Only Flush the Three Ps:  Pee, Poop and Toilet Paper!

Garbage Belongs in the Trash, Not the Toilet!

Your drains are not a trash can. The water from your home or business (toilet, shower, kitchen, etc.) gets treated and 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 severely impacts your plumbing system, the District’s sewer system, and the processes at the treatment plant.

Properly disposing of your waste will help protect public health and the environment.

Flush only toilet paper in the toilet!
