, high-efficiency surface and furrow irrigation solutions. In this interview, Rubicon Business Development Manager Peter Moller tells us about the development and launch of the FarmConnect solution.

Irrigation Leader: Please tell us about your background and how you came to be in your current position.

Peter Moller: I’ve been working with Rubicon Water since 2010. Most of Rubicon’s prior business dealt directly with irrigation districts supplying canal automation, but my involvement began as I was asked by the directors to launch a new internal business unit to enter the market for on-farm automation technology for the application of water to farmer’s individual fields.

Our focus is assisting farmers to transform their flood irrigation systems by providing them with technology that enables them to apply the right quantity of water to crops when and where it is needed.

The initial step was to identify a solution for transforming traditional flood irrigation, which typically had an application efficiency of 50–60 percent, into a high-performance surface irrigation system that delivers application efficiency of 85 percent or better. We saw an opportunity to adapt Rubicon’s irrigation district technology to apply the science on farm. This was the beginning of what is now FarmConnect.

In the early stages, we had to understand the limitations of these manually operated flood irrigation systems and try to envisage a solution that could enhance performance without the barriers for uptake. After 18 months of product development, I was responsible for taking the solution to the commercial market.

We focused on an area within Australia’s Murray Darling basin and launched the solution to a group consisting predominantly of dairy farmers who grew pasture for dairy cows, corn for silage or grain, and alfalfa for feedstock. In 2015, we worked to automate furrow irrigation for the cotton industry, which grows crops on raised beds. For the first 7 years, our focus was on Shepparton, Victoria, where we achieved some impressive results for irrigators, including doubling their production per amount of water applied. With the production of corn for silage, we’ve been able to go from 2.6 tons per acre-foot of dry matter to 5.4 tons. Studies have revealed that irrigators are growing twice as much dry matter with the same volume of water. This is particularly relevant during the periods when we are at risk of water insecurity and are under restrictions on water use.

Following the successful outcomes for Australian irrigators, we soon implemented pilots of the on-farm automation control sensing technology in California, China, Italy, and Spain. In 2017, I was asked to take on a role within the U.S. business as national sales manager and business development manager, working with our account managers to focus on the customer relations side of Rubicon, specifically in relation to irrigation districts. Now, as we formally launch Rubicon’s FarmConnect solution in the U.S. market, our focus will be on irrigators who are currently using gravity flood irrigation systems and have a need to improve their application efficiency, reduce labor costs, and increase productivity.

Irrigation Leader: What is the FarmConnect solution, and how does it fit into the broader array of Rubicon products?

Peter Moller: Rubicon is working to increase agricultural water use efficiency from source to crop. We see a real opportunity to use hardware, software, connected devices, radio frequency (RF) systems, and data analytics to provide enormous water savings, and these opportunities have already been largely realized off farm. We work to improve the application efficiency of the surface irrigation system and to improve scheduling so that the right amount of water is delivered at the right time to the crop.

When it comes to the application of water to crops, we want to help transform flood irrigation. We know that the majority of the world’s crops are presently irrigated using flood irrigation, which consumes little energy but also has a reputation for low application efficiency. If this application efficiency can be improved, we will have a low-energy, high-efficiency solution. By using technology to improve precision, we have improved the application efficiency of surface irrigation from 50–60 percent to 85 or better, in many cases with zero input energy requirements. We’ve been able to demonstrate results like these in Australia and have had independent reviews by universities to measure and define them. In the United States, we’ve been working with the University of California, Davis (UC Davis), and its researchers and extension officers. One of the projects that we worked on at its research station in Southern California was able to demonstrate that with gravity-fed surface irrigation, we can achieve 85 percent application efficiency or better by using the measurement and autonomous control technologies that Rubicon has been developing for 25 years with irrigation districts. Modernized networks provide precise, on-demand water supplies that give irrigators the tools and flexibility to apply the right amount of water at the right times.

FarmConnect empowers farmers to harness the benefits of precision surface irrigation, including savings in energy and labor costs, improved water use efficiency, and enhanced yields.

Irrigation Leader: Is FarmConnect a combination of both hardware and software? irrigationleadermagazine.com

Peter Moller: Yes. FarmConnect uses smart sensors to measure and help predict what is going on in the field and provides farmers with data at their fingertips. The hardware component involves smart valves and gates that automate the water application process. Sophisticated software assists farmers with irrigation scheduling decisions so that they can precisely manage each irrigation event. For example, soil moisture monitors track exactly how much water the crop is using and how deep the water is infiltrating in the root zone of the crop. This helps farmers ensure that there’s no unintended deep drainage. FarmConnect uses precise gate and valve devices that are actuated to open, close, and regulate at the desired times, allowing precise volumes of water to be applied at high flow rates. These devices include overshot gates in on-farm canal systems and 16‑inch valves, such as alfalfa valves, in pipe systems. Rubicon also supplies accurate flow meters and controllers that maintain constant flow rates set by the farmer. The flows are kept constant despite canal or on-farm water level fluctuations. This allows for the precise management of applied volumes on a time basis. The technology also incorporates in-field sensors that can measure the rate of advance and infiltration as water is applied to each field so that the application flow rate and duration can be optimized at various stages of crop growth.

Using this technology, we have been able to make significant advances in the application efficiency of surface irrigation, making it highly competitive from an application-efficiency perspective and compelling from an energy use/operating cost perspective. The hardware, the radio networks, and the software are all provided as a cohesive, integrated solution that makes FarmConnect both easy to use and reliable.

The platform provides data analytics to help predict when the next irrigation should be scheduled, to determine how much water to apply to each field, and to run the system autonomously without human intervention. Flood irrigation has historically been a highly manual activity. We are reducing its labor component at a time when labor costs are increasing, particularly in California. As irrigators are retiring, there aren’t many skilled workers coming in to replace them.

Irrigation Leader: Is each FarmConnect system customized to a farmer’s property and operations?

Peter Moller: Yes. We have standard product components: automatic gates and valves in a number of different sizes to accommodate different on-farm application systems, water level sensors, wetting advance sensors, and flow control products to provide precise volumes of water. The solution uses a lot of technology that Rubicon has developed over decades with irrigation districts: all the components that open and close gates, the actuators, the motors, the gearboxes, the cable drive systems, the RF systems, and the software for control. We’ve taken the proven methodologies we use to automate irrigation districts and fine-tuned them for on-farm irrigation systems. We made the system smaller to handle September 2021 | IRRIGATION LEADER

lower flows than irrigation districts do and adapted the hardware and software to be more suitable for irrigated farms.

The software is customized with a detailed map of where the devices are located, what they’re connected to, what they attribute to, and whether they’re controlled or monitored.

Irrigation Leader: Do you produce your own probes?

Peter Moller: We use a select range of third-party probes that we trust from experience to provide accuracy, reliability, and value for money. We’ve focused on the integration of these market-leading probes into a system that is easy and accessible for farmers and integrates into their broader onfarm operations. We have developed radio nodes that can be connected to a whole range of environmental sensors or monitoring sensors. For example, farmers can buy our RF node and then connect other vendors’ soil probes so that they have a single platform for control, automation, and sensing. To complement soil probes, Rubicon has developed an all-in-one microclimatic weather station to provided localized weather data that determine real-time evapotranspiration and climatic conditions and provide valuable insights into irrigation scheduling and prediction.

Irrigation Leader: Would you describe your pilot program with UC Davis and the Imperial Valley sugar beet industry?

20 | IRRIGATION LEADER | September 2021

Irrigation Leader: Is your current launch focused on pilot projects only, or are you selling the solution to interested customers as well?

