Movable dam conquers Nakdong River
The South Korean city of Busan is threatened by flooding from the Nakdong River during the rainy season. Due to climate change and the silting up of channels, the current barrier no longer provides satisfactory protection. On behalf of the South Korean government, DHV has designed a new barrier with moveable sluice gates. Drawing comparisons with the Haringvliet Barrier in the Netherlands, the dam will double the river’s drainage capacity whilst protecting the city, agricultural land, and green areas. Over 20 years ago DHV was also involved in the construction of the present barrier, which consists of a fixed dam in one branch of the river and a movable dam in the other. The new dam will replace the current fixed barrier and will be approx. 300 meters in length. The dam has five vertical sluice gates, of which the central one is 100 metres wide. A bridge will be built over the dam. Construction will begin this year and is scheduled for completion in 2012. DHV is working closely with Samsung Engineering & Construction and Yooshin Engineering Corporation on the project.

We regularly hear reports of serious flooding, yet we are also told that there is a worsening shortage of clean water. This seemingly paradoxical situation is by no means uncommon. In the rapidly growing major cities of Asia, for example, the demand for drinking water competes with the interests of nature conservation and flood protection. How can we ensure that a city has an adequate supply of drinking water, that waste water is recycled and reused to the greatest extent possible, and that the city remains protected against flooding? Cities which provide answers to these questions are now being built in China. They are known as ‘Eco Cities’. DHV is closely involved in their development, as you can read in this edition. The theme of ‘drought and flood’ is one which demands urgent attention in various regions of the world. In Indonesia, a country rich in water, there is a shortage of fresh water. In fact, the same can be said of some parts of the Netherlands. This raises a number of questions: how much water do we actually use, in other words what is our ‘water footprint’? How can we reduce that footprint to the greatest extent possible? It is crucial to create greater awareness of our water footprint and to find ways of managing our planet’s water resources in a more effective way. International cooperation will enable us to make significant progress in doing so. The DHV Group is actively involved in various water projects, all of which will help to create a more sustainable society. For example, we conduct Water Footprint assessments (see page 20) and we advise governments about how climate change will affect their countries (see page 20). An increasing number of public and private sector organizations, as well as private individuals, are starting to realize how important it is to use our natural resources responsibly. DHV can help them to do so, and we can provide a good example. After all, that is in the interests of everyone in the world today and the generations yet to come.

Chinese cities break with planning traditions three eco cities in china
The Chinese economy is booming. Ever-expanding employment opportunities along the eastern seaboard are acting as a magnet to workers from the vast interior of the country. In order to provide housing for all these migrants, the Chinese government is expanding existing cities on a massive scale, or even building entirely new ones from the ground up. Amidst this flurry of construction activity, the ‘Eco City’ concept is gaining ground. The Chinese government is making extensive use of DHV’s expertise in order to break with the space consuming planning methods of the past. The aim of the new concept is to realize a healthy urban environment, in balance with existing water and energy supplies and natural resources. The provinces of Hebei and Tianjin on the shores of the Bohai Sea in northeastern China are setting the eco trend by expanding the cities of Cangzhou, Caofeidian and Tianjin. Massive mudflats lie off the coast at Caofeidian, a modest sized city on the shores of the Bohai Sea. It is hard to imagine that in just a few years’ time, one million Chinese will be
living here. With several industrial parks and a massive port complex, the expanded city will serve as a new economic powerhouse for northern China. But this powerhouse will belong to a new generation: compact, adapted to existing environmental conditions, low on energy consumption and CO2 emissions, and with extensive facilities for collecting and reusing fresh water. “By Chinese standards, this is a revolutionary approach”, says project leader Dick Kevelam.
DHV is closely involved in expansion programs for three Chinese cities: Cangzhou, Caofeidian and Tianjin. In all cases, the key question is how to reconcile the expansion with a shortage of fresh water, the risk of flooding and the aims of nature conservation. In its various projects, DHV works alongside renowned partners such as the Chinese planning institute Qinghua, the British consultancy Arup, the Dutch knowledge institute Alterra and the architects of Architecten Cie, another Dutch company.
Together with business developer Tiffany Tsui, he is helping to plan the massive project. “Existing Chinese cities were all developed according to the American model: on a large scale and with long, wide thoroughfares. Residents can’t get anywhere without a car. The result is high energy consumption and a great deal of pollution. The Caofeidian of the future will be much more compact, with metro and light rail lines and particular attention devoted to wind and solar energy.”
necessity is the mother of invention
“It’s largely out of necessity that the Chinese government has chosen to develop Caofeidian using sustainable methods”, says Kevelam. “There’s simply little room for urban development in this densely populated part of China. All the existing agricultural land is needed >>

