IDCS was selected by AECOM to assist in the electrical and control design of an effluent water pump station for the MWRDGC Stickney WRP. The pump station was to supplement the supply of treated effluent that was reused for non-potable water applications throughout the plant.
The pump station consisted of 4 (5 future) 125 HP pumps with anti-surge discharge valves drawing water from an effluent channel and discharging to the effluent water distribution system. The system was connected to an elevated storage tank. The pumps were started by a solid state soft starter.
Control of the pumps was via a local DCU connected to the plant DCS system through a fiber optic backbone. Flow and pressure of the pump station were monitored by the DCS, and pumps started and stopped based upon the elevated storage tank level.
