Only Rain in the Storm Drain!Screen Shot 2014-07-23 at 3.06.51 PM

The storm drain system is designed to protect you from floods and enhance water resources, but the system can be abused by careless disposal of harmful chemicals, wash waters, and other substances.  It is illegal to release anything other than storm water and irrigation water to the storm drain system!

We will visit the location, contact the responsible party and provide information about proper disposal.

Draining a Swimming Pool

Before you drain a swimming pool to the street, you must allow 24-48 hours after the last treatment for all chlorine to dissipate. Contact the District before you drain your pool at (559) 456-3292. If you live in the City of Fresno or Clovis you may need to get a permit before you drain. Use the links below for more information.
