(1) No water service connection to any premises shall be installed or maintained by the water purveyor unless an approved backflow assembly protects the water supply.
(2) The customer's system shall be open for inspection at all reasonable times to authorized representatives of the water purveyor to determine whether cross connections or other structural or sanitary hazards exist (including violation of this ordinance), and to audit the results of the required survey.
(3) Whenever the public water purveyor deems that a service connection's water usage contributes a sufficient hazard to the water supply, an approved backflow prevention assembly shall be installed on the service line of the identified consumer's water system at or near the property line or immediately inside the building being served, but in all cases, before the first branch line leading off the service line.
(4) The type of protective assembly required under Section (3), shall depend upon the degree of hazard which exists at the point of cross connection (whether direct or indirect), applicable to local and state requirements or resulting from the required survey.
(5) All presently installed backflow prevention assemblies which do not meet the requirements of this Section but were approved assemblies for the purposes described herein at the time of installation and which have been properly maintained, shall, except for the inspection and maintenance requirements under Section (6) below, be excluded from the requirements of this rule so long as the water purveyor is assured that they will satisfactorily protect the public water system. Whenever the existing assembly is moved from the present location or requires more than minimum maintenance, or when the water purveyor finds that the operation or maintenance of this assembly constitutes a hazard to health, the unit shall be replaced by an approved backflow prevention assembly.
(6) It shall be the responsibility of the consumer at any premises where backflow prevention assemblies are installed, to have certified inspections and operational tests made at least once per year at the consumer's expense. In those instances where the water purveyor deems the hazard to be great, he/she may require certified surveys/inspections and tests at more frequent intervals. It shall be the duty of the water purveyor to see that these tests are made according to the standards set forth by the State Department of Environmental Quality Division of Drinking Water.
(7) All backflow prevention assemblies shall be tested within ten (10) working days of initial installation. The owner shall notify the City within twenty-four (24) hours of installation of the backflow prevention assembly.
(8) No backflow prevention assembly shall be installed so as to create a safety hazard. Example: Installed over an electrical panel, steam pipes, boilers, pits, or above ceiling level.
