All correspondence must be made through the Vendor Portal. Specifications include, but are not limited to: GLWA requests bids from construction companies (“Contractor”) to complete the Freud Pump Station Improvements as summarized in the “Scope of Work” section in accordance with the Specifications and Plans. The Work for the Project shall be performed at the existing Freud Storm Pump Station, and the new Freud Sanitary Pump Station will be located approximately 1.5 blocks east of the Freud Storm Pump Station on Freud St between Conner St. and Navahoe St. The Project aims to make modifications and improvements to enhance the protection of the health, safety, and welfare of residents served by the pump station for the next 50+ years. The Project focuses on improving the operability, reliability, integrity, and maintainability of the station over the life of the facility. The Work includes rehab of the eight stormwater pumps, including replacement of the pump rotating assembly, line shafts, and concrete pump supports, installing new dewatering pumps inside the Freud Storm Pump Station with an approximate 10.8 MGD firm capacity, providing dedicated access to the Freud Storm Pump Station wet well, and construction of a new Freud Sanitary Pump Station approximately 1.5 blocks east of the existing storm pump station. The sanitary pump station will be constructed over the two 16-ft diameter tunnels that convey flow to the existing Freud Storm Pump Station. The structure includes provisions to add stop logs in the two 16-ft tunnels to isolate Freud Storm Pump Station. The stop logs and improved access to the wet well at the existing Freud Pump Station will enable GLWA to isolate the wet well for future cleaning, inspection, and maintenance. The proposed structure will include a sanitary pump station with a firm capacity of 30 million gallons per day to manage dry weather flows. Submersible sanitary pumps will discharge to a proposed 36-inch force main on Navahoe Street connecting to the 9-ft diameter Detroit River Interceptor on East Jefferson. The Project will improve the station's reliability and reduce the risk of collection system surcharging and combined sewage backups into basements.
