The project consists of replacing an existing pump station with upgraded facilities and added flood protection measures.

Influent Gravity Sewer

75 LF

New Force Main

300 LF

Project Details

Part of the Environmental Protection Agency (EPA) Rehabilitation Action Plan – Phase II, the project will rehabilitate the Washington District Pump Station to meet the 100-year flood plain and will need to raise the finished floor to meet this by 2070. The existing building will be removed, and water-tight hatches will be installed over the dry pit submersible pumps. The intermediate wall between the existing dry well and wet well cannot be removed due to the wall being a bearing wall for the pump station. A separate control building will be constructed to meet the floodplain. The replacement of the existing pump station includes elevated above-grade control and generator rooms at elevation 11 with additional protection to elevation 16, below-grade wet and dry wells, a relocated platform for emergency generator to elevation 15, approximately 75 LF of influent gravity sewer, and approximately 300 LF of new force main from the pump station to the existing on-site interceptor force main.