Land reclamation from the Bohai Sea is an attractive option.
Necessity is not the only factor driving the push for sustainable urban development. Environmental awareness is very much on the rise, says David Ji, Director of DHV China. “Sustainable development is high on the national policy agenda, and a great deal of attention is devoted to new spatial planning methods. We really have no choice, given the current growth of the Chinese economy and population. In
this country, the Eco City concept is the only solution for accommodating such massive growth.”
nature driven design
In addition to Caofeidian, DHV is designing similar development projects in Cangzhou and Tianjin. Here, too, the main focus is on urban planning combined with maintaining the ecological balance and devising systems for rainwater collection. All three projects are based on the concept of ‘Nature Driven Design’, DHV’s vision for using natural processes to create sustainable water solutions. “Our plans are based on the existing natural environment, such as old river beds and laguna islands”, Kevelam explains. “Why build something new if you can make use of what nature provides? This approach saves a great deal of time, money and effort, and helps enhance the ecological value of the area being developed. For instance, old and disused river beds are very suitable for water storage, and raised islands off the coast can be developed without destroying the laguna structure. It’s not very difficult to devise such plans, but you must have an eye for the possibilities offered by nature.” “Our great strength is that we can call on multidisciplinary expertise to suggest solutions

to feed a large population. This makes land reclamation from the Bohai Sea an attractive option. Fresh water shortages are also driving a more sustainable approach. In fact, an adequate supply of fresh water is essential for these urban development projects.” DHV’s plans are mainly concerned with collecting and retaining fresh rainwater. “In this part of China, most of the annual rainfall is concentrated in a period of just two months”, says Kevelam. “In the past the excess water was discharged to sea as quickly as possible, which resulted in the land drying out and drinking water shortages during the remainder of the year. We proposed storing the water in the soil to be pumped up later, instead of letting it drain away. Wastewater must also be reused, so that all the existing water resources are utilized as efficiently as possible.”
that individual specialists could never develop on their own”, Tiffany Tsui adds. “These qualities are very much appreciated by our Chinese clients.” Tiffany does put the Eco City concept into perspective, however. “It’s not a cure-all solution for the problems posed by growth. People shouldn’t expect miracles, as there is no single, easy solution for dealing with the issues of rapid urbanization. Every situation is different and poses different challenges. We tackle these in a practical, level headed manner. But we never lose sight of the underlying principle: finding a balance between ecological, economic, agricultural and urban interests. This is an approach which can be applied anywhere in the world.”

Mozambique’s capital Maputo is located downstream of the Incomati and Maputo rivers.
New ring road Eindhoven
Water knows no borders
The new ring road serving the southern Dutch city of Eindhoven is finally complete. In early June transport minister Eurlings officially opened the widened motorway, which is expected to put an end to the daily traffic jams around the city. DHV’s traffic management experts were involved in the project from start to finish, providing advice to the Department of Public Works and Water Management, the Eindhoven City Region Authority, neighboring local authorities, and electronics giant Philips (which has established its High Tech Campus on the outskirts of Eindhoven). During the preparation stage, DHV was commissioned by the City of Eindhoven to calculate the expected traffic flows and to advise on the design of the ring road and its connections to the city’s road network. As part of a regional-based collaboration project aimed at optimizing accessibility, traffic circulation was improved through a range of measures including synchronized ‘green wave’ traffic lights and multi-lane roundabouts (‘turbo’ roundabouts), allowing the roads in question to serve as alternative traffic routes whilst the construction work was carried out. DHV also advised Philips High Tech Campus to ensure that traffic to and from the campus is able to reach the ring road via a dedicated feeder road. We also supported the regional traffic control center while the work was carried out, with the aim of enabling motorists to continue using the motorway whilst it was being widened. Finally, DHV served as project leader for a special website that allows road users to find out exactly where and when road works are being carried out in the region.
Cross border rivers are often difficult to manage due to the conflicting interests of the countries through which they flow. This is why South Africa, Mozambique and Swaziland signed the Interim Incomati Maputo Agreement (IIMA) in 2002, with the aim of sustainably managing the cross border basins of the Incomati and Maputo rivers. A Tripartite Permanent Technical Committee (TPTC) is coordinating preparations for the signing of the final treaty, which is expected to take place next year. DHV, SSI and SEED are supporting the Committee by coordinating ten international water projects, with financial support from the Dutch government.

