Pool Water That's Pure Enough to Drink
One of the many benefits of living in Arizona, particularly Central and Southern Arizona, is that we can enjoy swimming in our backyard pools year-round. However, that enjoyment comes with responsibility. As drought conditions continue, we must search for innovative ways to conserve our water resources.
"It is estimated that there are 615,000 residential pools in Arizona," said Rosie on the House Certified Partner, Steve Ward, owner of Arizona Pool Water Recycling. "The average pool holds 15,000 gallons of water of which, three-quarters to an inch evaporates a day."
It is industry standard that homeowners drain and refill their pools every two to three-years to keep the water sanitary. That's a loss of about 29-acre feet of water down the drain. That can be hard to think about during a drought.
In 2015, California placed a moratorium on filling or topping off pools because of the extreme drought. That ban was lifted in March 2019, but with the current conditions, it could happen again. Oftentimes, regulations in California make their way to Arizona. So, if an extreme drought hits us, Arizona pool owners may be faced with the same ban.
The Arizona Republic reported on August 15, 2019, that for the first time, mandatory water cutbacks will begin next year along the Colorado River. Arizona does not currently use its full allotment of water from the Colorado River and next year our allotment will go down by 192,000 acre feet of water a day.
Even if a fill or top-off ban is not placed, it still is a hassle to pump the water from the pool, pay for the refill and figure out the complicated chemicals needed to re-balance the water. Your relaxing, inviting swimming pool becomes more work to maintain and the water becomes less sanitary if you don't keep up with regular maintenance.
Arizona Pool Water Recycling has an innovative alternative to sending a pool's worth of water down the drain that is good for the environment.
Their Puripool™ Process, invented in 2009, allows homeowners to process their swimming pool water through a purification trailer, resulting in conserving water, using fewer chemicals and enjoying a swimming pool that is cleaner, safer and healthier.
"In about a day, we will filter your water and lower calcium hardness, total dissolved solids (TDS), cyanuric acid, phosphates, salt, bacteria, viruses, and more," said Ward. "We will give you back a clean, healthy pool; all while conserving up to 85 percent of your existing pool water. Your pool will be as pure as if you had filled it with bottled drinking water."
The Benefits of Recycling Your Pool Water
"There are countless benefits to you as a pool owner, your family, and the environment, when you choose to recycle your pool water," said Ward.
No damage to the surface of your pool
Exposing the plaster during a drain and refill can cause plaster damage and/or failure, which is an expensive repair. On other occasions, pools have "popped" out of the ground as the water is removed and the pool "floats." Once a pool has popped out of the ground, it will not go back down.
Your family and guests can safely swim while the existing water is processed, leaving you with a clean, healthy pool.
Save time and money
With cleaner, purer pool water, you won't have to spend a lot of time and money on chemicals, trying to balance old, tired and unsanitary water.
Ward explained that when a pool has high cyanuric acid, the pool requires a higher level of chlorine to keep it properly sanitized. As the water ages, the need for more tablets and/or shock will increase. As the chlorine is less effective, the pool may need an algaecide to keep it clean/clear. The less sanitary the water, the more backwashing of the filter is likely to be needed. "It kind of begins a downward spiral," said Ward.
Conserve a valuable and limited resource
Recycling pool water, allows you to retain up to 85 percent of your existing pool water while being a good steward of water resources.
The Pool Water Recycling Process
Test the Water
The pool water is tested for calcium hardness, TDS, pH, chlorine, alkalinity, phosphates, cyanuric acid, and salinity. The results (before and after) are logged on a Chemical Analysis Sheet, which you will receive after the process is complete.
Hoses run from the purification system to the pool for suction and return. On the end of the suction hose, Virginia Graeme Baker (VGBA)-compliant fittings are used for your safety so the pool can be used while the water is being processed. Two garden hoses are also used. One hose supplies water to replenish the small amount (approximately 15 percent) lost in the filtering process. This hose goes from your house to the purification trailer where it is processed before being returned to the pool. The second hose, for waste, gets rid of unwanted solids. This hose goes from the trailer to the sewer line. Most city sewer water is recycled so even that 15% gets recycled since it is not sent down the street.
Calculations based on the pool water's TDS and calcium hardness will determine the set points and run time. Water processing units are self-contained. The technician will bring power and supplies.
Monitoring and Processing
A computer in the unit is linked to the technician's cell phone, notifying them of any interruptions, when the set points are met, and the process is complete.
The water is processed through the proprietary multi-stage filtration system, removing all of the impurities and TDS. The process takes approximately 10 hours per 20,000 gallons.
Completing the Process
Once the set points are met and all of the water has been restored to bottled water purity, the process is complete. The system will then shut down automatically. The technician will return to retest the pool water and pick up the unit.
"In two years, our customers combined have saved several million gallons of water," said Ward. "We recently recycled 33,000 gallons of water from one pool alone. That's 264,000 average-size bottles of drinking water! Imagine wasting that amount of water."
Let's not wait until we are in desperate situation to save our precious water. We are all responsible for lowering usage and conserving water.
