The scope of services for the LMRDP Dewatering Pump Station is the design of the P&ID drawings, specifications for the controls and instrumentation. This includes the proposed pump controls, along with the proposed valve configurations and flow monitoring. IDCS worked in concert with the process engineers to ensure that the control descriptions follow the intent of the pump station design. This pump station can split the flow between the Lemay Treatment Plant and the proposed Enhanced High Rate Clarification (EHRC) facility. This station had the added complexity of designing for personnel safety with hazardous gas and oxygen monitoring; we introduced CCTV to provide someone on the topside a visual if there is a person in the pump station depths. The pumps have local pump control panels which house pump protection modules to protect the pumps and motors. The pump station has bar screens to trap the large debris; the bar screens will have automatic bar screen climbers to remove debris build up. Tunnel level will be measured with pressure sensors installed on the header pipe. The pump station will have flow meters, gates, valves, an HVAC system, and fire alarm and security systems which will be remotely monitored. This includes specifications for all instrumentation and control, input/output lists, P&ID plans, coordination with process engineers to ensure the pump station will operate as designed
