From Cleaner Pools to Water Conservation: The Unexpected Discovery Behind AquaRev Water


What began as a search for cleaner pool water may have uncovered a new approach to reducing one of the Southwest's most overlooked water challenges.

When Keith Morrill founded HDC Products, he wasn't trying to solve water scarcity.

Like many pool owners in Hawaii, he was looking for a better way to maintain crystal-clear water without relying heavily on chemicals.

After years of research, testing, and development, he created AquaRev Water, a hydrodynamic cavitation device that improves water quality through naturally occurring pressure changes within moving water.


The original goal was straightforward:

  • Improve water clarity

  • Reduce chemical demand

  • Create a healthier swimming environment


The results exceeded expectations.

But they also revealed something entirely unexpected.

The Observation Nobody Expected

As AquaRev installations increased, pool owners and service professionals began noticing something unusual.

Pools appeared to need less refill water.

At first, it was easy to dismiss.

Weather changes.Usage differences.Coincidence.

Yet the observation continued appearing across multiple installations and climates.

The pools weren't simply cleaner.

They were losing less water.

Why Evaporation Matters

Evaporation is often viewed as a normal part of pool ownership.

But across the American Southwest, the numbers add up quickly.

According to the City of Mesa, Arizona, a standard residential pool may lose approximately 0.35 inches of water per day during summer months.

Over time, that can represent thousands of gallons of water lost annually from a single pool.


Multiply that across Arizona's estimated 500,000 residential pools and the scale becomes substantial.


At the same time, regional water resources face increasing pressure from:

  • Population growth

  • Housing expansion

  • Semiconductor manufacturing

  • Data centers

  • AI infrastructure development


Every gallon matters.


Arizona Field Testing Results

Arizona field testing involving AquaRev Water demonstrated measurable reductions in both chemical consumption and water use.


Results included:


47% Reduction in Pool Water Consumption

Reduced refill requirements suggest significantly lower evaporation losses.


53% Reduction in Chlorine Consumption

Less chlorine demand means lower operating costs and fewer chemical additions.


Reduced Acid Demand

More stable water chemistry translates into less correction and adjustment.


57% Reduction in Phosphate Treatment Consumption

Improved water conditions reduced the need for supplemental treatments.

The Bigger Lesson

No technology alone will solve the Southwest's water challenges.

But meaningful progress often comes from addressing problems we have historically accepted as unavoidable.


For decades, water management has focused on generating more supply.

The future may also require reducing unnecessary loss.


Perhaps the most exciting aspect of AquaRev's story isn't that it helps create cleaner water.


It's that it suggests we may be able to conserve water using principles nature has relied upon for millions of years through hydrodynamic cavitation.


Because every gallon that never evaporates is a gallon we never have to replace.
