After moving to Dripping Springs in 2014 to raise their family, Trisha and Bill Hall quickly fell in love with the Hill Country lifestyle, including spending long summer days by the pool with their two children. What they did not love was learning that maintaining a healthy swimming pool in Central Texas often meant draining tens of thousands of gallons of water every few years.
That realization eventually led the Halls to launch Aqua P.R.O., a family-owned company built around a simple, but increasingly important, idea: Stop draining pools and start restoring the water already in them.
In a region where drought restrictions and rapid growth continue to strain water supplies, Aqua P.R.O. is introducing many Hill Country homeowners to mobile reverse osmosis filtration, a process that cleans and restores pool water instead of replacing it. Using specialized equipment mounted inside a trailer, the company removes contaminants such as excess calcium, cyanuric acid (CYA), and dissolved solids while conserving up to 85 percent of a pool’s existing water.
The idea for the business began in the Halls’ own backyard.
“We’re pool owners ourselves,” Trisha explains. “A few years ago, we started having water quality problems. The pool was turning green, and we found out we had really high cyanuric acid levels.”
High CYA can create what pool professionals refer to as “chemical lock,” preventing chlorine from properly sanitizing the water. The traditional solution is often partial or full draining, a process that can waste 20,000 to 30,000 gallons of water at a time.
The Halls initially tried partially draining their pool, but the problem persisted. Searching for alternatives, they discovered a reverse osmosis pool treatment service near Georgetown and decided to give it a try.
“The water quality afterward was incredible,” Bill says. “It fixed the CYA issue completely.”
What surprised them most was how uncommon the service was in Central Texas, despite years of drought concerns and increasing pressure on local water supplies. The couple contacted a manufacturer that builds mobile filtration trailers, waited months for a custom system to be completed, and launched Aqua P.R.O.
Now in its second year, the company estimates it has already helped conserve roughly 2.5 million gallons of water.
The process works similarly to reverse osmosis systems commonly used for drinking water. Aqua P.R.O. brings a mobile filtration trailer directly to a customer’s home and continuously circulates pool water through multiple filtration membranes, returning cleaner, balanced water back into the pool. Most treatments can be completed in about 10 to 12 hours without requiring homeowners to drain their pools.
The service has become especially valuable in the Texas Hill Country, where naturally hard water creates ongoing maintenance challenges for pool owners. Elevated calcium levels can lead to scaling that damages pumps, heaters, salt systems, and filtration equipment over time. Reverse osmosis treatment not only helps extend the lifespan of pool systems, but it can also reduce the amount of chlorine and chemicals needed to maintain healthy water.
The process has also become an important solution for fiberglass and prefabricated pools, which can sometimes sustain structural damage if completely drained.
Although reverse osmosis pool treatment has been widely used for years in drought-prone states such as Arizona and California, awareness in Texas is still growing. That is beginning to change as more homeowners search for environmentally conscious ways to maintain their pools.
Customer response across Dripping Springs and surrounding communities has been strong, particularly among residents looking for long-term maintenance solutions that align with the region’s growing focus on sustainability and resource conservation.
As Aqua P.R.O. continues to grow, the Halls hope their company will help change how Texans think about pool care, especially in a region where every gallon matters.
“If people remember one thing, we hope it’s this: Don’t automatically drain your pool,” Bill says. “There’s a better option now. You can fix the water problem and conserve water at the same time.”
