Pools, Spas, & Fountains – City of San Diego Guidance
Draining a swimming pool, spa or fountain can result in pollutants like algae, chlorine, salt and other chemicals in the water that can be hazardous to San Diego residents and toxic to the environment. Those pollutants and any pool construction materials must be removed before water enters the storm drain system.