The consortium of DHV, SSI and SEED is advising the three countries on the development of a joint vision for sustainable management of the two river basins. It is also in charge of preparing and implementing ten water projects in the lead up to the signing of the definitive treaty in 2011. The projects cover such topics as information exchange, prevention of floods and drought, integrated water management, and water quality management. One key project concerns a study into the water requirements of Mozambique’s capital Maputo, which is located downstream of the two rivers. The study will determine how much water is required to meet the city’s needs, and how much can be used for agricultural and other purposes. Another project covers river basin disaster management and is aimed at jointly preventing and responding to disasters such as floods and severe pollution of river waters.

Dutch heritage in Nanjing
The highest section of a replica of a Dutch windmill was completed recently in the Friendship Park in the Chinese city of Nanjing. The windmill is a gift from the Dutch municipality of Eindhoven, in honor of the 20-year anniversary of the friendship between the two cities. In addition to the windmill, replicas are also being constructed of a water mill, farm and chapel, the originals of which are in the Province of Noord Brabant. DHV was commissioned by the Municipality of Eindhoven to create the designs for the four structures and to take care of the project management. All construction work is scheduled to be completed by September of this year.

Rehabilitation for coast of Zuid Holland province Lenie Dwarshuis - Van de Beek.
The Holland Water Week will take place in Shanghai in June. At the expo, Dutch water experts will showcase their extensive knowledge in water management, water treatment and drinking water technology. The Dutch province of Zuid Holland is taking the lead in the event. Member of the Provincial Executive Lenie Dwarshuis – Van de Beek is the enthusiastic ambassador representing the Dutch water sector in China. The province of Zuid Holland is about to experience a world first in the field of hydraulic engineering. At the end of this year, construction will begin on the so called ‘Sand Motor’ project in the North Sea, near the coastal village of Ter Heijde. This is the first time that the force of the sea will be utilized to strengthen the coast (see inset). Member of the Provincial Executive Dwarshuis is very proud of the project. “It represents a completely new and innovative approach to tackling coastal reinforcement combined with coastal expansion. It has taken five years of talks, but I am glad that we have the vision and confidence to undertake such a venture in the Netherlands once again. If the Sand Motor does what it is designed to do, it will prove to be a hugely attractive export product.” Water management and exporting this unique Dutch knowledge to other countries are two subjects that Dwarshuis takes a very close interest in. She has been actively promoting the Dutch province and the companies and knowledge institutes associated with it for years throughout the Chinese provinces of Hebei and Shanghai. “In 2003 we decided to strengthen our existing affiliation with Hebei Province, with a particular focus on water, environmental issues, and har-
bor development. This turned out to be very much in line with the requirements of the Chinese. They are looking for solutions to specific problems such as wet winters and extremely dry summers, and also require designs and plans for large new ports. Of course, the Port of Rotterdam is an excellent example of our skills in this field.”
coastal program
Zuid Holland also faces specific water problems which are being exacerbated by climate change. Due to the fact that most of the province lies below sea level, extensive coastal protection is of vital importance to its inhabitants. This is why the province is utilizing a coastal program to work towards a coast that is both safe and attractive. “Until now we have neglected the coast and, in many places, built to the very edge of the dunes”, says Dwarshuis. “Because of this, you could say that local residents have lost contact with the dunes and beaches to some extent. We know that the sea is there, but we cannot really see it. As such, the area is no longer very attractive in terms of natural beauty and recreational opportunities. The coast must become our front garden once again, so to speak.” Zuid Holland also faces a growing shortage of
nature driven design
The Sand Motor is a prime example of ‘Nature Driven Design’, DHV’s vision for using natural processes to create sustainable water solutions. The Sand Motor project involves depositing a large quantity of sand in the sea along the coast. Wind, waves and tides will then spread the sand along the coast. This will result in long term safety and more room for flora, fauna and recreation. The Sand Motor is an initiative of the Province of Zuid Holland in collaboration with DHV and the Dutch Ministry of Transport, Public Works and Water Management.
freshwater for agriculture and industry. These sectors require huge supplies of water, but large volumes of river water – which act as a natural buffer against sea water seeping in – are being lost. “With regard to the short term, we want to keep freshwater levels as they are. In the long term, I don’t know if we will still be able to achieve this. Therefore we have to consider other methods of preventing seawater from intruding in these areas whilst maintaining sufficient levels of freshwater. With our technical expertise and skills, I am certain we will be able to find an effective solution to the problem.”

