Greensville County Water and Sewer Authority (GCWSA), established in 1978, currently services nearly 7,000 customers with approximately 1,750 service connections. GCWSA also, in coordination with others, services Dominion Power’s $1.3 billion Greensville County Power Station. The facility powers 400,000 homes in Greensville and Brunswick Counties. This facility’s water demand is extensive, critical to operations, and has very little margin for error with respect to service interruptions.
GCWSA makes water through four surface water treatment facilities strategically located around the county. In recent years a 1 billion gallon raw water storage reservoir and three potable water pumping stations were constructed to help sustain demand.
In 2016, GCWSA began making considerable efforts to eliminate extended down times and a lack of system support caused by a functionally obsolete PLC-based system. The result of these efforts was a monumental and economical upgrade to the authority’s SCADA control system by selecting Dorsett Controls as its new provider.
Dorsett Controls currently services Three Creeks Wastewater Treatment Facility, Jarratt Water Treatment Facility, the authority’s water distribution system, and portions of the wastewater collections system. Additionally, GCWSA is currently installing Dorsett’s SCADA solution at the Skippers Wastewater Facility.
Dorsett Controls’ reliability, functionality, 24/7 support, and extremely low cost of ownership has allowed GCWSA to reduce its maintenance costs tremendously. The SCADA system that Dorsett built and delivered is a platform that Greensville County can build on for years to come.
