The Frances Park Pump Station sits adjacent to the Grand River and is a cast-in-place structure with a dual-chamber wet well and five existing pumps: three wet weather pumps and two dry weather pumps. The station discharges to the upstream end of the west side interceptor through a 24-inch-diameter force main.
Keeping the existing pump station in operation throughout construction was challenging. A phased construction approach was required where portions of the existing electrical equipment were disconnected and removed to accommodate new equipment installation.
A new bypass pumping manhole was installed to allow temporary bypass of flow during completion of the wet well and electrical equipment improvements.