Sanitation top priority for Indonesia
Just one percent of Indonesia’s 230 million inhabitants live in a home that is connected to the sewer system, and twenty percent have no access to a toilet. The Indonesian government wants to remedy this situation in 330 cities across the archipelago in five years’ time, thus taking a major step towards achieving the UN Millennium Development Goals. The improvement plans are based on a project method developed by DHV and its Indonesian partner PT MLD which has already been successfully implemented in twelve cities on a pilot basis. The method empowers local authorities to devise and implement their own program of improvements. Where necessary, a team of consultants provides advice to both local administrators and the national government on devising and executing the plans. “Until recently, sanitation wasn’t a top priority for Indonesia”, says project leader Jan Oomen. “In the local culture it was considered inappropriate to discuss the, shall we say, ‘fecal aspects’ of the issue. But that has all changed. Now politicians can actually win votes by supporting the introduction of proper sanitation. And that’s an excellent development.”

DHV is designing a major barrier in the Yongam River, South Korea. The winning design is a movable barrier 330 meters long that forms an extension of the existing dam. When high river discharges occur the structure will make it possible for the water to flow into the sea. The structure also provides protection against high water coming from the sea. The existing dam cannot let water run off into the sea, resulting in frequent flooding in the lower courses of the river. The Yongam project is linked to the 4 Major Rivers program of the South Korean government. This program will revitalize the four principal rivers of the country and retain fresh water. The client is the Korean Rural Community Corporation. DHV is cooperating with Korean company Hanyang and the Dutch firms KDb architects from Doetinchem and Bosch Rexroth from Boxtel. Construction is due to start this year.

DHV has entered into a contract with the Veluwe Water Management Authority which covers the replacement of the existing wastewater treatment plant in Epe with one which relies on Nereda® technology. Veluwe therefore becomes the first water authority to apply this innovative and sustainable technology at full scale. The new plant in Epe is expected to become operational in mid-2011. Nereda® technology has seen rapid development and refinement in recent years, with pilot plants and demonstration projects in South Africa, Portugal. The technology offers an exceptionally sustainable solution. The strength of the Nereda® system is that the organisms which purify the water are in the form of compact, concentrated pellets rather than the floccules found in conventional installations. This greatly reduces the space requirement and the consumption of both energy and chemicals.

fiftieth scan for business premises The report of DHV’s fiftieth quality scan for business premises was recently presented to Loek Hermans, president of MKB Nederland, the organization which represents small and medium-sized enterprises in the Netherlands. “Scans like this help us to halt the degeneration of existing commercial and industrial sites,” commented Hermans. “They are a very effective way of ascertaining the precise condition of a site.” Mr. Hermans went on to state that the revitalization of existing business premises is just as important
to the small business sector as the creation of new facilities, or perhaps even more so. The Quality Scan for Business Premises is based on an assessment of the site’s facilities and potential. The system is comparable to that used to rate hotels, whereby a site can be awarded up to five stars. The rating is a good indication of the quality and potential of the location and what businesses can and should expect. Over the past three years, DHV has rated many business locations in this way, most in the provinces of Overijssel, NoordBrabant and Limburg.

