At the Town of Cary, we are committed to providing our customers with safe, high quality drinking water. In our effort to do this, the Town Council adopted a Cross Connection Ordinance to ensure the protection of our community’s water system; the Ordinance requires all water system customers to have an approved backflow prevention assembly installed. All backflow prevention assemblies other than single family residential are required to be tested annually. Backflow prevention assemblies are required by the federal Environmental Protection Agency and the State of North Carolina to safeguard water systems.
