Redundant Water Transmission Main Installation - City of Lewiston

Engineering for this project is underway and is at the preliminary design phase. The project would include a new water transmission main from the lake to Main Street Pumping Station (or where ever the pumping station is located) with a new river crossing at the Auburn Boat Launch to Avon Street in Lewiston. Phase 1 would be to construct a new main on North River Road in Auburn from Center Street to the new river crossing. Phase 2 is the river crossing by directional drilling or dredging. Phase 3 is a new 24-inch main from Avon Street to the Main Street. Phase 4 is new transmission main on Main Street from Bates Street to the Main Street Pump Station. A new pump station near or on Avon Street would be feasible if the existing Main Street Pump Station ever needs to be replaced or moved. The last phase that is not included in this LCIP is to install a second transmission main from the lake to the river crossing. Costs shown here are high ranges for the various phases since the design process has not refined the alternatives, and for now are simply prorated. As March 20, 2023, this project is currently in the FY 2024 - 2028 CIP. Funding for this project is allotted in the city's capital improvement plan for construction FY 2025. A firm timeline has not been established; however, construction is scheduled for Fiscal Year 2025. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