Peter Moller: In the next couple of months, we’ll be fully stocked for projects in the United States. We’re focusing on a number of projects with irrigators at a commercial level in the Central Valley of California and in Southern California. We also have opportunities in Utah: There’s a valley there where farmers are looking for automation and a water efficient surface irrigation system. We have interest, and there is a group of farms and projects that are already operational, some of which are being closely monitored by UC Davis and, in Utah, by Utah State University.

Irrigation Leader: What is the expected time required for return on investment for a standard farmer?

Peter Moller: We have proven that Rubicon’s on-farm products work commercially and operationally over the last 10 years, including in the Southern California desert, and that they deliver a return on investment within 3 years because of the water and labor savings and productivity increases they enable. That really does interest farmers and is convincing many to take the step of implementing this technology.

Also, the barriers to entry are being reduced by federal and state grants for on-farm water use efficiency. There is a range of grants that can help fund these improvements and reduce farmers’ costs by up to half. We encourage any farmer planning to modernize their flood irrigation systems to explore this option to achieve a high-performance surface irrigation system with minimal energy costs. IL

Peter Moller: The irrigation researchers at UC Davis were familiar with the results we were achieving in Australia with modernized on-farm systems, including the work we’ve done with Australian universities, and were interested in using Rubicon’s technology for local research. We installed an automatic gate at the University of California Cooperative Extension Desert Research and Extension Center in Holtville in the Imperial Valley Irrigation District, where it’s been operating for the last 10 years with different crops and different trials.

In early 2019, I was approached by UC Davis to talk to the Imperial Valley sugar beet industry’s research committee, which was deciding on its research priorities. The emerging challenge for the industry was that the cost of labor in California was significantly increasing and the value of water was also changing. Something needed to be done to provide security to the sugar beet industry. The research committee reached out to us, and we presented it a use case, facilitated by UC Davis, on what we had done with furrow irrigation in the cotton industry. Like cotton, sugar beets are grown on raised beds and are irrigated with over-the-bank manual siphons. Rubicon has proven that automating furrow irrigation is possible, and we were able to demonstrate the benefits that had been achieved in Australia. We felt that the same benefits could be provided on a broader scale.

After that meeting in February 2019, the research committee gave UC Davis the go-ahead for a trial at the research station. During 2020 and into 2021, UC Davis

grew a sugar beet crop; performed frequent measurements of water volumes, the advance rate of water down a bay, and the number of irrigations; and analyzed the performance of the trial. In March 2021, I saw a paper by Dr. Khaled Bali and Dr. Stephen Kafka of UC Davis that was produced with the results of that work and showed that they had achieved an application efficiency of 85 percent.

The project for 2021–2022 is scaling up the trial in partnership with commercial sugar beet growers. I will be meeting with a farmer in the Imperial Valley to put this in a commercial context and analyze the solution in a commercial production system and to see how it’s run by an irrigator, what the user experience is, and whether it can work on a commercial level in this industry.

Ronald Leimgruber: Using FarmConnect in the Imperial Valley

R

onald Leimgruber is a third-generation farmer in California’s Imperial Valley who uses a variety of irrigation methods to grow his crops. He has been using Rubicon’s technology for over 10 years.

Irrigation Leader: Please tell us about yourself and your farming operations.

Ronald Leimgruber: I’m a third-generation farmer. I started farming in the 1980s after graduating from college with a business degree. My grandparents and my dad were dairy, livestock, and crop farmers. We’ve diversified into produce crops, onions, carrots, alfalfa, and seed crops. We have about 2,022 acres.

Irrigation Leader: What are your main irrigation methods?

Ronald Leimgruber: We implement six different methods.

Predominantly, we do surface line border check irrigation, which is the predominant method in the Imperial Valley.

That means our fields are laser leveled to a precise slope and flooded from one end to the other. We also use drip irrigation; overhead linear move irrigation, which is similar to center-pivot irrigation but linear instead of circular; solidset irrigation, which uses 3‑inch dam lines to germinate our crops; level basin irrigation, where the ground is 100 percent level and we run water in for a fixed amount of time; and furrow irrigation, which is used for certain produce crops.

Irrigation Leader: Please tell us about your experience using Rubicon’s FarmConnect system.

Irrigation Leader: What are some of the benefits of automation and remote control for your operations?

to check on where the water is, because we have sensors out there. We get increased production, we get more uniformity of water application, we get water savings because we’re minimizing our tail water, and we get labor savings because we don’t have to pay the irrigator to monitor the water.

Irrigation Leader: More generally, what are the benefits of transforming flood irrigation using a technology like this?

Ronald Leimgruber: I’ve been using this system for 12 years now, and you have to apply larger volumes of water in shorter amounts of time. You try to be as efficient with your water as you can because the lower end of your field needs opportunity time for that water to infiltrate into the soil. If you get too much infiltration time, you get excessive water past your root zone. We need that in Imperial Valley soils, because every acre-foot of Colorado River water we apply contains 2,000 pounds of salt. The only way to keep our soils productive is to overirrigate our soils by about 10–15 percent so that we drive the water to our tile system, which takes the salts out to the Salton Sea and keeps our soil in balance.

With the Rubicon system, you have to be really careful that you keep that high level of water infiltration, but it’ll definitely save labor and water and increase production.

You need to do all three of those things to be profitable in farming nowadays. Your margins are so thin—all you get to work with is about 5 percent—and if I can increase that to 7 percent, that’s a big difference. IL

Ronald Leimgruber: The Rubicon system has two parts. The automatic gates help you control your water by sensing where it is opening and closing automatically. The smart connect part of it monitors the amount of water you’re putting in each basin and helps to minimize your tail water and runoff water.

In the Imperial Valley, because of the slopes of our ground, we have to saturate the lower end of the field as much as the upper end, so a certain amount of tail water is necessary, but we’re trying to minimize it as much as we can. One of the benefits of the FarmConnect system is that it allows us to monitor our water on each bay and the runoff water and to calibrate the difference to conserve water. We have plans to install two additional FarmConnect systems.

olton Russon, who runs a dairy farm and grows barley, corn, and hay in Tremonton, Utah, has recently started using a Rubicon FarmConnect system. In this interview, Mr. Russon tells us about the results he is seeing from the system.

Irrigation Leader: Please tell us about your background and your current farming operations.

Colton Russon: I work with my father-in-law on his dairy farm. We also grow barley, corn, and hay. Right now, we’ve split one field in half and have summer fallowed one half and are growing corn on the other. We’ve got about 50 acres total.

Irrigation Leader: Why did you purchase and install a FarmConnect system? What was the problem you were trying to solve?

Colton Russon: We had a bunch of small fields that were eroding into a nearby creek, so we laser leveled everything and changed the direction of the water flow. Our aim in that was to make our irrigation more efficient and to get the same results with less water. The State of Utah told us about Rubicon, so we decided to look into it. We got funding from the state to help us purchase and install an automated system, and we started using our Rubicon system just a couple of months ago.

PHOTOS COURTESY OF COLTON RUSSON.

Irrigation Leader: Are you primarily using furrow irrigation?

Colton Russon: We’re in the experimental stage of this process. Right now, we actually irrigate our corn by flooding it, rather than using furrow irrigation. We are trying to figure out what works best with the system. Next year, we’ll probably do what they call a pontoon—we’ll dig a 6‑inch trough in front of the blade valves and fill that up, then furrow the corn up to that little trough.

Irrigation Leader: What results are you seeing from this system?

let the water run all night long instead of having to go out and do it myself. Before, we were running siphon tubes, so I would have to be in the fields at 2:00 or 3:00 a.m. Now, we’ve got sensors out in the field that allow me to track everything.

A bunch of helpful information is now available, too. This system has made our irrigation faster. We have been able to go across the field more quickly; we’re gaining time every day.

