Emergency Sewer Calls
For a sewer emergency 24/7: Call (925)228-5635
If you are reporting a sewer backup or overflow incident, please notify the district, 24 hours a day, at (925) 228-5635. The district’s on-call staff will respond to the reported sanitary sewer incident after hours. Please follow phone message prompts for sewer emergencies.
When speaking with a District Representative, please have the following information ready to expedite the response: Name, Address, Phone Number, Address or location of the overflow and all conditions you are experiencing.
If you are experiencing a backup into your home please remain calm, remove all persons and pets from the area. If sewage has overflowed inside the home, shut off all heating and air conditioning (HVAC) units. Do not attempt to remove any affected items from the area. If the Mt. View Sanitary District is found to be responsible for the incident, we are committed to cleaning and restoring your property, and to protecting the health of those affected during the remediation process.
