Storage Tunnel Reduces SSOs
Design for Milwaukee Metropolitan Sewerage District's 21-foot diameter, 300-foot deep, 27 million gallon tunnel, the North 27th Street Inline Storage System. The project cost-effectively reduces separate sewer overflows for the district. Because the tunnel is integrated with existing deep tunnel storage systems, it also provides the district with the improved operational flexibility in dealing with high flow events.BC led the $65 million two-mile long deep tunnel design to support Milwaukee's $1 billion Overflow Reduction Plan.