Irrigation Leader: How could the dairy industry benefit commercially from using a system like FarmConnect to make its surface irrigation more efficient?

Colton Russon: The difference that we’ve noticed is that our irrigation has become more efficient, which is especially important given the current water situation in Utah. We can get across the fields faster with less erosion, hopefully giving the plants their exact water needs. I know that the sensors of the FarmConnect system will tell me when the plants need water. That way, we can raise better yield and better crops for dairy cows.

Irrigation Leader: Would you tell us about the experience of working with Rubicon?

Colton Russon: Rubicon was awesome. We ran into a few issues related to translating Rubicon’s original metric measurements into U.S. units, but the company was great and was able to figure that out; I didn’t even have to get involved. Rubicon staff have helped me figure out the system and how to do various things. The technical support has been great. The people have all been awesome in helping me get everything running and figure out better ways to be more efficient in watering the crop. IL

Aimee Davis and Ken Quandt: Making Meters Work Smarter and Harder at McCrometer

Aimee Davis describes the installation process for the McMag2000 in this still from McCrometer’s instructional video.

M

Irrigation Leader: Please tell us about your backgrounds and how you came to be in your current positions.

24 | IRRIGATION LEADER | September 2021

Aimee Davis: I am a senior product manager at McCrometer. I’ve been with the company for quite a long time. I started working with the company back in the year 2000. I’ve had varying roles in operations and quality management and eventually found myself in marketing and product management. In February 2021, I was promoted to senior product management.

Ken Quandt: I work in market development for McCrometer.

I’ve been with McCrometer almost 15 years now. I started out working for Great Plains Meter, which was the Midwest ag rep for McCrometer. Then I went on to work for McCrometer as a regional sales manager, worked in marketing for a while, and did a lot of government relations work. Now I’m back on the sales team, and I work with all the ag regional sales managers on special district projects, irrigationleadermagazine.com

cCrometer has long been a stalwart in the irrigation industry. Its innovative meter products allow irrigators to properly measure water efficiently and cost effectively. As new technologies and customer demands have emerged, McCrometer has continually innovated in order to keep providing water users with high-quality yet affordable products.

The company continues to do precisely that with its new mag meter products. In this interview, Senior Product Manager Aimee Davis and Market Development Manager Ken Quandt tell Irrigation Leader about why McCrometer developed the new mag meters, how it innovated to optimize them for customers’ needs, and the meters’ appeal to both irrigation and municipal water users.

irrigation districts, and conservation districts. I also develop grant proposals with some of our district partners.

Irrigation Leader: Please introduce the company and its product lines.

Aimee Davis: McCrometer was founded in 1955. The company first started out with our McPropeller meter, which was for the agriculture market. For a long time, we stayed in the agricultural market with quite a few different products. In 1985, we came out with the V-Cone meter, which allowed us to start playing in other markets, such as energy and industrial. Today, we are in all those markets as well as the municipal sector. We have varying ranges of product lines, but I’d group them into a few categories.

We have propeller, or mechanical, meters. We have electromagnetic meters, both full bore and insertion types.

We also have our differential pressure meters: our V-Cone and Wafer-Cone. And then we have accessories such as Connect and FlowConnect, which allow customers to get meter readings sent directly to a phone, desktop, or laptop through telemetry.

Irrigation Leader: Why did McCrometer develop the new McMag2000 meter, and how does it differ from your other mag meters?

Aimee Davis: We started seeing a trend of agricultural customers wanting meters with no moving parts. They also wanted something that was at price parity with what they were used to paying for propeller meters. However, the prices of most mag meters are quite a bit higher than those of propeller meters. Working with our research and development (R&D) team and a few others, and we tried to offer the farmers and irrigators an affordable, easy-toread meter with a similar look to the McPropeller. The new McMag2000 meter uses the same saddle as the McPropeller.

That makes it easy for customers who want to shift to mag meters to retrofit. They can buy a kit and easily build it in the field themselves. We have a YouTube video that shows them how to do it step by step.

We have a patent pending on the sensor. It has dual electrodes and takes the reading from the center of the flow column. That improves the signal distribution and ensures better accuracy. It’s a great little sensor. It has a modular design. To me, that’s really what makes it different, not only from our other mag meters but from the other mag meters in the marketplace. The modular design allows it to be fully serviceable in the field. Although it is modular, it still has no moving parts, just like other mag meters, meaning users need to do fewer repairs. One of the things that our customers love about the McPropeller is that they’re actually able to maintain them in the field, which reduces downtime.

This is the first mag meter that lets them do that. The sensor and converter can be easily replaced, and of course, irrigationleadermagazine.com

we have in-field batteries, so they can be replaced as well.

Another great thing that makes the McMag2000 different from any other meter is that it can partner with veins and flow straighteners. That drastically reduces straight-run requirements and eliminates the need to repipe customers’ systems when they switch to a different technology. We wanted to give customers a true, direct replacement for the McPropeller meter for when they were ready to make the jump to the mag technology.

A view of the new McMag2000.

Irrigation Leader: How did you keep the price of this meter down?

Aimee Davis: We built all of it in house, including the sensors and the electronics, and then we used the saddle we already use for the McPropeller. The converter housing is a different color, but otherwise it’s exactly like the housing for our McPropeller digital registers. Using the same housing and saddle as we do for other products allowed us to keep our costs down, and we pass that saving on to our customers. Ensuring price parity was a major motivator for the for the R&D team, which meant we had to figure out a way to take mag meter technology to the next level while keeping the cost low.

Irrigation Leader: In general, what are the advantages of mag meters over propeller meters, and why might current users of propeller meters want to upgrade?

Aimee Davis: Customers really want to get away from moving parts. The more moving parts there are, the more likely it is that an issue may arise. Mag meters have no moving parts at all—they just have electrodes sending the signal into the pipeline and a converter doing the correlation to determine the flow rate. They require less maintenance. However, when most mag meters do require maintenance, they have to be shipped back to the factory or taken to a certified service provider. The McMag2000 is the first mag meter that does not require that. It keeps downtime low, which was one of the things people liked about the McPropeller.

Ken Quandt: The other advantage to a meter like this is that it is easy to integrate into the irrigator’s system and to make it a sensor. It has the built-in ability to send a pulse signal into a pivot panel or a telemetry system so that users can make better use of the meter as a management tool. A lot of farmers want to integrate the meter into the pivot panel so that they can have a better handle on how much water they’re applying.

A meter like this has a built-in pulse-output technology that can be integrated into their systems much more easily.

Irrigation is getting more technologically advanced, and this helps farmers integrate meters into their systems.

Irrigation Leader: Would you tell us more about the retrofit process?

Aimee Davis: The retrofit is pretty quick and easy. I put together a YouTube video where I walk users through the process. The video is about 7 minutes long, and a user could probably get it done in less than 20 minutes, including the time it takes to stop and look at the instructions. The user has to take the bearing housing off the ell of the pipe that comes off the saddle, unscrew the bearing housing, screw in the sensor, and then plug the ethernet cable that connects in through the ell of the pipe into the sensor. Then, after a little mounting of the electronics, it’s good to go.

Ken Quandt: The modular design that Aimee mentioned is a new philosophy for a meter like this. Just the other night, I was talking to a landowner in Aurora, Nebraska, who has a mag meter from a competitor that he put in 5 years ago.

Now, it has failed on him, and he can’t repair it. If he had a meter like the McMag2000, he could replace the sensor or converter and he’d be back in business. Unfortunately, he doesn’t have that option—he has to replace the whole meter.

Aimee Davis: On our website and in our brochure, you can see the exploded diagram for the McMag2000’s modular design. You can also see the converter detached from the saddle, the U bolts, and the sensor. It’s got an ethernet cable.