Giant bathtub

The Volkerak and Zoommeer lakes are located in the Rhine Meuse Scheldt delta in the south west of the Netherlands. In effect, they act as a giant bathtub, collecting any excess river water that fails to drain into the North Sea due to heavy storms. This type of situation is occurring more and more frequently as a result of climate change. DHV has calculated whether the various dikes, dams and barriers will be able to contain such massive volumes of water, and what the effects are on the environment. Furthermore, all necessary dike improvements have been inventoried. The ‘Room for the River’ project agency has now asked DHV to design the proposed upgrades, conduct an environmental impact assessment, apply for the necessary permits, and draw up a so called National Integration Plan. The Volkerak and Zoommeer lakes must be able to withstand even the severest storms by 2015.

The NPC is a new institution established to develop a national vision and long term strategic plan for the country’s development. It will also produce evidence-based inputs into the policy process on broad cross-cutting issues that have long term implications for our development. Its first output will be Vision 2025 and a long term strategic plan. The Vision 2025 will be an articulation of the type of society all South Africans would want to see in about 15 years time. It will set out the high level aspirations for the nation in terms of social, economic and political development. The long term strategic plan will be the plan to achieve that vision. It will attempt to define the path to achieve the particular objectives set out in the vision, defining the is-
The Commission has only just been established and no specific tasks have yet been assigned to Commissioners. However, we are part-timers and our main role will be advisory. Key issues that have already been identified include food security, water security, energy choices, economic development, poverty and inequality, structure of the economy, human resource development, social cohesion, health, defence capabilities and scientific progress. There is also provision for Commissioners to lead investigations into critical long term trends, with technical support from a Secretariat and in partnership with relevant other parties.
What are the main water challenges South Africa is facing in the 21st century?
South Africa is moving to a situation in which the majority of its water resources are fully used and those that are not are economically difficult to exploit. So the challenge is >>

to live within our means even as the economy of the country grows and peoples’ quality of life improves.
What should be done to solve South Africa's main water problems?
The general recommendation in situations such as South Africa’s is to intensify water resource management. That is not just a technical matter. It must be done in a way that ensures that all those concerned, from householders and farmers to mining companies and municipal managers as well as politicians, understand the limits that water availability places on the society. Allied with that, it is important to protect the quality of the limited water that is available. We cannot afford to pollute a resource that can’t be replaced and that others depend on. For these reasons, it is encouraging that water security has been identified as a key focus area for the NPC.
Can South Africa solve the water problems by itself?
As a matter of practical necessity, South Africa has historically been an international leader in water resource management and has established institutions such as the Water Research Commission to maintain this. The fact that supplies are reasonably assured and that investments have generally been made at the right time to avert shortages is testimony to that. However, it will be challenging to meet the new demands that are being placed on the resource although in many cases the challenges are more of operational management than of new knowledge.
What can other countries do in facing the future?
In today’s world, knowledge and expertise flow from one country to another and both sides usually benefit. South
NPC
The National Planning Commission of South Africa is a government agency responsible for strategic planning for the country. The NPC is tasked with producing reports on issues such as climate change, water security, food security, energy security, infrastructure planning, human resource development, defence and security matters, the structure of the economy, spatial planning and demographic trends. The members of the commission represent different areas of expertise and reflected a diversity of experiences and perspectives,
Africa benefited greatly from international experience when we were developing our water policies. Subsequently, many countries have drawn inspiration from the products, notably South Africa’s approach to addressing basic human needs and environmental protection. There is also recognition of significant operational achievements such as our major inter-basin transfers and pioneering work on land management to control the impact of afforestation and alien vegetation on water availability. I am sure that these exchanges will continue.

