Sewer Lateral Maintenance
What is a Sewer Lateral?
Property Owner's Responsibility
Maintaining Your Sewer Lateral
Everything that is put down a private drain reaches the City sewer. A private sewer lateral which is not properly maintained can cause raw sewage to back up within the residence/building and within the City's sewer system. Unmaintained, cracked, or damaged private sewer laterals can be a contributing cause of Sanitary Sewer Overflows (SSOs). Because both storm drains (which transport rain water and irrigation run off) and sanitary sewers are commonplace throughout the City, overflows from the sanitary sewer can readily reach the storm drains causing sewage to flow into streams, rivers, bays, and eventually the ocean.
Your private sewer lateral should be maintained such that it is free of any roots, grease deposits, and other solids which may obstruct the flow. Do not pour fats, oils, or grease down the kitchen drain. Do not dispose of wipes, feminine hygiene products, paper towels, Q-tips, or diapers in the toilet or sink. Be conscious of where you are planting trees because growing roots can cause damage to sewer laterals.
A plumber can be hired annually to make sure private sewer laterals are clean and free from built up waste. Property owners are encouraged to inspect their private sewer lateral upon transfer (buy or sell) of property and then at least every three to five years thereafter to determine if there are any problems or blockages in the sewer lateral.

Reporting Sewer Overflows
Sanitary Sewer Overflows can pose a risk to human health, the environment, and private property. Sewage spills can come from manholes, cleanouts, outside drains, sidewalks, or ground and landscaped areas around buildings. If at any time you suspect there might be a sewage leak, please, call and report it immediately to (408) 776-7333. The City of Morgan Hill will respond immediately to all SSO reports. Web-based reporting is also available through the California Integrated Water Quality System (CIWQS) Project home page or by clicking on the direct report link below.
