BY COUNCILOR JOHNSON:
The city of Duluth does ordain:
Section 1. That Chapter 48, Article VI, of the Duluth City Code, as amended, is amended by adding a new Section 48-174 to read as follows:
Sec. 48-174. Cross connection control.
(a) If, in the judgment of the department or building official, an approved backflow prevention assembly is required for the safety of the water system, the department shall give notice to said customer to install such an approved backflow prevention assembly(ies) at specific location(s) on the customer’s premises. The customer shall install such approved assembly(ies), within the time period ordered by the department, at the customer’s own expense; and failure, refusal or inability on the part of the customer to install, have tested and maintain said assembly(ies) shall constitute grounds for discontinuing water service to the premises until such requirements have been satisfactorily met;
(b) The customer’s system should be open for inspection at all reasonable times to authorized representatives of the department or building official to determine whether cross connections or other structural or sanitary hazards, including violation of city regulations, exist;
(c) In the case of premises having (1) internal cross connections that cannot be permanently corrected and controlled, or (2) intricate plumbing and piping arrangements or where entry to all portions of the premises is not readily accessible for inspection purposes, making it impracticable or impossible to ascertain whether or not dangerous cross connections exist, the public water system shall be protected against backflow from the premises by installing an approved backflow prevention assembly in the service line and at the customer’s own expense;
(d) In the case of any premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete in-plant cross connection survey, the public water system shall be protected against backflow from the premises by either an approved air-gap separation or an approved reduced pressure principle backflow prevention assembly on each service to the premises which shall be installed at the customer’s own expense.
Section 2. That this ordinance shall take effect 30 days after its passage and publication.
STATEMENT OF PURPOSE: This ordinance provides authority to the department to order the installation of cross connection control assemblies on water services. Such authority is necessary to protect the public water supply from hazardous backflow. It further authorizes the department to terminate service to customers who fail to protect the public water supply from backflow generated by the premises serviced by the department.