DHV has won the ‘Vernufteling’ award for 2010 with its idea to filter phosphate and ammonia from wastewater and to generate green energy. The Vernufteling is awarded to the most innovative and appealing project in the field of engineering in the Netherlands. The concept fits in seamlessly with existing wastewater treatment processes and can therefore be implemented on a large scale. In addition to providing cleaner water, the new idea saves energy, prevents CO2 emissions and recovers phosphate from the waste stream. Furthermore, this new process is considerably more cost-effective than the method of nitrogen removal currently employed in wastewater

creates pure MgHP04 crystals. These crystals are separated into phosphate and ammonia in a decomposition reactor. The phosphate can then be reused in the phosphate processing industry, either as an environmentally friendly alternative to mined phosphate ore or as a fertilizer. The ammonia is highly pure and extremely suitable for generating green electricity by means of a fuel cell. The purified wastewater flows back into the wastewater treatment facility. info Peter Luimes telephone +31 33 468 22 87 e-mail peter.luimes@dhv.com

news in brief
Will the area be able to withstand prolonged periods of drought?
The production of cotton requires many liters of water.
Policy makers use climate scans
Water footprint measured
‘Foresight is the essence of government’ is a well known Dutch expression. Climate change has made this long standing adage more relevant than ever. After all, is it even sensible to invest in a new residential district or nature reserve when we don’t know if the area will be able to withstand prolonged periods of drought? What about the danger of flooding due to heavy rainfall? And what measures should we take now in order to protect existing residential areas in the future?
It may not be something you think about every day, but did you know that it takes 15,500 liters of water to produce a kilo of beef? It takes 70 liters of water to grow just one apple, and 40 liters to produce a single slice of white bread. The production of a cotton shirt requires 2,700 liters of water.
To help Dutch policymakers take the right decisions in these matters, DHV has introduced the ‘climate scan’ tool, which is based on detailed climate scenarios incorporating the most likely long term changes in weather patterns. The tool was developed in collaboration with Dutch research institute Alterra and the Royal Netherlands Meteorological Institute. All Dutch provinces are now using climate scans to substantiate key spatial planning decisions. The results of all these climate scans have been compiled and made available in the form of an interactive website known as the ‘Climate Impact Atlas’. The website contains spatial information about the effects of climate change and is continually updated with the latest information, making it the leading source of practical, scientific background information in the field. The Atlas can be found at http://klimaateffectatlas.wur.nl (Dutch only).

The quantities of water that we all use – our so called ‘water footprints’ – are huge, while water itself is becoming ever scarcer. What impact does production have on the environment and on society? Furthermore, how can we ensure that food, clothing and other essentials are produced in a more efficient and sustainable manner? DHV is conducting Water Footprint Assessments in order to find answers to these questions. The assessments show how many liters of water are used in the production process, as well as the long term impact of these activities on the environment. They also indicate what can be done to make a positive contribution to the environment and the production process. An international producer of foodstuffs recently commissioned DHV to analyze the water footprint of two of its products. Among other purposes, the results will be used to further develop an international standard for assessing water footprints.

Managing Tagus river basin Manuel Lacerda.
The Tagus River (Portuguese: Tejo) is the longest river on the Iberian Peninsula. In Portugal, it is a river basin which encompasses almost one third of the population, major agricultural areas, and several industries. Dozens of hydroelectric dams can also be found in the Tagus river basin. Manuel Lacerda, chairman of ARH do Tejo (Tagus River Basin District Administration), tells DHV Times about the river and the measures that need to be taken in order to protect the river from pollution and flooding. As a public institute, ARH is responsible for protecting and managing the water resources in the Tagus area since October 2008. Mr. Lacerda is the first chairman of ARH: “We have a team of over a hundred people managing the river. Additionally, external parties such as DHV SA are contracted for specific tasks, including preparation of river basin management plans and the development of plans for the estuary and the coastal areas. We have also established partnerships with various municipalities and other public and private organisations as a means of increasing the efficiency of water resources management. As the river is shared with Spain, both countries are working closely together in order to protect this water resource and all its ecosystems.” The Tagus River is 1,038 kilometres long, a body of water blessed with ecological diversity and which traces its route through some truly remarkable landscapes. It is a habitat for many species, as well as being a sanctuary for migratory birds. There are two large natural reserves in the Tagus river basin: the Natural Reserve of Tagus Estuary and the Natural Park of Interna-
tional Tagus. The Tagus’s estuary is one of the Europe’s biggest and it is an important port area. As such, the estuary represents a major hub for the transportation of goods and people. Lacerda: “Our biggest concerns are pollution, siltation of major sections of the river, the restoration of extensive sections of dikes, and flood control. To tackle these problems, we have to fully implement the water resources policies, such as reviewing the current discharge permits for waste water. Dredging may also prove necessary to control the problem of silting and to promote the development of several navigation-related activities.” A major instrument for protecting and managing the Tagus River system is the river basin management plan. It highlights the main issues regarding the Tagus River ecosystem and the measures to be implemented in order to protect and valorise it. The plans are drawn up under the European Union Water Framework Directive. DHV SA has been assigned to develop the plan for the Tagus River Basin. “New river basin management plans will set
water framework directive
Protecting the quality of Europe’s water resources is a high priority for the EU. The Water Framework Directive establishes a legal framework to protect and restore clean water across Europe and ensure its long-term and sustainable use. The directive establishes an innovative approach to water management based on river basins, and sets specific deadlines for Member States to achieve ambitious environmental objectives for aquatic ecosystems. In order to comply with the EU directive, the Tagus River Basin District Administration commissioned DHV SA to carry out extensive river basin management studies on the Tagus River. DHV SA is also responsible for a basin study on the other major Portuguese river, the Douro.
the objectives to be achieved in each water body, including environmental quality standards and criteria for allocating water resources among various users. Such plans also define the measures necessary for achieving these objectives. Our approach will comprise the development of tools to support management and decision-making, which will be tested in a number of selected sub-basins”, says Mr Lacerda.

