1. A backflow prevention assembly required by this chapter for control of backflow and cross connections is not installed, tested and maintained; or
2. It is found that a backflow prevention assembly has been removed or bypassed; or
3. An unprotected cross connection exists on the premises; or
4. The periodic system survey has not been conducted. Service will not be restored until such conditions or defects are corrected.
B. Inspection Of Customer's System: The customer's system(s) 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, including violation of this ordinance exist and to audit the results of the required survey (R309-400 of the Utah Administrative Code).
C. Installation Of Approved Prevention Assembly: Whenever the the water purveyor, deems 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
D. Type Of Protective Assembly: The type of protective assembly required under subsection C of this section, 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 resulting from the required survey.
E. Previously Approved Assemblies:
1. 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 subsection 3.1.6, be excluded from the requirements of these rules so long as the water purveyor is assured that they will satisfactorily protect the public water system. Whenever the existing is moved from the present location or, requires more than minimum maintenance or, when the water purveyor finds that the operation or of this assembly constitutes a hazard to health, the unit shall be replaced by an approved backflow prevention assembly meeting all local and state requirements.
2. It shall be the responsibility of the consumer at any premises where backflow prevention assemblies are installed to have certified surveys/inspections, and operational test made at least once per year at the consumer's expense. In those instances where the Public Water Purveyor deems the hazard to be great, he may required certified surveys/inspections and test at a more frequent interval. It shall be the duty of the 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.
F. Testing Backflow Prevention Assemblies: All backflow prevention assemblies shall be tested within ten (10) working days of initial installation.