Users can buy the sensor by itself or buy the kit, which includes the converter and the sensor. If a customer wanted to, they could even keep that on the shelf in case they experienced any issues down the road.

Irrigation Leader: Is this product appropriate for pretty much anybody who wants to measure flow in a pipe, or is there something that makes it particularly appropriate for agricultural users?

26 | IRRIGATION LEADER | September 2021

Ken Quandt: People always used to say that if someone was irrigating with good, clean groundwater, nothing was more efficient and economical than a McPropeller. But many people irrigate with dirty water rather than good, clean groundwater. There are surface water irrigation districts with sediment and vegetation in the water, which creates issues with mechanical meters, props, and bearing assemblies; this is a good meter for applications like that.

Irrigation Leader: Is there anything else you would like to add?

Aimee Davis: The other thing that was important when we were designing this product was durability. Customers have come to expect a robust product from us, and we’re happy that they do. We wanted to make sure that this had a long product life cycle, and it did so well in testing that we were able to offer a 5‑year warranty on it. That doesn’t just cover the batteries; it covers the converter, the sensor, and the hardware. It’s a complete, bumper-to-bumper guarantee for 5 years. I think that is important to customers making a purchase for a farm.

Ken Quandt: I like to describe this meter as a mag meter that fits in the footprint of a propeller meter. This creates a good opportunity for customers to upgrade from the mechanical propeller meters they have used in the past.

They don’t have to worry about taking out the veins they have from their propeller meters. Customers can calibrate the meters specifically to the veins that are already in the pipes. It’s a direct replacement for what they had before, and it’s much easier to integrate this meter into their existing system. IL Aimee Davis is a senior product manager at McCrometer.

Aimee Davis: We designed the McMag2000 with farmers in mind mostly because we saw the shift from the McPropeller, which is popular with irrigators. That’s not to say that we haven’t also sold them for some municipal applications as well.

We just recently extended the line sizes we offer. At launch, we offered options from 4 to 12 inches. Now we offer 14‑ and

16‑inch options for those surface water applications, which may be of interest for municipal users. We may also launch another configuration in addition to the saddle configuration.

I have some beta models of top-plate configurations out in the field; those will appeal to municipal users who like the top-plate configuration with our propeller meters and are interested in moving to mag meters without having to repipe their whole systems. Supplying additional configurations for this mag meter technology is something we’re focusing on.

UPL’s Products and Services for Irrigation and Canal Districts

UPL's CASCADE herbicide being applied.

U

PL is the fifth-largest agrochemical company in the world and provides an array of aquatic chemicals to help irrigation districts keep their conveyance structures clean. Not only does UPL manufacture some of the best-known aquatic herbicides in the irrigation business, it also delivers quality customer service. In this interview, UPL’s business lead for aquatics, Jeremy Slade, tells Irrigation Leader about his field of the business and changes in the industry.

Irrigation Leader: Please tell us about your background and how you came to be in your current position.

28 | IRRIGATION LEADER | September 2021

Irrigation Leader: Please tell our readers about UPL as a company.

Jeremy Slade: We’re the fifth-largest agrochemical company in the world, a ranking we reached a couple of years ago with irrigationleadermagazine.com

PHOTOS COURTESY OF UPL.

Jeremy Slade: I’ve been in the aquatic plant management industry for about 15 years. After college, my first real job was working as a research associate at Mississippi State University.

I was contracted by the U.S. Army Engineer Research and Development Center, where I evaluated herbicides and algaecides in controlled settings (i.e., mesocosms and growth chambers), supporting new product registrations with the U.S. Environmental Protection Agency (EPA) and developing new use patterns for existing registered herbicides and algaecides. I did that for about 3 years and

then moved to Florida, where I took a job at the Center for Aquatic Invasive Plants at the University of Florida.

There, I evaluated herbicide applications of various scales to support the operations of the Florida Fish and Wildlife Commission, which has one of the largest aquatic plant management programs in the country. A little over 10 years ago, I joined UPL as a territory sales manager for the southeastern United States. My territory spanned from Texas to Florida and up to Tennessee. In that capacity, I worked with commercial applicators and state and federal agencies to provide recommendations for their aquatic plant management operations. A little over 2 years ago, I took over as the business lead for the UPL aquatics division, where I manage a team of five territory managers and one field development manager.

Two of the territory managers I manage are primarily focused the irrigation canal business in the 15 western states.

the acquisition of Arysta LifeScience. UPL was founded in 1969 and today has a presence in more than 138 countries.

In the United States, we were previously known as UPI, but aligning with the global structure, we updated the name to UPL NA Inc. The NA stands for North America. The North American headquarters is located outside Philadelphia, Pennsylvania. Our focus is providing sustainable and customer-centric solutions. We offer a variety of products and services, primarily for agriculture, but we also have divisions that service specialty markets like golf courses, fumigation, biosolutions, seed treatment, and aquatics. The United States is the only country within UPL that has an aquatics division.

Irrigation Leader: How many folks work at UPL? Jeremy Slade: Globally, there are more than 10,000 employees. There are more than 300 UPL employees in North America.

Irrigation Leader: Please tell us about UPL’s canal herbicide portfolio.

Jeremy Slade: The irrigation canal portfolio isn’t broad, but it has had a significant effect on the irrigation canal market over the last 10 years. We have two primary brands, CASCADE and TETON, both of which are endothall based and provide excellent efficacy and longevity when used appropriately.

CASCADE is a potassium endothall formulation and is classified as a herbicide. TETON is the amine endothall formulation and is classified as an herbicide and an algaecide.

Both products come in various package sizes, have limited use restrictions, are easy to apply, and have versatile use patterns to control weeds in small to large systems. We also have two copper formulations, which most readers might not be familiar with: CURRENT and SYMMETRY. CURRENT is classified as an herbicide, and SYMMETRY is classified as an algaecide, and both products are chelated coppers with 8 percent elemental copper. Both can be used in conjunction with endothall-based products or independently. Most recently, we were granted EPA approval for a new product called TOP DECK. While the name is new, there are other products in the market with the same active ingredient, imazamox. We’re currently working on state registrations for this new product. Once all of those are received, it will be available for use in and around aquatic sites, such as laterals or bank work, for vegetation management, and in deep water canals prior to filling.

Irrigation Leader: Who are your main customers?

Jeremy Slade: Our customers include anyone who manages water, specifically nuisance plants and algae. Often, people think of exotic invasive plants as the main nuisances, but in the irrigation canal market, native plants can also create irrigationleadermagazine.com

problems for conveyance. UPL started by managing plants and algae in the lakes, ponds, reservoirs, and river markets, which is the field we typically call aquatics. The irrigation market is relatively new to us, but our customers include homeowners, commercial applicators, irrigation districts, municipalities, and state and federal agencies.

Irrigation Leader: How does UPL develop its markets?

Jeremy Slade: We look for markets and opportunities to provide solutions to customers who are dealing with water weeds and algae issues. We know that water is one of the most valuable resources we have, and we keep that in mind when we work with our customers, including irrigation districts, commercial applicators, agencies, universities, and homeowners. We work with all of them simultaneously to understand issues that occur in the field, and we try to leverage knowledge and experience to continually refine solutions and products.

For example, prior to the registration of CASCADE and TETON for use in the water conveyance systems of the 15 western states, there weren’t many options. At that time, there was a need for an effective, long-lasting, environmentally friendly solution to make water management easier. We believe both products have filled that niche. In most instances, irrigation districts have relatively short windows for their operations, so we’re looking for sciencebased recommendations to develop our markets and provide solutions to customers that they don’t typically have.

Irrigation Leader: What kind of results do your clients see from using UPL products?

