The Madison Metropolitan Sewerage Department is building a new addition to the sewer system in northeastern Madison. The project will insert a new interceptor line that will help manage the flow of sewage.
The interceptor would be built next to Reindahl Park, close to East Washington Avenue. East Washington itself will remain open during the entire construction period, but Lien, Bartillon, and Rieder roads will be closed until next Summer.
Michael Mucha, the Chief Engineer and Director of the Madison Metropolitan Sewerage District, says this is necessary because the current system is insufficient.
“As there is more growth, we are serving a large and larger area, and we plan our infrastructure to accommodate growth that is expected,” says Mucha.
He adds that this pipe has been in the works for about seven years now.
The 2010 U.S. census placed Madison’s population at around 230,000 people, and current estimates put it at almost 260,000. This has strained existing infrastructure, which is already old and decaying. A statement from the Sewerage District says that quote “a robotic inspection of the 50-year-old pipe revealed corrosion of the interior concrete surface.”
Mucha says that if this project is not installed, sewage could start leaking out.
“We would not have adequate capacity to serve our growth areas. If we had too much flow we would have overflows in the sewer. We’d have raw sewage discharging out of the city and into our water bodies,” Mucha notes.
Mucha added that in addition to installing the new piping, the Sewerage District would also fix the existing pipes by coating the existing pipe. In ten years, this sewer will serve about 60,000 people across Madison, Waunakee, Cottage Grove, DeForest and Windsor.
Before construction could begin, the Madison Metropolitan Sewerage District had to bring the plans before city committees, where they were reviewed and altered. A blog post on the city of Madison’s website said that public officials worked to quote “protect specimen trees, provide a path system that was a valuable asset to the park, and to avoid placing the line further into the park than necessary.” The Madison Board of Park Commissioners approved the final plan unanimously.
The plan will cost an estimated seven million dollars and is expected to finish next Summer.
