Mt. View Sanitary District defines the Sanitary Sewer Lateral or building lateral as typically beginning within two feet of the building structure to where it connects to the mainline sewer. This also includes the fitting in which the lateral connects to the mainline.

The Sanitary Sewer Lateral is also defined by the terms Upper Lateral and Lower Lateral. The Upper Lateral is the portion of the Sanitary Sewer Lateral that is typically installed within two feet of the building structure to the property line. The Lower Lateral is the portion that is installed from the property line to the mainline sewer connection. The entire Sanitary Sewer Lateral is the private property of the building owner who is, therefore, responsible for all costs related to the installation, connection, maintenance, repair, reconstruction, alteration, abandonment, or removal of the Sanitary Sewer Lateral.

Protect your investment by locating your home’s sewer cleanout and installing an overflow protection device. Your cleanout is typically found outside of your home or just behind the sidewalk on your property. This will be a pipe with a screw cap that has a square knob or an indentation on the top.

An overflow protection device, also known as a sewer relief valve or popper, is designed to help you avoid costly repairs or damage caused by a sewage backup. It allows sewage to escape outside the home in the event of a lateral blockage and allows an access point to clear and inspect your lateral. Consult a professional to ensure proper installation and maintenance.

A permit is required for any work performed on your lateral. Permit information can be found at https://mvsd.org/permitting or by emailing info@mvsd.org.

Should you experience a sewer backup or overflow incident, please notify the District 24 hours a day, 7 days a week at 925-228-5635.
