Pool and Spa Tips

Learn how to make your pool or spa as
water efficient as possible.

A properly managed pool or spa can be an appropriate use of water. Use these tips to help save water and money.

Cover Your Pool

An exposed pool loses an average 50 or more inches of water per year to evaporation. During the hot summer months, you may lose up to 4 inches of water each week.

Pool covers reduce evaporation by 90 percent, limit windblown debris, and conserve energy. The Southern Nevada Water Authority offers a pool cover coupon to help you save money and water.

Protect the Pool From Wind

Wind exposure can increase evaporation in uncovered pools. Plant trees and shrubs that buffer your pool, but won't shed or drop leaves in the water.

Maintain Pool Filters

Wash cartridge filters when your pump operating pressure increases by 10 psi (pounds per square inch). You can wash cartridges on landscape areas since chlorinated pool water is diluted with clean water. Never allow wash water to run into the street.

Manage Water Quality

Test pool and spa water frequently and maintain appropriate chemical balances.

Heat Pool Conservatively

Warmer water means higher evaporation rates. Professionals recommend 78 degrees Fahrenheit as the ideal recreational pool temperature.

Test for Leaks

This four-step bucket test may help you determine if you have a leak or a high evaporation rate.

  1. Turn off the automatic fill valve.
  2. Place a bucket on a step where the bucket rim is at least a few inches above the water line. Place a heavy weight in the bucket and add water until the water level inside the bucket is equal with the water level in the pool.
  3. Leave the bucket and pool undisturbed for several hot days, then compare the water level in the bucket to the water level in the pool.
  4. If the water level in the bucket is noticeably higher than the water level in the pool, you may be losing water to a leak. Contact a pool leak detection specialist.

Drain to the Sanitary Sewer

When you drain your pool or spa to the sanitary sewer, you allow the water to be cleaned and used again, rather than wasted. See our "How to drain a pool" and "Pool draining tips" pages for more information.

If you are on a septic tank, call the Southern Nevada Health District at (702) 759-0660 before you drain your pool.
