Public Sanitary Sewer System
The Public Sanitary Sewer System consists of nearly 760 miles of gravity pipe connected by 20,000 sanitary access structures and is supported by 29 pumping stations. The City of Madison Engineering Division is responsible for operating and maintaining this system to safely convey 23.6 million gallons of raw sewage per day from Madison homes and businesses to the Nine Springs Wastewater Treatment Plant. Maintaining this system in good operating conditions is essential to the health of our citizens and environment.
Private Sanitary Sewer Service
As a homeowner you are responsible for the maintenance and repair of the private sanitary sewer service line. Your private sewer service extends from within your home to the point where it connects to the public sanitary sewer main.
