Water Treatment
All of Culleoka Water Supply Corporation's water is purchased from the North Texas Municipal Water District (NTMWD), Wylie, Texas, through a contract with the City of Princeton. NTMWD takes raw water from Lake Lavon and several other sources and processes it for delivery to a number of cities, water districts and rural water supplies in the surrounding area. Some of wholesale customers of NTMWD, in addition to Culleoka Water Supply Corporation, include the City of Farmersville, the City of Princeton, the Milligan Water Supply Corporation, the City of McKinney, the City of Allen and parts of the City of Richardson.
Treated water is purchased from NTMWD. Culleoka WSC does not provide any additional treatment of the water other than to add a small amount of chlorine, if required. Chlorine is added to maintain the State of Texas required level of chlorination to prevent bacteria from developing which ensures a safe and pure water supply to our customers. Other than chlorine, Culleoka Water Supply does not add any chemicals or treatment processes to the water.
