The city is responsible for protecting the drinking water supply from contamination or pollution, which could result from improper private water distribution system construction or configuration.
(Ordinance adopting Code)
The following unacceptable practices are prohibited by state regulations:
(1) 
No direct connection between the public drinking water supply and a potential source of contamination is permitted. Potential sources of contamination shall be isolated from the public water system by an air-gap or an appropriate backflow prevention device.
(2) 
No cross-connection between the public drinking water supply and a private water system is permitted. These potential threats to the public drinking water supply shall be eliminated at the service connection by the installation of an air-gap or a reduced pressure-zone backflow prevention device.

No connection, which allows water to be returned to the public drinking water supply, is permitted.
(4) 
No pipe or pipefitting which contains more than 0.25% lead may be used for the installation or repair of plumbing at any connection, which provides water for human use.

The following are the requirements of the city water system and the customer:
(1) 
A signed customer service agreement will be maintained by the city water system as long as the customer or the premises is connected to the city water system.
(2) 
The customer shall allow the property to be inspected for possible cross-connections and other potential contamination hazards. These inspections shall be conducted by the city water system or its designated agent prior to initiating new water service; when there is reason to believe that cross-connections or other potential contamination hazards exist; or after any major changes to the private water distribution facilities. The inspections shall be conducted during the city water system’s normal business hours.
(3) 
The city water system shall notify the customer in writing of any cross-connection or other potential contamination hazard, which has been identified during the initial inspection or the periodic reinspection.
(4) 
The customer shall immediately remove or adequately isolate any potential cross-connections or other potential contamination hazards on his premises.
(5) 
The customer shall at his expense, properly install, test, and maintain any backflow prevention device required by the city water system. Copies of all testing and maintenance records shall be provided to the city water system. All health related premises shall obtain certificates of inspection annually and provide said certificates to the city water system. All nonhealth related premises shall obtain certificates of inspection once every five (5) years and provide said certificates to the city water system.
(Ordinance 287 adopted 4/19/12; Ordinance adopting Code)
If the customer fails to comply with the requirements, the city shall, at its option, either terminate service or install, test, and maintain an appropriate backflow prevention device at the service connection. Any expenses associated with the enforcement of this agreement shall be billed to the customer.
