Storm drains are not the default answer
Storm drains in this area generally run untreated to creeks and eventually to the Colorado River system. Chlorinated or salted water reaching them can kill fish and vegetation, and many municipalities prohibit or restrict it outright.
Where discharge to a storm system is allowed at all, it typically requires water that is dechlorinated, pH-neutral and released slowly enough not to erode anything.
The sanitary sewer option
Many homes have a sewer cleanout that can accept pool water at a controlled rate. This is the cleanest legal path in most cities, because the water goes to treatment.
It has limits. Push too much volume too fast and you can back water up into the house — which is why rate matters more than convenience.
Salt pools change the math
Salt pool water at roughly 3,000 ppm will kill turf, ornamentals and trees if it is dumped on a lawn, and it does not wash out of clay soil quickly.
Never route a salt pool drain across your yard or a neighbor's. This is the single most expensive mistake homeowners make when they try to drain a pool themselves.
Ground and structural risk while empty
Central Texas soils move, and hydrostatic pressure after heavy rain can float a shell or crack it. An empty pool is a temporary state, planned around the weather and the water table, not something to leave sitting over a weekend.
Plaster left dry in direct summer sun can also craze. Timing a drain for cooler weather is not just comfort — it protects the finish.
Drought and refill rules
Refilling is the other half of the problem. Watering restrictions in this region sometimes limit pool filling, and utilities often offer a sewer adjustment for a large fill if you request it before or shortly after — worth a phone call on a 20,000-gallon refill.
Because of all of this, a partial drain is often the better answer. Replacing half the water twice can bring cyanuric acid down without ever emptying the shell.
How we handle it
Drain-to-clean work is planned around discharge location, rate, weather and refill before a hose ever comes out, and the plan gets explained to you first.
Local rules differ by city and change, so the discharge point is confirmed for your address rather than assumed.
