Plugged sewers and blocked pumps cause backups in the sewer system and it can happen at any time- 2:00am, weekends, holidays, etc. TCSD sewer crew works tirelessly to prevent it- performing video inspections of the sewer, finding spots where tree roots are growing through the pipe and where kitchen oil and fat have accumulated to form a partial blockage that could cause an overflow into the homes and creek nearby.

What can you do to help?

• Only flush the 3 P’s (pee, poop, toilet paper), no other items should be flushed. Even items marketed as flushable are not compatible for the sewer system.
• Fats, Oil and Grease (F.O.G) do not go down the kitchen drain. Make sure to wipe out oil or fat from your pans with a paper towel and throw it in your green cart. For larger amounts, collect your cooking oil and call TCSD to make a drop-off appointment at (415) 388-6393. We can also mail a grease collection container to residents upon request.