Jeremy Slade: In short, efficacy and longevity. Our products have few restrictions and are easy to apply, and our many years of experience allow us to make strong, sound, sciencebased recommendations. As a result, our customers have become accustomed to getting the results they need to achieve. Those results are weed- and algae-free canals during the time of year during which they need deliver water to their customers. With less time needed for managing weeds and algae, irrigation managers and ditch tenders can focus on their other maintenance tasks. Our customers are happy with the products, which are efficacious and economical.

Irrigation Leader: What kind of technical support does UPL provide?

Jeremy Slade: One of the advantages of UPL is that all our territory managers have worked in the industry in various capacities. I’ve got a couple managers who worked as applicators; two of my managers and I did research in the field; one of my managers worked in distribution; and all of us have been in the plant management industry for many years now. Because of that, we have a strong September 2021 | IRRIGATION LEADER

| 29

knowledge base and experience that allow us to provide solid recommendations. When it comes to technical support in particular, we do have a technical development manager who works with the territory managers on any questions or issues that come up in the field.

If a customer isn’t getting the level of efficacy that they feel they should, we can provide sampling and analysis to identify the cause. Dye studies and herbicide residue analysis are two tools that we use to determine treatment regiments and correlate efficacy. Both of these aid us in making sure that plans are in place and work as a check to make sure treatments are hitting a concentration exposure time requirement. We want to understand the goals and objectives of the canal manager.

We also work with each irrigation district to provide a unique solution, because each system is unique. We want to make sure we tailor treatment regimens to specific systems to guarantee results. Sometimes, this requires adaptive management.

Because CASCADE and TETON are easy to apply, we can even make on-the-fly adjustments on the day of the treatment.

Our territory managers and field development manager are dedicated to working with each individual customer.

We also provide excellent customer service and regulatory support. We not only want to do a good job on the technical side, but we want to make sure the product is there on time, is clean, and looks good. We’re also committed to addressing any questions regarding National Pollutant Discharge Elimination System permits and ensuring that we’re following all regulatory guidelines.

Irrigation Leader: Does UPL have a unique payment delivery program that fits the budget cycles of irrigation districts?

Jeremy Slade: We’ve tried to make sure our purchasing programs for irrigation districts take advantage of preferred pricing early in the year to appeal to their boards of directors so that they can get the product prior to the start of the treatment season. From what we’ve seen, that is valuable to canal companies. They want to cover their product needs early in the season so that they can hit the ground running when it’s time to go.

Irrigation Leader: What is your message to irrigation districts with aquatic herbicide programs? What should they know about UPL?

30 | IRRIGATION LEADER | September 2021

Jeremy Slade: I think it has changed fairly significantly.

Over the last couple of years, there has been considerable consolidation. Manufacturers, distributors, and commercial application companies have made significant acquisitions and mergers. I believe customers are looking for stability within the industry. From that standpoint, it is becoming more apparent that we need to focus more on the customer, because at the end of the day, that’s who we’re working with. On top of that, there’s been a movement for pesticide safety. It’s now more important than ever for the industry to have a unified message. We have to have the tools to manage the issues we have in our waters. Having sciencebased information that we can provide to the end users and customers is vital for our ability to continue to have sustainable vegetation management and food development.

Irrigation Leader: What is your message to Congress and other policymakers about the safe use of aquatic herbicides?

Jeremy Slade: I think they need to listen to the users. At the end of the day, pesticides, specifically herbicides and algaecides, are tools that are needed in the field by the people who are providing our food and irrigation water. If we don’t understand what they need, we can’t provide viable options or solutions. To take that a step further, it would help to have the regulatory agencies get out in the field to see how these operations are run. A lot of times, their information comes from a piece of paper or what they are being told, so seeing it for themselves would be valuable, in my opinion. Discussing these things face to face with an applicator who has been applying a product for years would give some perspective on how it’s actually being used and the challenges users encounter. We also need to support the scientists who are doing research and developing these products. We’re getting into an age in which feelings and emotion are driving decisions, but those decisions need to be driven by science-based information.

Irrigation Leader: Can aquatic herbicides be used safely?

Jeremy Slade: Following the directions for use on a product label is the best way to ensure that you are using it safely and effectively. The label is the law. IL

Ecological Sustainability Should Be Our Goal

By Scott J. Cameron

PHOTO COURTESY OF SCOTT CAMERON.

A

s legislative and administrative solutions to climate change are being debated in Washington, DC, I encourage Congress and the Biden administration to step back and consider the larger challenge so that we accurately define the problem and can intelligently craft solutions to achieve our goals.

The big picture is our need for ecological sustainability, of which climate change is just one of four dimensions.

The three other key legs of the ecological sustainability stool in the United States include controlling invasive species; managing range and forest lands; and striking the right balance between extensive and intensive food production. Addressing global temperature alone is not enough to achieve ecological sustainability. Unless we take a comprehensive approach to all four of these challenges, we will lose the ecosystems that feed us, keep us healthy, and provide the natural resources we depend on for our physical and psychological well-being.

Invasive species are organisms that are nonnative to a particular ecosystem and whose introduction poses economic, environmental, or physical harm to human health.

They cost the U.S. economy in excess of $130 billion per year and are at least partially responsible for the status of more than 42 percent of the organisms on the country’s endangered species list. Some of the highest-profile invasive species are sea lamprey in the Great Lakes, kudzu in the Southeast, and Burmese pythons in Florida. The Biden administration should pursue a four-pronged defense-indepth strategy on invasive species: • Implement a more rigorous, but not draconian, regulatory and port-of-entry inspection system to keep invasive species out of the country.

• Create an effective monitoring network, coupled with a rapid response capability, to quickly detect and eliminate invasive species populations that leak through ports of entry before they can establish a firm foothold in the countryside.

• Target control efforts to deal with widespread invasive species so as to protect our most valuable ecological and economic resources.

• Conduct an aggressive applied-research program to create breakthrough solutions to more cost-effectively deal with invasive species that have already become widely established.

The most dramatic manifestation of our historically inadequate management of our range and forest lands is the ever-increasing threat to lives, air quality, property, and ecosystems from wildland fire. The summer fire season is irrigationleadermagazine.com

now a year-round fire threat. The intensity, size, duration, and frequency of wildland fires continue to worsen.

To save lives, property, and our range and forest ecosystems, the Biden administration should • aggressively reduce the buildup of fuels in our forests and rangelands that is the result of decades of misconception that all fire needs to be extinguished, even in ecosystems where, for millennia, small, infrequent fires have played a constructive ecological role; • achieve better coordination across all levels of government between the programs focused on invasive vegetation control and the programs focused on fuels reduction, since they often use the same practices in the same geographies; • increase investment in the post-fire rehabilitation of firedamaged areas to avoid recreating the situations that lead to catastrophic fire; and • incentivize state and local governments to make it harder for builders to irresponsibly site new houses in the middle of fire-prone forests.

Finally, we need to appreciate that the industrialization of agriculture has brought the expanded use of machines, technology, infrastructure, and chemicals that allow us to dramatically increase per-acre yields so that more food is produced in a smaller area using less water and more land is left in a natural condition. Aquaculture similarly holds out promise that wild fish stocks may not be as overfished in the future as in the past.

There are ecological tradeoffs between modern intensive agriculture and the growing interest in more-natural foods.

Less-intensive food production means more land cleared and waters fished and therefore less opportunity for fish and wildlife conservation. This reality needs to be thoughtfully considered if the country is to achieve the Biden administration’s goal of keeping 30 percent of our land area in a natural state.

Only a holistic approach that addresses climate change, invasive species, forest and rangeland management, and a thoughtful approach to agricultural production will allow us to achieve ecological sustainability for generations of Americans to come.

Worthington’s Offerings for New Zealand

In 2017, the catchment area above Lake Matahina experienced a flood of record. The TUFFBOOM barriers above Matahina Dam held back immense amounts of debris, preventing the spillgates and water intakes from being blocked.

