The Sauk Centre Public Utilities Commission (SCPUC) operates a 0.9 million gallon per day (MGD) wastewater treatment facility (WWTF) that serves the City of Sauk Centre, Minn.
Stricter effluent limits, aging infrastructure, and necessary equipment required the SCPUC to upgrade and expand the existing treatment system. The SCPUC and SEH project team determined there was a need to minimize electric utility costs due to expanding without increasing the lifetime cost of the WWTF. SEH and the SCPUC worked together with the wholesale electrical provider to make energy efficiency a leading consideration in process, equipment, and material selection. Annually, the WWTF will save 645,000 kWh resulting in a savings of $30,000 on their utility bills.
