Pumping Station 15 Rehabilitation

Madison Metropolitan Sewerage District's new Pumping Station 15 has earned the first Envision Gold Award for sustainable infrastructure in the State of Wisconsin.

About the Project

Pumping Station 15 is a regional pumping station located at 2115 Allen Boulevard about a quarter-mile north of University Avenue in the city of Madison.  It is located in Marshall Park - part of the City of Madison parks system and was placed into service in 1974. Due to its age and anticipated land development in the Pumping Station 15 service area, the district began a major rehabilitation project in 2016.  

The need to replace the 40-plus year old pumps and prepare for future capacity led the district to engage with local leaders, community members and other stakeholders to get feedback on how the construction project could also address other needs at the site. The location, between the City of Madison’s Marshall Park boat ramp and the heavily used City of Middleton bike path along Allen Boulevard, prompted the decision to add public restrooms, two aquatic invasive species boat wash hydrants and a bike repair station. Special design features of the site include permeable pavers, carefully sloped asphalt in the parking lot to direct storm runoff away from the lake and a bio-retention pond to catch water used at the boat washing station.

The pumping station conveys an average of 1.32 million gallons of wastewater per day and now has the capacity to pump 8.8 million gallons per day (mgd), which should meet the capacity needs through the year 2045.