I

n 2001, Worthington Products introduced its TUFFBOOM debris control booms to the world. Since then, Worthington has expanded into designing and fabricating fish guidance systems, public safety boat barriers, and public safety signs for use around dams. Worthington is active around the world, including in New Zealand and Australia. Many of its products are appropriate for irrigation and hydroelectric installations in New Zealand. In this interview, Worthington President and CEO Paul Meeks tells us about the products that will be of most interest to New Zealand water managers.

Irrigation Leader: Please tell us about your work in New Zealand.

32 | IRRIGATION LEADER | September 2021

Irrigation Leader: How many projects do you think you’ve done in New Zealand?

Paul Meeks: I used to know the numbers, but it’s quite a lot of installs.

Irrigation Leader: What is your message to potential clients in New Zealand?

Paul Meeks: New Zealand is a wonderful country with great water resources for irrigation, water supply, and irrigationleadermagazine.com

PHOTOS COURTESY OF WORTHINGTON PRODUCTS.

Paul Meeks: We have done quite a lot of debris control and public safety work in New Zealand. Our first international project was in Australia for the Snowy River hydroelectric scheme following devastating fires around 2002. Shortly thereafter, power companies in New Zealand got wind of our waterway barriers and requested that we provide debris control barriers and safety barriers at their dams. We have had a good relationship, and today, we have booms and buoys all over New Zealand.

In 2017, the catchment area above Lake Matahina experienced a near probable maximum flood event.

The result was a sudden, massive influx of debris. The TUFFBOOM barriers installed by Trustpower the previous year prevented the debris from reaching and

blocking the floodgates and water intakes. Althought it took 6 weeks to remove all the debris from the reservoir, the utility never lost a single minute of generation because the booms kept all the debris away from critical areas.

Trustpower estimates this saved it more than NZ$800,000 (US$564,920) in prevented generational losses alone. The client called us afterward to say that it could not have been more pleased with the performance. This was a flood of record, yet the booms prevented the dam from overtopping by keeping the debris away from the spillgates, allowing them to spill properly. The booms also kept all the debris away from the water intake. Not only was our client able to continue spilling water during a critical period, it was able to continue to generate power. It said that this was a huge payback that justified having booms around these dams and power plants.

This 720-foot-long Worthington fish guidance barrier, installed at Bonneville Dam on the Columbia River in Washington State, guides migrating salmon to the surface bypass for safe passage downstream.

hydroelectric power generation. With dam ownership, however, comes a responsibility to assure the safety of these dams—the structural safety, of course, but also the safe use of these water resources from a public safety perspective.

Much of the work on public safety around dams being done internationally relies on the dedicated work of dam engineers from New Zealand who serve on important committees with the International Commission on Large Dams. In addition to public safety, the safe operation of a dam includes preventing the blockage of water intakes and floodgates by debris or trash. As the folks at Matahina discovered, a sudden debris influx can have significant effects on the safety of the dam and on revenues. We encourage dam owners to consider how a debris control system can improve their operational reliability, reduce dam safety risks, and lower risks to the members of the public who recreate around these structures.

Irrigation Leader: Would you tell us about the work that you’ve done on fish barriers?

Paul Meeks: Our first fish barrier project was a massive system for the U.S. Army Corps of Engineers at the Bonneville Dam along the Columbia River in Washington State. Since that project, we’ve been highly successful in this realm. There are different types of fish barriers, including electronic barriers and physical barriers. We design physical fish guidance barriers. When I describe our work to a layperson, I tell them that we place a floating wall in a river or reservoir, usually 3 meters deep. The fish approach this wall and follow the current to a bypass or collection system.

We prevent them from turning into sushi! Of course, the irrigationleadermagazine.com

science behind these systems is quite complex and requires not just an understanding of barrier design but also a detailed understanding of fish and fish behavior. Placing a wall in the water sounds simple, but where we locate that barrier, what angle it is placed at, and how deep it is are all critical to whether it works or not. We have a fisheries biologist on staff who works closely with our engineers and clients to guide and inform us on the design as it relates to a particular species of fish. The success of fish guidance systems really comes down to locating and angling your boom to optimize the water’s surface velocity. The fish are going to follow the velocity. We see a lot of people go out and install fish guidance systems without spending the necessary time on velocities or positioning, and they end up getting an ineffective barrier that must be revisited and reconfigured multiple times to get it to function properly. We take time up front to understand the flows completely so that our clients’ guidance structures will achieve the ultimate level of success. In the United States, guidance systems are judged partially on how little water needs to be sent over the dam versus through irrigation channels or through turbines. If you’re passing water instead of putting it through a turbine or an irrigation canal, you’re basically throwing money away. We minimize the amount of water that has to be passed. IL

Agri-Inject: A Pioneer in the Chemigation Field

An Agri-Inject fertigation system hooked up to a center pivot.

S

ince the 1980s, Yuma, Colorado–based Agri-Inject has been advancing the use of mobile irrigation systems to apply fertilizer and chemicals in liquid form. This method of application, known as chemigation or fertigation, allows for the quick, low-volume, and continuous application of fertilizers and chemicals, thus spoon-feeding crops no more than they can absorb and preventing leaching and nitrate pollution. In this interview, Agri‑Inject CEO Erik Tribelhorn tells Irrigation Leader about the company’s role in developing chemigation from its beginnings and what the company is doing today.

Erik Tribelhorn: We manufacture chemigation and fertigation equipment that is designed to inject any liquid fertilizer, chemical, or water treatment product into irrigation pipelines.

Fertigation refers to the injection of fertilizers, and chemigation

Irrigation Leader: Please tell us about Agri-Inject.

refers to the injection of chemicals. That makes up 90 percent or more of our business. The systems we manufacture are available in a range of sizes and configurations that is unrivaled in the industry, featuring pump sizes from less than 1 to over 300 gallons per hour; tank sizes from 10 to 600 gallons; a wide range of voltage options, material compatibility options, and plumbing configuration options; and more. We want to make sure that any fluid injection application in the world can be successfully accommodated using our equipment and engineering expertise. In many industries, including agriculture, golf, and sports parks, our customers are using their irrigation systems to deliver fertilizers, chemicals, or pest-control products through their water in a way that is palatable to plants, sustainable for the environment, safe, and usually less costly than alternatives. We’ve been involved in those markets all around the United States and in a significant part of the developed irrigated world.

Irrigation Leader: How long have U.S. users been putting fertilizer through their pivots using your pumps?

Erik Tribelhorn: Our business was founded in 1983 and predominantly focused on the center-pivot irrigation ag market. Center pivots were developed back in the 1950s, and in the late 1970s and early 1980s, our founder began using fertigation on his own farm, then did it for the neighbors, and then began developing a business model.

Agri-Inject was involved in the formative years of liquid injection, when people were figuring out whether it worked, how effective it was, and what safety requirements needed to be in place on both the federal and state levels. If you look at the documentation that still exists on safety requirements in some states, you will see drawings that show our equipment, since we helped design safety protocols at that time. We certainly played a part in guiding the success of the chemigation industry in the United States.

Irrigation Leader: Why would a farmer opt to put fertilizer through their pivot?

Erik Tribelhorn: Farmers use fertigation for a variety of beneficial reasons. A primary purpose is that fertilizer that is delivered via irrigation water is delivered in a form that allows plants to readily uptake the nutrients. Plants are designed to take up liquids, not solids. Solid fertilizer needs to dissolve in water to be taken up by a plant’s roots. When you fertilize via irrigation, you are accomplishing that in one step.

Second, fertigation can be accomplished using equipment that the farmer already owns for a small capital investment.

