This project consists of the following:
1. Repair deteriorated concrete beams and walls in the Evanston Pump Station, replace the pump station roof, abandon unused storage rooms, and replace the bar screen assembly in the influent chamber.
2. Rehabilitate deteriorated concrete channel walls at the Wilmette Pump Station, replace two existing pumps, and convert the remaining two pump tunnels to diversion tunnels.
3. Remove the diversion gate at the Wilmette Pump Station and replace it with a triple gate system.
4. Rehabilitate the west bank sanitary ejection station at the Wilmette Pump Station.
The estimated cost of the project is $25,500,000.00.
Requested, Kenneth A. Kits, Director of Engineering, TEK:ECB
