Conserving Swimming Pool Water During Drought Conditions

Owning a swimming pool in the Southwest United States often leads to problems during the hot summer months.  High temperatures accelerate evaporation, creating elevated calcium levels in the pool from the need to add more water, and thus more calcium. Our fill water is loaded with calcium and other hardness minerals, which can often be problematic for swimming pool owners. We generally suggest that you need to drain a pool once calcium levels exceed 600 ppm, which seems wasteful, especially when water was, and still is, at a premium and drought conditions exist in many parts of the Country.

As of today most of California, Nevada, and Arizona (yes Arizona) are dealing with major drought restrictions and hard water. That is why our mobile filtration system is the perfect solution to not only keep the existing water in your pool but the best solution to recycle swimming pool water instead of draining it. As previously mentioned, swimming pool owners are usually told by pool professionals to drain their swimming pools when their TDS climbs above 3,000 ppm, when CYA is over 100 ppm and calcium is above 600 ppm. This is a reality in the southwest because as the water evaporates due to high temperatures, the minerals concentrate in the water and scale the tile, the interior finish, and can damage filtration equipment.

Draining a pool to address this issue creates a risk of cracking the interior finish and/or raising a swimming pool out of the ground; both costly, if not impossible to repair.

Mobile Reverse Osmosis Trailers To Conserve Water

With that said, we felt that designing a mobile filtration system that could lower TDS, calcium, and CYA, along with correcting other problematic water issues, was a perfect option, as it doesn’t even require a pool to be drained, except to re-plaster. The mobile filtration trailer was designed to filter both commercial and residential pools, and pools can be used during the process. Inside the trailer is a large industrial reverse osmosis system that works on high pressure, thus making water loss extremely minimal (approx. 15%). The trailer is completely self-contained and runs off its own power, and is designed to filter up to 40,000 gallons of water a day. The process is relatively simple: once the trailer is parked onsite, two hoses are rolled out to the pool. The intake hose carries water from the pool into the trailer, where three sets of membranes filter everything out of the water and then return the clean water to the pool through the output hose. Everything is a function of time. The trailer has many different components that make it possible to know, based on the original chemistry of the pool water, the exact amount of run time to filter the pool. This filtration time will allow for setting the chemistry levels at an optimal stage that is better than the tap water provided by your water provider. The end product is actually drinking water!

The “Puripool” Process was designed by Pure Water Industries. to filter nearly any size pool, with any type of surface, and in virtually any condition. This is an excellent alternative to draining pools and saves hundreds of thousand gallons of water in a region where water is at a premium.

The price to filter your swimming pool is slightly higher than a drain and refill, but the end product is much better; not to mention conserving on average nearly 20,000 gallons of water per pool, in about a twelve-hour timespan.