In today’s market, quarter-mile center pivots are likely in the $70,000–$80,000 range. For a small percentage of that amount, you can equip your center pivot to fertilize for you.

The reliability and the features of our equipment make that process almost painless.

A third reason is that fertigation eliminates extra trips over the field. Using a sprayer or spreader, you are making trips through the field and around at the ends, compacting the soil where you’re driving, burning extra diesel, and risking drift and overlaps. Our technology runs in tracks that are already established. The fertilizer and chemicals go where the water goes.

The last point is that fertigation allows fertilizer application to be timed more closely in line with the usage of the plant. As a plant begins from a seedling and moves through its various growth stages, its usage curve of fertilizer is predictable. Since you’re watering in accordance with that growth cycle anyway, you can apply fertilizer at the appropriate times and at the rates the plant needs at that particular time. Plant-needs-based fertigation makes efficient use of nutrients and can have a similar effect on your cash flow. You can buy and use fertilizer when it’s needed. If you fertilize in two or three chunks and then get hailed out, much of the fertilizer that is stored in the ground is likely irrigationleadermagazine.com

to dissipate. If you spread your fertilizer application out according to the growth cycle of the plant, it is healthier for the plant and healthier for your risk management program.

Irrigation Leader: Does it also reduce the risk of the leaching of chemicals such as nitrates into the groundwater?

Erik Tribelhorn: When the amount of fertilizer applied matches the uptake rate of the crop, little fertilizer will escape through the root zone. If you’re methodical about that, there’s little chance of any event that would cause fertilizer to escape below the root zone and leach into the groundwater. The application timing enabled by fertigation is one of the best ways to prevent the nitrate leaching problem that is prevalent worldwide.

Irrigation Leader: A visit to your factory also demonstrates that your whole business focuses on efficiency. Everything is designed to be ergonomic, to reduce steps and movements, and to make things easy for your workers. There is a culture of attention to detail and efficiency. Please tell us about your philosophy and how it came to be.

Erik Tribelhorn: What you see when you take a tour of our facility is based on a culture we take a lot of pride in.

The complete factory facelift and reorganization had two rationales. First, we wanted to reduce or eliminate any limiting factors that might keep us from properly serving our customers. Second, we wanted create a factory that is unlike anything we had accomplished before, something our team could be proud of. In my first months on the job, it became obvious that the limiting factors were our ability to produce on time, our ability to manufacture our products with the required level of quality, and our ability to produce with the limited labor supply that we have in the area. Because our region is so ag oriented and because our community is small and hard working, the competition for good labor is pretty high. We needed to be efficient, to be a great place to work for existing and prospective employees, and always to be able to serve our customers. I had a vision for the plant, and the reality has far exceeded it because we never stop improving.

We want to make sure that we capitalize on what I consider to be one of our competitive advantages: quick delivery to the customer with a high degree of certainty that the product is going to be configured correctly so that the customer can put it to immediate use in the field.

Chemigation and fertigation products are usually not at the top of the list when a farmer thinks about what he’s going to buy for the next year. For us to be able to serve that last-minute mentality, we need to meet an immediate demand during the season. We must manage supplier lead times that are measured in weeks or months and still be able to satisfy our customer’s needs in days or even hours.

To execute at that level, we must make sure we are stocking the correct inventory at proper levels. Such inventory needs September 2021 | IRRIGATION LEADER

to be readily available in a usable form. To do that, work processes need to be well defined, production areas need to be well designated, and the tools for those work processes need to be immediately available and in good condition.

Only the tools needed for the task are at the work area, and those tools are either captured on tool balancers or designated with labels or shadow boards, so you can’t take them to a different project. All of that is intentional; it allows us to be responsive to our customer base.

Irrigation Leader: In your factory, all the tools are on retractable, spring-loaded tethers within hand’s reach of the worker. It keeps them in the same place and prevents them from cluttering the work area. Would you attribute that design to your farmer background?

Erik Tribelhorn: A little bit. The farmer never knows what he’s up against, while we do know what we’re up against. We can make over 1,000 different product combinations from the standard products in our database, but it all boils down to five product lines. The tools are fairly consistent within that product line. That’s different from what a farmer is up against, which is what I was used to dealing with.

Several factors led to the design of our factory. We started to study the factories of the companies we dealt with. We took tours of some of our center-pivot original equipment manufacturer partners, we visited the factories of many of our suppliers, and we took our entire production staff to the Schlage factory in Colorado Springs. We began to adapt some of the things that we saw—how product moved or was stored; how information was conveyed; how people moved, worked, and communicated; the tools that were used; how fixtures and jigs were used; and more. Ultimately, we became better at solving problems efficiently through the use of fixtures, specialized tooling, and even ergonomic conditions.

We trained ourselves to start to think that way. It’s a slow process, but it’s fun and rewarding. Now we know that regardless of the problem we are faced with, we can analyze it and devise a good solution. In earlier days, it was hand to mouth; now, it’s much more methodical and planned out.

It’s rewarding for both me and the rest of our team to arrive at solutions that way.

Irrigation Leader: You’ve certainly adopted the universal farming mentality of always doing more with less.

36 | IRRIGATION LEADER | September 2021

Irrigation Leader: What is your message to irrigating farmers who may have never thought about putting fertilizer through their pivots?

Erik Tribelhorn: I would encourage anybody with any type of irrigation in the ag market to give fertigation and chemigation some consideration. There are many benefits. The one thing that is still true is that using our products requires some work. Despite the fact that we have technology like ReflexConnect, which allows you to remotely control and monitor your system, it’s still a little more work than getting on the phone and calling somebody to apply fertilizer on your property or to get the aerial applicator out there. However, with our products, you’re in total control over your profit and loss statements, the efficacy of the process, and the timing of the application, and you can make sure you’re applying the right chemical in the right amount and that it’s getting on your crop and not your neighbor’s.

Fluid injection into irrigation provides benefits to yourself, your farm, and the environment. It’s one of the cleanest and safest application methods in the industry.

Once the injected liquid is encapsulated in that water and applied through virtually any irrigation method—center pivot, solid set, golf/turf type underground, drip—there’s little chance of drift or off-target application. I would encourage all growers to look at fertigation and chemigation as options for applying these products to your crop. It’s a process that has always been safe, reliable, and precise.

Our application equipment was some of the first precision ag equipment, and it continues to be. Chemigation and fertigation reduce cost and risk; have a return on investment measured in days, not years; and when it comes to efficacy, the growth of your crop, and the environment, are the smarter choice in the long term. As the global population grows and environmental considerations grow more important, this should be the future of fertilizer and chemical application. IL

Erik Tribelhorn: That’s true. We have the same problems as manufacturing companies that are 10 times our size, but instead of having 200 people to deal with them, we have just 21. Bigger manufacturers can devote teams of people to a single area within the business, while we might have one person for whom that area is only 10 percent of their job, and the rest of us have to come in to support. Knowing how to do more with less is what we’re all about, because there’s no other way. We all have

regular jobs within the business, we all have different priorities, and we have to team up to solve those problems as they arrive and do so with the resources that we have.

That makes it even better, honestly. It’s challenging and stressful, but when you get it all done and step back, it is very fulfilling.

Chris Gargan and Joel Irving: Providing Global Screening Solutions at International Water Screens

filter out debris while preserving fish, and are designed to last.

In this interview, IWS Vice President Chris Gargan and Sales Representative Joel Irving tell Irrigation Leader about IWS’s product line and how it is expanding globally to meet water challenges on nearly every continent.

Irrigation Leader: Please tell us about your backgrounds and how you came to be in your current positions.

