As part of its ongoing efforts to enhance the sanitary sewer collection system, First Utility District (FUD) continuously assesses its collection system assets. Recently, FUD concentrated on the Ebenezer sewer basin due to recurrent sanitary sewer overflows (SSOs) at the Ebenezer Pump Station and several manholes along the incoming gravity sewer. Additional concerns included the pump station’s operational and physical condition, its location within the floodplain, and its limited capacity. FUD committed to evaluating alternatives as part of a comprehensive basin master plan to address the SSOs, the aging pump station, and downstream impacts. Various alternative combinations were considered for managing the basin’s flows including: •Rehabilitating upstream sewers to reduce inflow and infiltration (I&I) •Increasing the diameter of the 7,200 linear feet (LF) interceptor from 15” to 20” •Diverting peak flow to a new pump station •Constructing a new station and force main to the wastewater treatment plant (WWTP) •Constructing a new station and a 1-million-gallon (MG) storage tank The detailed evaluation included the development of a sewer model and preliminary engineering report which resulted in the selection and construction of an innovative solution comprising of: •A new 2.3 MGD wastewater peak flow pump station and approximately 7,000 LF of 16-inch force main •A new 5 MGD Ebenezer wastewater pump station relocated above the floodplain and approximately 3,000 LF of 18-inch force main with surge protection tanks •A new 1.5 MG prestressed concrete equalization tank •Associated electrical control buildings and backup generators •A fully automated control scheme that reads gravity sewer levels, operates valves, and calculates influent flows to divert wet weather flows where capacity is available while maximizing the use of existing infrastructure. This solution will significantly reduce the risk of future SSOs and address the operational challenges that have historically affected this sewer basin. The new system will provide FUD with a reliable and efficient infrastructure for years to come. The construction cost of these improvements was $17.5 million and was the largest remote facilities capital project in FUD’s history.
