Wastewater (Sanitary Sewer) Collection

When sewage leaves a home or business it flows through service lines to the main sewer pipe in the street where gravity keeps it flowing downward. When the main line reaches a depth of 20-30 feet, a sanitary lift station pumps the sewage up to a higher level where the sewage begins to flow again by gravity to a central metering station. Approximately 10.5 million gallons of sewage move out of the city daily through pipes which average six inches to 48 inches in diameter.

From the metering station the sewage flows under the Minnesota River, in a series of three sealed pipes ranging from 30-40 inches in diameter, to the Seneca Wastewater Treatment Plant in Eagan, which is owned and operated by Metropolitan Council Environmental Services.