Chris Gargan: I’m the son of the owner and am now the vice president of sales. I began about 15–16 years ago and have been enjoying it ever since. I work for my dad, Rich Gargan, who worked for his dad for 18 years before starting IWS. I appreciate the opportunity to get to travel to a lot of places I might not otherwise be able to. I absolutely love working for my dad and with my brother-in-law. We’ve been fairly successful at keeping roofs over all our heads and food in our mouths.

Joel Irving: I grew up on a cattle and grain farm in Saskatchewan, Canada, and chased the professional hockey dream for about 15 years. I ended up in Bakersfield, California, where I met my wife, Monica, who is Chris’s sister and Rich Gargan’s daughter. Once the hockey career was over, I needed to transition over into another passion.

Rich gave me the opportunity to learn about his company and where he wanted to go with it, which involved being more aggressive in Canada and the northern United States. I took on the challenge and worked out in the shop for about 6–8 months. Then he said, “Go,” and I said, “Where?” He basically told me to go somewhere and sell screens. I go into engineering firms and do presentations at trade shows. Like Chris says, it’s been a good transition for me because I still get to travel. That feels like what I used to do all the time.

That’s exciting for me, and it’s been a great opportunity.

Irrigation Leader: Were the skills that you learned growing up on a farm conducive to working in the shop at IWS? Joel Irving: Absolutely. I don’t think I had ever experienced heat like the heat of the shop here in Bakersfield, but I got through it. If you want to learn about your product and be able to sell it properly, you need to dig into the nuts and bolts and find out how it operates. That’s what I had to do, and I learned from the best—our service guys.

Chris Gargan: We’ve been in business since 2003 with the objective of protecting pumps, irrigation pipelines, and irrigation systems by screening out debris. We manufacture what’s called a traveling water screen as well as troughs, conveyors, elevators, and many other bells and whistles. In the beginning, irrigation was our main focus, but we’ve branched out to many other industries, including wastewater treatment; irrigationleadermagazine.com

ne challenge that is common to irrigation districts and water users worldwide is the need to remove debris and other substances from water while also protecting fish and other wildlife. Screens that can filter out debris without harming fish are important tools for doing just that. International Water Screens (IWS) is a global leader in the design of fixed and moving screens. Its screens are custom built to customers’ needs, feature state-of-the-art features to

fish facilities; hydropower; other types of power plants, including geothermal and coal; and cooling tower applications.

Joel Irving: If you have debris in your water now, you Google it, come up with IWS, and contact us and explain the issue.

Alternately, you meet Chris and me at a presentation or trade show and shake our hand. We start from there.

Irrigation Leader: What is the size range of your screens?

Chris Gargan: The smallest screen that we have built was 18 inches by 7 feet. The largest was over 13 feet by 80 feet.

We have also built just about every size in between. We have also built screens for vertical installation, horizontal installation, and every angle in between.

Irrigation Leader: Please tell us about your fish screens.

Chris Gargan: They are used at fish hatcheries, dams, runof-the-river pump stations, recreational lakes, and the inlets to power plants and chemical plants. The openings in fish screens range from 1 millimeter to 2 inches, depending on the type of fish or wildlife the customer is trying to protect or exclude from their system.

Irrigation Leader: Are your fish screens typically traveling or stationary? irrigationleadermagazine.com

Chris Gargan: Our main focus is on traveling screens, but we also do stationary screens, trash racks, or stationary Grizzly screens. Typically, if you’re going to put up some type of screen, it makes most sense to choose an automated one so that you can reduce labor, risk of injury, and lost time, increasing the efficiency of your pumps and irrigation systems.

A lot of customers see real cost benefits because of that.

Irrigation Leader: Does the traveling aspect of the screen increase the fish survival rate?

Chris Gargan: It does. It consistently reveals the clean screen surface as it travels, whereas the stationary screen will continue to get plugged until it’s manually cleaned. That’s one reason that a traveling screen increases efficiency: it prevents you from losing the flow of water into your system.

Joel Irving: Every location has different criteria for approach velocities. In some locations, you need to remove tons of debris, so an automated screen is best. Meanwhile, it also prevents fish from becoming impinged.

Irrigation Leader: Where around the world have you installed your traveling fish screens?

Chris Gargan: Algeria, Canada, the Dominican Republic, Indonesia, Puerto Rico, and locations in South America.

The international projects are mostly larger projects. All of them have multiple screens—between two and five. I’d say the smallest we have shipped out were probably two or three screens that ranged from 6 by 20 feet up to just under 10 by 35 feet. The screens we shipped to Indonesia were 10 by 40 feet. We shipped them in sections to be assembled during installation. We can also ship complete units. For a project in Peru, we just shipped material down and sent our service man and some tools, and he actually fabricated the screens in Peru. There are lots of options for getting equipment to a location.

Joel Irving: Our international projects also vary in terms of their purpose, from turnouts to power plants to firewall protection plants. In Canada, we have screens from Halifax, Nova Scotia, on the East Coast all the way across to Vancouver on the West Coast. The projects are all different sizes.

Irrigation Leader: Do you have an office in Canada?

Joel Irving: We do, and it’s still growing. We foresee some big projects in Alberta and Saskatchewan this year, so we are preparing for that.

Irrigation Leader: What materials do you use in your screens, and how long do they last?

Chris Gargan: We fabricate using all types of material, including mild steel, stainless steel, and duplex materials.

We have stainless steel in grades including 304, 316, and 317. A lot of saltwater applications require 316 stainless steel. As with a vehicle or any operating piece of machinery, with minimal maintenance, they can last just about as long as you want them to. Every 7 years or so, they should also have somewhat more extensive maintenance, such as the replacement of stretched or worn chains, bearings, strips, and weathered surfaces. Generally speaking, they’re built to last. The first screens Rich sold are still in operation.

Irrigation Leader: What is the average time frame from the beginning of a design until installation?

40 | IRRIGATION LEADER | September 2021

Irrigation Leader: What differences do you notice when working with different industries, countries, and projects?

Chris Gargan: Nothing is cookie cutter. Everything is unique.

The larger international projects are less often at simple irrigation projects and more often at power plants, chemical plants, refineries, and mines. We go through a more extensive submittal and approval process with them. A lot of our overseas projects are with large international corporations.

They’re well-known names in the power and fuel industries.

They’re sticklers for their submittal and approval processes.

We have no issue with that. We want to make sure that we are doing everything that is necessary for every company.

Irrigation Leader: What should readers know about IWS’s warranties?

Joel Irving: Our service is second to none in this business.

That doesn’t mean that we just give service to the guy down the road from our manufacturing shop; we give service to every single customer, whether they have a massive project or just a simple ag screen. If they call us and are having issues, we’re going to handle them. If somebody calls in Canada and says they have issues with their screen and they need us to come up, we’re on a plane that day or the next.

Chris Gargan: We definitely pride ourselves on our service.

Our philosophy is to offer a good product at a good price with great service and thereby earn customers for life. That’s what we strive to do every day.

Joel Irving: We want to sell multiple screens to our customers and have a goal of generating friendships with them. They’re not just customers to us, they’re friends. We consider every project to be one of our babies, and we want to make sure that they’re running for as long as possible.

Chris Gargan: Our typical lead time from notice to proceed to shipping is 6–10 weeks, depending on the time of the year. Sometimes, 2 years might pass from the time we meet a customer at a trade show, give them a presentation, or establish contact through an internet inquiry and the time we finally deliver a screen. We can turn around a conceptual design and a budget quote within a week. Often, the customer will then consider it and do their due diligence to decide whether it works for them. While doing so, they will be paying close attention to their turnout, inlet, or system and may start to notice more issues. They start to realize that the value will be there, and of course they have to budget for it. Often, they follow up the following year.

Joel Irving: We make contact with these customers early on. It could be 5–7 years by the time they understand their situation and how our screens can benefit their company and get the money in place.