Dutch water management in danger curriculum vitae ‘Thinking of Holland / I see wide flowing rivers / slowly traversing / infinite plains’. What citizen of the Netherlands isn’t familiar with this, the first stanza of Hendrik Marsman’s famous poem Memory of Holland? After all, it was only a decade ago that Memory of Holland was selected as ‘Dutch Poem of the Century’. But Marsman’s Holland seems to be adrift on the seas of political change. With the nation’s financial reserves at an alarmingly low level, cuts in public spending are the order of the day. The intermediate tiers of government, such as provincial authorities and water control boards, have not escaped the present mania for economizing. Can we do things more efficiently and effectively? In some policy proposals, provincial authorities and the typically Dutch institution of water control boards are to be phased out, and their responsibilities transferred to the national government and local authorities. At the moment, all these parties are still conducting a joint public information campaign under the slogan ‘The Netherlands Lives with Water’. But for how long? And what is one to think of all these developments? In olden times, water management was a task of local government. However, local authorities (or the medieval equivalent thereof) soon realized that working with water is a real profession requiring specific expertise. Over time, polder district authorities and water control boards developed into a distinct and independent tier of government. They were responsible for managing the ‘visible water’ we see
all around us in canals, lakes, rivers, polders and the like. Thus was established the venerable tradition of ‘water control boards’. Now, more than seven centuries later, these boards are also responsible for the waste portion of the water cycle, i.e. the ‘invisible’ water in sewers and pipes beneath our feet. It was only relatively recently that these tasks were assigned to the water control boards and they could be performed much more efficiently, so concluded a recent ‘fact finding’ report which unfortunately failed to address the more systemic aspects of water management. Water control boards have left indelible marks on the Dutch landscape and have contributed greatly to spatial quality in our country. The boards enjoy broad legitimacy and are in an excellent position to place water issues high on the spatial planning agenda. Thanks to a separate tax regime, the necessary funding is relatively secure and the same applies to the required focus on water safety. In that sense, I believe that Dutch water control boards can serve as an excellent model for water management elsewhere on our warming planet, where this most precious resource plays a key role in an array of serious problems ranging from river floods to rising sea levels. In this way, water

control boards also support the export and marketing of a quintessentially Dutch area of expertise and skill. Why endanger the continued existence of venerable institutions that have proven their worth? Aren’t we throwing away a great many valuable things? Our tradition, our heritage, and centuries of experience gained in a country that has always had to contend with the forces of sea and river? Granted, realizing further economies of scale is important. The same goes for a more efficient and professional approach to the tasks at hand. But what is one to think of flip flopping politicians willing to throw out the baby – i.e. the tradition of water control boards – with the bathwater? No good will come of such plans. The ‘infinite plains’ of Marsman’s poem will sleep a great deal easier if water management is left in the hands of people who know their trade. Only then can we ensure that, in the words of the poet, ‘the voice of the water / with its endless disasters / is feared and obeyed’.
