Pool
Water
Features.
A waterfall does three things in an Arizona backyard, and only one of them is what you think.
It looks good. It masks the neighbors, which matters more than people expect in Power Ranch or Agritopia or Seville, where the houses are close and the block walls carry sound. And it cools your pool, which is not a marketing claim, it is physics, and it is the reason Arizona pool owners install aerators on purpose.
It also costs you water. We will get to that, because nobody else will tell you.
Stay Fresh Pools builds and repairs pool water features across Queen Creek, Gilbert, Chandler, and San Tan Valley.
No task
is too big for us
What We Build
Sheer descents. The clean, flat sheet of water falling from a raised wall or bond beam. Modern, architectural, and the most photographed feature in the category for a reason. Comes in widths from about a foot to six feet, and the effect scales with the drop.
Scuppers. Water pouring from a wall opening or a spout, usually in a set of two or three. More traditional than a sheer descent, and they pair well with tile or stone on the raised wall.
Rock waterfalls. Natural or artificial stone, built up into a fall. This is the classic Arizona backyard look and it works because it belongs in a desert landscape in a way a formal fountain does not.
Grottos. A cave behind or beside the waterfall, sometimes with a bench or a spa inside it. The most involved thing on this list and the one that changes a backyard the most.
Bubblers. Low, gentle mounds of water on a tanning ledge or Baja shelf. Quiet, safe around small kids, and the cheapest way to add movement to a pool.
Deck jets. Arcs of water shooting from the deck into the pool. Dramatic at night with lighting, and they take up no space in the pool itself.
Spa spillways. The water falling from a raised spa into the pool. If you have a spa, you already have a water feature, and it is usually the one that needs the most attention.
The Part Nobody Puts on Their Website
Water features increase evaporation. Meaningfully.
That is the whole mechanism. A waterfall works by breaking water into a thin sheet and exposing it to the air, and in a desert, air is exactly what takes water away. Low humidity, high heat, and wind, which is the precise combination that pulls the most moisture out of an exposed surface.
And Arizona pools already lose a lot. According to the Arizona Department of Water Resources, a standard uncovered pool here loses roughly four to six feet of water per year to evaporation, most of it in summer. Add refilling and backwashing and that is close to the equivalent of filling your pool once a year, every year.
A water feature running constantly in July adds to that.
Every source that quantifies the increase disagrees with the others, and the estimates run from single digits to more than half, so we are not going to give you a number we cannot stand behind. What is not in dispute is the direction, and that it matters more here than anywhere else in the country. Evaporation rates in Arizona run several times what they do in a humid state.
Here is why we are telling you anyway. More evaporation means more top-off, and every gallon of East Valley top-off water brings calcium and dissolved solids with it. That accelerates the cycle that eventually forces a drain and a chemical wash. It is not a reason to skip the waterfall. It is a reason to run it on a schedule instead of leaving it on.
The Flip Side, Which Is Actually a Feature
Now the good news, and it is the same physics.
That evaporation cools your pool. Every gallon that evaporates carries heat away with it, which is why swamp coolers work in Phoenix and not in Houston. Dry air is the whole reason.
In this valley, that is not a footnote. A pool sitting at 92 or 94 degrees in July is not refreshing, it is a bath. Arizona pool owners buy dedicated aerators specifically to fix this, and an aerator is a water feature with the styling removed.
So your waterfall is a cooling system you already paid for. Run it overnight in summer and you will feel the difference in the morning. That is the single best piece of advice on this page and almost nobody gets told it.
Which gives you a simple operating rule:
- Summer: run features overnight for cooling, keep them off during peak afternoon heat when evaporation is highest and the cooling benefit is lowest.
- Winter: run them when you are outside enjoying them, and not much otherwise, because you are shedding heat you may be paying a heater to add.
Automation makes that automatic. Without it, you are the schedule, and most people default to leaving it on or never turning it on at all.
What They Do to Your Tile and Stone
Water features scale faster than anything else in your yard. Hard water plus constant flow plus evaporation right at the point of aeration equals calcium building where the water runs. A spa spillway or a sheer descent lip will grow a scale line while the rest of your pool looks fine.
It is not a defect and it is not neglect. It is what hard water does when you run it over a surface all day. But it means your feature needs tile cleaning more often than your waterline does, and it is worth budgeting for rather than being surprised by.
Two things reduce it: running the feature on a schedule instead of continuously, and keeping your water balanced so calcium stays in solution instead of coming out of it.
When It Stops Working
We repair features too, and here is what usually goes wrong.
Flow has dropped and the sheet is broken or uneven. Usually a scaled or partially blocked feature, sometimes a valve, sometimes a filter restricting the whole system. A sheer descent needs consistent flow across its full width or the effect falls apart.
Water loss only when the pump is running. This is a useful diagnostic. If your pool loses water while the equipment runs but holds level when it is off, that points at pressure-side plumbing or the feature itself, not general evaporation. Worth chasing.
The feature will not turn on. Valve actuator, automation relay, or a manual valve someone closed and forgot.
Staining and calcium build-up on the lip, the rock, or the spillway tile.
Cracked or settled rock work, which is a bigger conversation and needs looking at.
