Reclaimed Water Irrigation System

Reclaimed Water Irrigation System

A reclaimed (reuse) irrigation system is utilized at a Golf Course Community for the purpose of residential lawn and golf course watering. The SCADA system we installed monitors and controls various processes. The system incorporates three (3) RTUs located at an Irrigation Pump Station, a Supplemental Well Pumping Station, and a Reclaimed Water Supply Station.

The Irrigation Pump Station RTU monitors a local irrigation wet-well and operates two motorized transfer valves based on activity at the Reclaimed Water Supply Station and Supplemental Well Station via SCADA. An Operator Interface Terminal (OIT) at the Irrigation Pump Station RTU provides local user adjustable wet-well level set-point capability. This can also be accomplished from any of the SCADA workstations.

The Reclaimed Water Supply Station RTU provides the primary source of reclaimed water to the Irrigation Pump Station. This RTU monitors a flow meter and controls the reclaimed transfer valve based on the wet-well level set-points established at the Irrigation Pump Station. The flow is totalized and displayed at the Irrigation Pump Station via SCADA.

The Supplemental Well Pumping Station RTU monitors and controls the well pumps based on the wet-well level set-points established at the Irrigation Pump Station. The well pumps alternate based on pump-run-time allotment monitored by the RTU. Should a failure occur to the wet-well level sensor, a back-up high level float at Irrigation Pump Station is monitored to stop all running well pumps and close the transfer valves.
