Tips for Pools, Spas, Fountain Owners

Tips for pool owners

The City of Los Angeles allows for the periodic draining of swimming pools, spas and decorative fountains into the gutter, storm drain system or sanitary sewer, provided that certain good housekeeping practices are followed:


  • De-chlorinate or de-brominate swimming pool, spa or decorative fountain water by allowing the water to sit for a few days without adding chlorine or adding a de-chlorinizing agent to the water prior to discharging it to the gutter or sanitary sewer system.

  • Discharges of de-chlorinated or de-brominated water to the storm drain system are allowed between 8:00 p.m. and 8:00 a.m. and to prevent the overload of the sanitary sewer system, please do not discharge pool water until 48 hours after the end of a rainstorm. When discharging to a storm drain, examine the corner catch basin for cleanliness prior to releasing the water. Clogged catch basins may cause the discharged water to flood surface streets. Call (800) 974-9794 to report a clogged catch basin.

  • Pool water containing copper-based algaecides may not be discharged to the storm drain or sanitary sewer system.

  • Pool water containing dyes may not be discharged to the storm drain system. Discharges of dyed water to the sanitary sewer system are conditional pursuant to LAMC 64.30.
