If you witness a sanitary sewer overflow (sewer coming out of a manhole) or suspect a main line blockage is causing sewer to back up at your home, contact WMD-Collection System Maintenance at 559-621-1496 immediately. Your call is important to us. To ensure prompt assistance, make sure you talk directly to a City representative. VOICE MESSAGES OR E-MAILS ARE NOT RECOMMENDED.

Staff is available 24/7 to respond to sanitary sewer emergencies. Once on site, WMD will determine if the back-up is a lateral issue or a main line issue. If a lateral issue, the owner is responsible to maintain the property and should call a certified plumber to take care of the problem. If the back-up is caused by a mainline issue, the City will proceed cleaning the line and will assess the cause of the problem and proceed with the necessary repairs, outreach or increase preventive maintenance to minimize future occurrences.

559-621-1496 will connect you with City personnel 24/7 for sewer emergencies.
