The owner or official custodian shall be responsible for protection of the public water supply system from contamination due to backflow or back-siphonage of contaminants through the customer’s water service connection. If, in the judgement of the Maintenance Supervisor or his or her authorized representative, an approved backflow prevention device is necessary for the safety of the public water supply system, the Maintenance Supervisor shall give notice to the consumer to install such approved backflow prevention device at each service connection to the premises. The consumer shall immediately install such approved device or devices at his or her own expense; failure, refusal, or inability on the part of the consumer to install such device or devices immediately shall constitute grounds for discontinuing water service to the premises until such device or devices have been installed. The consumer shall retain records of installation, maintenance, testing, and repair as required in § 50.56(D)(4) below for a period of at least five years. The Maintenance Supervisor may require the consumer to submit a cross-connection inspection report to the (name of public water supply) to assist in determining whether or not service line protection will be required. All cross-connection inspections shall be conducted by a cross-connection control device inspector certified by the state’s Environmental Protection Agency.
