What is a sanitary sewer?

A sanitary sewer is a publicly-maintained pipe, normally with a diameter of at least eight inches, which carries wastewater to a treatment plant. 

A wastewater treatment plant uses physical, biological and chemical processes to clean and disinfect wastewater so that it can be returned to the natural environment, usually at a stream, creek or lake. In our community, the City of Marshall Wastewater Treatment Plant on the southeast side of Industrial Road returns highly treated wastewater to the Kalamazoo River. 

The solid particles separated from wastewater are treated and converted into "biosolids" that are recycled on farmland.
