Pumping Station 15 Sustainable Rehabilitation

The Madison Metropolitan Sewerage District retained Baxter & Woodman to design and construct sustainable improvements to upgrade the condition, capacity, and reliability of the 40-year-old Pumping Station 15. The improvements included:

• Increasing the station’s design capacity for average daily flows and firm pumping capacity
• Installing new pumping equipment, pipes, valves, and appurtenances
• Installing new HVAC, electrical, and control systems
• Installing new flow monitoring equipment in exterior vault
• Constructing a building addition

Green infrastructure elements of the project included:

• Green roof
• Permeable pavers
• 8 kW solar panels
• Bio-swale
• Two bio-infiltration basins

Permeable pavers were installed along a new bike trail segment to encourage bio-infiltration. Native plants treat storm water runoff from the parking lot and the Pumping Station. A three-year plan was included for maintaining plantings in the sustainable features.

In 2018, the project was awarded an Envision Gold Award by the Institute for Sustainable Infrastructure to recognize work that went above and beyond to deliver improvements to the social, economic, and environmental conditions of the community. The project’s performance was assessed across 60 sustainability criteria addressing a wide range of indicators including: community, quality of life, management, planning, materials, energy, water, environmental impacts, emissions, and resilience.
