P23-543 - 3rd Avenue Pump Station Force Main Rehabilitation Project

The Third Ave Pumping Station (TAPS) is the most critical pump station in the City’s system. The collection system in the downtown area of the City drains to TAPS where the flow is pumped to the Water Pollution Control Facility (WPCF). It is located approximately 3.5 miles from the WPCF.

The peak storm flows pumped from the station exceed the nominal treatment capacity of the plant. Flows above the capacity of the plant are redirected to the retention basin on the WPCF site. The station has an overflow to the Flint River which has been activated several times in the past due to power failure at TAPS and force main pipe failure. This results in a sanitary sewage overflow (SSO) which is prohibited under the Michigan Department of Environment, Great Lakes and Energy’s regulations.
 
The City of Flint’s Water Pollution Control Facility (WPCF) is constantly improving its collection system to better serve its customers, and the City has committed to the improvement of the force mains from the Third Avenue Pumping Station as its latest project. This project will be undertaken to improve the City’s ability to effectively pump wastewater that is collected within the City’s sanitary sewer collection system to the WPCF.
