A. No service may be allowed from the city water mains to any premises supplied by water from other source unless the city manager grants permission; and the city manager may terminate such permission at any time. The city manager shall have power to prescribe reasonable regulations for the use of water from another source on premises that have a connection with the city water system.
B. It shall be unlawful for any person, firm or corporation to cause a connection to be made or to allow one to exist for any purpose whatsoever between the city water supply and any other source of supply. Every person, firm or corporation having any other source of water supply upon his or its premises is required to make a customer's declaration of nonexistence of cross connection upon a form supplied by the water department before he or it shall be permitted to obtain or continue to use water from the city water system. City water shall be discontinued upon any premises upon which there is found to be a connection between the city water supply and another water supply; and such service shall not be restored until such cross connection has been discontinued. (2010 Code § 19-19)
