Flush Green

PROTECTING WATER QUALITY STARTS WITH EACH OF US!

Your drains are not a trash can. The water from your home or business (toilet, shower, kitchen, etc.) ends up into one of the most beautiful parts of our community, the San Francisco Bay.

Throwing anything other than toilet paper down the drains can cause sanitary sewer overflows (SSOs) and will severely impact your plumbing system, the city’s sewer system, and the processes at the treatment plant.

Please take a few minutes to download our "Flush Green" flyer and learn more about properly disposing of waste.
