Frequently Asked Questions:
Important note: If you see or suspect that there is a sewer problem, take immediate action by discontinuing the use of water inside your house or building in order to cease drainage to your sewer lateral. Contact the City of Merced, Public Works Department. City personnel will respond and inform you if the problem is in the City main or if it is in the house or building’s lateral, at which time you should call a plumber.
