The South Hill Drainage Project, was a massive project located in Pierce county Washington, comprised of 5 large drainage ponds that cascaded from on to the other until reaching the main pond with The Hemlock Ponds pumping station.† Each motor section of the M.C.C. has independent control of a 150HP pump, with built in safety circuits (Overload, Phase loss, Thermal motor cutout, alarms for pond level cutout), and all the control logic for itís pump to operate.† Then We added a control panel with a US Filter D620i triplex controller at it heart, for automatic operation and monitoring of station operation.† All building and site functions were routed into out M.C.C. and Master control Panel. Alarm conditions for the station were routed into an on-site Annunciator as well as a S.C.C. telemetry unit built for Pierce County in Washington state.† All functions of this station are monitored from the countyís main office, and crews can be dispatched at a moments notice if any station failure occurs.† S.C.C. worked very closely with county engineers, as well as on site contractors to provide a well operating station, that keeps homes and people safe from flooding that had previously caused much grief for residents in the area.

Into S.C.C.ís† Master Control Panel to insure when the power goes down the station stays operational, and informs the county of the power issue immediately so that repairs can be started as soon as possible.
