Bay City does not provide sewer service to property outside the city limits of Bay City.
The Wastewater System consists of a Collection System and a Treatment Plant.
A private sewer lateral or user line is the pipe that connects the home’s plumbing to the publicly-owned sanitary sewer line, usually located under the street. This crucial pipe carries all of the waste water from the home to the sewer, including everything washed down your sink or flushed down your toilet. From there, sewage is transported to a treatment facility thru the collection system.
The private sewer laterals connect to the public sewer main. The sewer main system collects wastewater from the entire city into the wastewater treatment plant (WWTP).
The WWTP operates under an approved DEQ permit.
