The below ground storage tank will hold excessive sanitary sewer flows during rain events
The Village of Wilmette, Illinois held a groundbreaking ceremony at the end of September for the new 5.5 million gallon West Park Sanitary Storage Project. The below ground storage tank will hold excessive sanitary sewer flows during rain events.
The project includes, the storage reservoir backflow valve that will prevent sewerage from the Metropolitan Water Reclamation District (MWRD) from backing up into the sanitary sewer system, and a pump station that will pump sewer flows down stream during heavy rain events.
The project will provide relief to over 1300 homes west of Romona Road by reducing the frequency and severity of sewage basement backups after major storm events.
The excavation of the storage tank began after the groundbreaking and is expected to last between 10 to 12 weeks. The tank is scheduled to be in place by September of 2015. West Park field will be closed for a year and reopen in spring of 2016. The West Park Sanitary Storage Project is a design-build project, with the joint venture of RJN Group Inc. and Boller Construction Co. Inc. serving as the design-build entity.
