Madison Metropolitan Sewerage District owns a sanitary sewer pipe that runs down the middle of Lake Mendota Drive. The pipe, which serves the Spring Harbor neighborhood and adjoining areas, is 87 years old and has started to corrode. The district will install a new pipe lining inside the existing pipe from Baker Avenue to Spring Harbor Park using a process called cured-in-place pipe.

Madison Metropolitan Sewerage District maintains a sanitary sewer force main that runs along the east side of Stoughton Road on Madison's east side. A force main is designed to handle pressurized flow (versus gravity flow) and enables wastewater to reach the treatment plant.

The existing force main, installed in 1964, shows signs of corrosion. To extend the life of the pipe, improve flows and prevent groundwater infiltration, district crews plan to install a liner within the existing force main between Buckeye and Cottage Grove roads.
