Adopt a Drain Program

Adopt-A-Drain Program

Participate in the City of San Mateo’s Adopt-A-Drain program by taking an active role in improving your neighborhood and keeping our bay clean and free of debris.

Why Adopt-A-Drain?

Everyone knows trash is no good for our streets or our bay, but many of us are unaware of the ways we contribute to pollution. Natural debris-- including leaves, grass clippings, fertilizer, and pet waste -- turns into pollution once it hits the water. The rain washes anything that’s on streets and paved surfaces down storm drains and into the bay. Adopt-A-Drain to help keep our water clean and to prevent flooding on the streets!

Participating is as easy as 1-2-3. 

Claim your drain, pick up city-provided supplies, and clean your drain(s). Find drains to adopt near your home or work and encourage your neighbors, friends, and family to help. A little volunteer effort goes a long way in helping protect our waterways and the environment.
