Wheatland Municipal Code Ch. 13.52 Cross-Connection Control

It is the responsibility of the public works department of the city to protect the public potable water distribution system from contamination or pollution due to the backflow or back-siphonage of contaminants or pollutants through the water service connection. If, in the judgment of the director of public works an approved backflow prevention device is required at the city's water service connection to any customer's premises for the safety of the city water system, the director or his or her designated agent shall give notice in writing to the customer to install such an approved device at each service connection to their premises. The customer shall immediately install such device, at the customer's expense. Failure, refusal or inability on the part of the customer to install such device shall constitute grounds for discontinuing water service to the premises until such device has been properly installed.

(Ord. 316 § 1, 1987)

Any backflow prevention device required by this chapter shall be a model and size approved by the public works director. The term "approved backflow prevention device" means a device that has been manufactured in full conformance with the standards established by the American Water Works Association (AWWA) entitled "A.W.W.A. C 506-78 Standards for Reduced Pressure and Double Check Valve Backflow Prevention Devices" and, have met completely the laboratory and field performance specifications of the Foundation for Cross-Connection and Hydraulic Research of the University of Southern California.

(Ord. 316 § 2, 1987)

Prior to the installation of any such devices the customer shall submit to the public works director a statement containing the make and model of the device, location and method of installation of such device for approval.

(Ord. 316 § 3, 1987)

It is the duty of the customer-user at any premises where cross-connection devices have been installed to have certified inspections and operational tests made at least once each year. If in the opinion of the director of public works or his or her designated agent a hazard is great enough, the director may require a certified inspection at more frequent intervals. These inspections and tests shall be done at the customer's expense and shall be performed by the city's public works department personnel. These devices shall be repaired, overhauled or replaced whenever said devices are found to be defective at the customer's expense. Records of such tests, repairs or replacement shall be kept and made available to the city.

(Ord. 316 § 4, 1987)

An authorized employee of the city shall have reasonable access to any premises supplied with water for the purpose of making inspections for cross-connection control, inspections of the water system and water meters upon such premises. Any person who, as owner or occupant of any premises, refuses admittance to or hinders or prevents inspection by an authorized employee of the city may have all water shut off, after service of twenty-four hours' notice of the intention of the city to do so.

(Ord. 316 § 5, 1987)
