Conveyance Design for Redundancy and Capacity Using Overlapping Pumping Stations

Consolidation and regionalization of wastewater pumping and treatment facilities is common practice, sometimes combining several existing smaller facilities into fewer or even single, larger facilities when practical. However, in some cases, collection system characteristics or facility site limitations can prevent consolidation or expansion of existing facilities, and new, parallel facilities must be considered in order to provide relief. The Madison Metropolitan Sewerage District's Eastside collection system has capacity limitations and hydraulic bottlenecks. In order to provide additional capacity, relief sewers will be constructed and a new, redundant pump station will be built to complement existing pumping facilities.
