Your water comes from groundwater sources that are located off Francis Street, Knollwood Drive, Draper Road, and Chickering Drive. Colonial Water Company owns or controls the land around these sources and restricts any activity that could contaminate them. As the water comes from the wells at all the sources, and before it reaches you, the customer, we treat it for low pH to reduce blue/green staining and the corrosion of pipes and fixtures. We also chlorinate the water at the Draper Road pumping station and Picardy station. Colonial Water Company does not add fluoride to the water supply.
