As the drought continues to impact many areas of the nation, pool pros are looking for innovative new ways to recycle the backwash from filter cleanings.

The drought that has plagued many parts of the United States in recent years has been nothing short of disastrous. Record low levels of precipitation have led to widespread water shortages, with many states implementing mandatory water restrictions. The situation has been particularly dire in California, which recorded the driest 22-year period in at least 1,200 years, according to a new study.

Recent storms have added to the snowpack in the Sierras which supplies 30% of California’s water. Experts however say that it isn’t enough. While these storms have provided some relief, they are unlikely to have a significant impact on the megadrought that California has been experiencing.

For now, major cities like Los Angeles have managed to avoid instituting measures that would prevent homeowners from filling swimming pools. The problem does however make a good case for backwash recycling as it has a direct impact on water usage.

Study Shows Primary Culprits of Water Loss

A study conducted in 2010 by the California Urban Water Conservation Council looked at ways that water is lost in swimming pools. The study pointed out that the primary causes of water loss in pools are leaks, splash out, evaporation, disinfection, and filter operation.

The topic was certainly a hot-button issue at last year’s Pool Industry Expo in Monterrey, CA. It’s also a reason why products like Best Clear System have suddenly become very relevant to the conversation about water conservation. The system promises to help homeowners save thousands of gallons of water while keeping their pool filters effortlessly clean and helping protect the environment

Recycling Backwash Saves Water

To get a better understanding of what the Best Clear System actually does, we spoke with industry veteran and CEO of Aquos Pools, Harold Tapley.

“In a nutshell, the Best Clear System actually clears the water so you don’t have to dump it on the ground and lose it,” said Tapley.

“When you’re discharging, be it backwashing or when you’re washing the cartridge out, you’re getting salts into our fresh water supply. It’s going into the ground or drain in the street and down to the creeks and streams,” explained Tapley, “that creates a conundrum for our industry because it’s almost like Vegas. What happens in Vegas stays in Vegas. Well, what happens in the backyard sort of stays in the backyard because you can’t really see what’s going on. When you see that big white stain in the gutter from D.E. being discharged or somebody out there hosing a cartridge off in the gutter, that really brings it to your attention.”

“If you’re backwashing, the things that are in that backwash, besides salts and chlorine are metals. Typically it’s copper which is deadly to algae in a pool, of course, but when it enters our ecosystem, it creates a lot of problems,” said Tapley, “the discharge itself typically is just sediments of clay or sand, but it does have some stuff in it that’s not good for the environment.”

Pool Pros Put On Notice

Many pool professionals have already begun getting fined according to Tapley. “Here where I live in the Central Valley, the city has actually hired water patrol police. We need real police, but the water patrol, they’re out. There are huge stiff fines for wasting water and dumping it into storm drains. Improper disposal is costing service techs a ton of money when they don’t do things the right way. At P.I.E. I ran into several guys that told me that they had already been fined up to $1,000 for backwashing cartridges in the street,” said Tapley.

To put the numbers into the proper context, Tapley explained just how much water is used in backwashing filters each year. “A typical backwash for a sand filter is 200 to 250 gallons and it’s recommended to backwash them once a week,” explained Tapley, “that’s over 5,000 gallons a year of freshwater that you have to put back in the pool to replace it. Keep in mind that the skimmer starts grabbing air because the water level drops. So you got to double that. I mean, you’re really talking about 10,000 gallons per pool.”

“When you’re cleaning the filter and you dump a couple of hundred gallons of water onto the ground, you lose that pretreated water,” explained Tapley, “and when you’re putting the fresh water back in, then you got to go right back to your test kit and start readjusting the pool. The service guys realize that every time that they have to put more chlorine in because they just top the pool back up and give it a couple of hundred gallons of water. So that said, I feel like when we have pretreated water that we’re capturing and putting it right back in, that is a savings right there itself. If it is a saltwater pool, of course, then we’re saving the salt water.”
