We’re pleased to announce that the City of Sioux Falls and HR Green won the ASCE Eastern Branch Outstanding Civil Engineering Achievement Large Project Award for the Sioux Falls Main Pump Station (MPS). The MPS is the largest wastewater pump station in South Dakota and is a critical infrastructure facility that pumps 90% of Sioux Falls wastewater. This project increased the City of Sioux Falls wastewater collection system capacity in conjunction with improvements to the outfall sewer and Water Reclamation Facility.

Innovative engineering approaches include wet well design, corrosion protection, and electrical switchgear control were incorporated into the design. The Main Pump Station has a peak design capacity of 65 mgd with the capability to increase the flow to 90 mgd, providing additional sewer capacity to accommodate future development and serve Sioux Falls for many years to come.
