For your pool
What this means for your pool
-
Digging
The main soil here is heaton loamy fine sand, and the soil survey records no rock layer in it. Deep sand digs easier than rock but can slump, so ask how the hole will be held open. [3]
-
Slope and views
The ground within 5 miles rises and falls about 462 feet. Sloped lots often need retaining walls, and the same slope can give a pool a view. [1]
-
Plaster and scale
The city's water averages about 353 ppm hardness, which counts as very hard (over 180). Hard fill water leaves scale on tile and plaster, so test calcium hardness when you fill and top up. [7][14]
-
Covers and top-ups
Open water here loses about 54.7 inches a year to evaporation. That is more than the 30.6 inches of rain and snow a year. A pool cover cuts how often you top up. [6][5]
-
Freeze protection
About 42 nights a year drop to 32°F or below. Run the pump through hard freezes or fit a freeze sensor, and protect exposed pipes at the equipment pad. [5]
-
Fill timing
Your water supplier can limit outdoor water use in a drought. Check the current stage before you drain, fill or refill a pool. [10]
-
Filter care
Ashe juniper (cedar) sheds pollen from mid-December into early March, and oak leaves drop into the water. Empty skimmer baskets and clean the filter more often then. [13]
-
Critters
Scorpions, rattlesnakes, copperheads and chirping frogs all live in this part of Texas. Keep the equipment pad clear of clutter and check before you reach in. [9]
