Municipal drinking water for the village of Winchester is blended from four distinct well fields and is comprised of six well heads. The Winchester production wells are owned by the Township of North Dundas and are operated by the Ontario Clean Water Agency (OCWA). This system services a population of approximately 2,300.
Four Wellhead Protection Areas (WHPAs) have been delineated representing differnt times of travel to the well: WHPA-A, WHPA-B, WHPA-C and WHPA-D (travel times of "immediate", 2 years, 5 years and 25 years respectively). The WHPAs have been scored from 2 to 10. The vulnerability score is a representative measure of the drinking water source's susceptibility to contamination. Higher scores indicate higher vulnerability.
