Residential Sewer Problems

To report a sewer problem, please call:

Monday - Friday
8AM - 4PM
960-8100
Outside Business Hours 960-8160

What should you do when your toilet, tub, or other drain in your house is draining slowly, or has stopped altogether?

If the problem appears to originate outside the house, call the Water Resources Division (see numbers to the right) prior to calling a plumber. Water Resources staff will be dispatched to check the main sanitary sewer line at no cost to you. The inspection information may be useful  to you should you need to call a plumber.

What Is the Customer's Responsibility?

The connection from the house to the City's main sanitary sewer line (sewer main) is called a sanitary sewer service lateral (sewer lateral). It is the customer's responsibility to maintain, repair and replace their own sewer lateral from the house to the point of connection with the sewer main. All problems on private property are the responsibility of the customer. If your plumber is unable to restore service, call the Water Resources Division while the plumber is still on site, if possible.

What Is the City's Sewer Lateral Program?

Effective July 1, 2000, the Livermore City Council approved a Sewer Lateral Program for residents of single family homes that addresses the cleaning, maintenance and repair of sewer laterals that have a curbside two-way lateral cleanout.

For Homes With a Curbside Two-Way Lateral Cleanout

  • If the problem is determined to be in the sewer lateral within the public right-of-way (area between the property line and sewer main), the City will clean the lateral at no charge to the resident.
  • If the problem is determined to be between the house and the two-way cleanout, it is the customer's responsibility to correct the problem.
  • Replacement of the sewer lateral between the house and the sewer main is the customer's responsibility.

For Homes Without an Approved Curbside Two-Way Lateral Cleanout

two-way cleanoutIf a property's sewer lateral does not have a two-way cleanout, clearing a stoppage requires additional plumbing work that will not be performed by the City. Residents are encourage to install a curbside two-way lateral cleanout. This will allow the City and plumbers to maintain the sewer line.  A cost-effective time to install a cleanout is when a plumber is already repairing or replacing a deteriorated or root-damaged lateral. Replacement of the sewer lateral between the house and the sewer main is the customer's responsibility. Before replacing a sewer lateral or installing a two-way cleanout, the plumber is required to first obtain a permit from the City's Permit Center. The permit is required to ensure the sewer lines and cleanouts are properly installed. Call the Permit Center at 960-4440 for more information.
