(A) It shall be the responsibility of the customer to conduct, or cause to be conducted, periodic surveys of water use practices on the customer’s premises to determine whether there are actual or potential cross-connections in the customer’s water supply system. The Water Commissioner shall have the authority to conduct, or cause to be conducted, periodic surveys and investigations, at a frequency determined by the Water Commissioner, of water use practices within a customer’s premises to determine whether there are actual or potential cross-connections to the customer’s water supply system through which contaminates or pollutants could backflow into the public water supply system. The Water Commissioner may conduct these surveys, including written information forms, to determine what level of protection will be necessary to protect the public health and safety.
(B) The Water Commissioner shall have the right to enter a premises served by the public water supply system at all reasonable times for the purpose of making surveys and investigations of water use practices within the premises. The Water Commissioner shall give notice thereof setting forth a proposed date and time to the customer at least ten days in advance. If the customer cannot make the premises available for inspection at the proposed date and time, the customer shall contact the Water Commissioner and arrange for another date and time of the inspection. If the Water Commissioner and the consumer cannot agree on a date and time, the Water Commissioner shall treat the premises as if no appropriate cross-connection survey has been completed, and the consumer shall be required to install an approved backflow prevention device.
