Water and Wastewater Pump Station Switchgear RFQ Guide

RFQ inputs for MV supply, RMU, LV switchboards, MCC, PLC pump controls, VFDs, soft starters and SCADA interfaces.

Prepared by: JCON ELECUpdated:

Short answer

Start a water or wastewater RFQ with the single-line diagram, pump/motor schedule and control narrative. Separate distribution boards, MCC starters and PLC/SCADA interfaces; specify duty/standby operation, starting method and site environment. Pumps, instruments, process design and commissioning are included only when the quotation explicitly says so.

Define electrical supply and pump-control requirements together

Water treatment plants, wastewater plants and pumping stations combine distribution with process controls. List equipment quantities and interfaces by system so suppliers can price the same scope.

  • MV switchgear or RMU for incoming supply, metering, protection and transformer feeders.
  • Transformers and LV boards for the main bus, outgoing feeders, auxiliaries and compensation.
  • MCC and pump controls with PLC, VFDs or soft starters, including duty and standby functions as specified.
  • Local HMI, telemetry, alarms and SCADA interfaces only as defined in the project requirements.

Frequently asked questions

Which electrical equipment may a pump-station package include?Depending on the SLD, it may include MV switchgear or RMU, transformers, LV main boards, MCC, PLC pump-control panels, VFDs, soft starters, ATS and communications. Confirm the exact scope in the offer.
What information is needed for a pump-control cabinet RFQ?Provide motor ratings and quantities, duty/standby operation, starting method, control narrative, I/O, level/pressure signals, interlocks, protocol, required brands, IP rating and environment.
Does a PLC cabinet quotation include plant SCADA and pump commissioning?Not automatically. Programming, HMI/SCADA integration, field instruments, pumps and site commissioning must be identified and priced within an agreed responsibility schedule.
