Storm drains are designed to prevent flooding on the road, in yards, and around homes and businesses. They work by diverting rainwater and melting snow and ice into nearby bodies of water. Every time it rains, water runs off of your roof, through your gutters, and into the street.

Is storm drain and sewer the same?

A: The sanitary sewer system collects water from inside our homes and businesses and carries it to a treatment plant where the wastewater is cleaned before being released into the Delta. Storm drains are located along streets and in parking lots and flow directly to the Delta without treatment.

Who is responsible for storm drain?

Property owners are responsible for maintaining the storm drainage systems, both open and closed, that convey storm water runoff from their private property, while public and private entities maintain the closed water system.
