Properly Preparing Your Pool

Get your pool ready for summer and protect the environment.

Good housekeeping practices for swimming pool maintenance help keep pollutants out of our waterways and protect the environment. Did you know that chlorine and other pool chemicals harm our waterways when they are improperly discharged?

Draining your pool is usually not a great idea, though it is sometimes necessary for repairs or maintenance. If you must drain your pool, here are five easy steps you can follow to properly discharge your swimming pool water:

  1. Shut off the chlorination system or stop adding chlorine.
  2. Hold the water in the pool for at least five days or add a de-chlorinating agent.
  3. Use a pool testing kit to ensure the level of chlorine is at 0.1ppm before discharging the water. Make sure all debris is removed, chemicals are dissipated, and the water is free of any discoloration, mosquitoes, dirt, or algae. The water's pH should be between 6.5 and 8.5 before discharging.
  4. Submit a Non-stormwater Discharge Notification form to the Engineering Services Department before you drain your pool. You can download the form at, or call the Environmental Programs Info Line at (909) 919-2635 with questions.
  5. Drain the pool water through your lawn or landscaped area. The flow should be controlled to prevent erosion problems and keep it from entering your neighbor's property.

Please note that the water from saltwater pools should only be drained to the sewer or hauled away. Check with the Cucamonga Valley Water District for requirements for discharging to the sewer by calling (909) 944-6000.

Please remember: properly dispose of filter and backwash solids in the trash or landscape area, neutralize acid washes before discharging to the sewer, and do not discharge to the storm drain.

Call the Environmental Programs Info Line at (909) 919-2635 if you have any questions.
