(Ord. 1989-1 § 1(A): prior code § 18-81)
13.16.020 Definitions.
Definitions of terms used in this chapter are those contained in the Colorado Department of Health Cross Connection Manual. (Ord. 1989-1 § 1 (B): prior code § 18-82)
13.16.030 Responsibilities of Public Works and Building Department.
A. Public Works Department. The Glendale Public Works Department has the primary responsibility of preventing water from unapproved sources or any other substance from entering the public water supply system. This responsibility starts at the source of supply and includes all of the water distribution system, including service connections.
The Glendale Public Works Department shall set up the cross-connection control program for the Glendale water system, and maintain accurate records of all inspections, installations, tests, and repairs on all backflow prevention devices.
B. Building Department. The Glendale Building Department shall be responsible for review of building plans and specifications and inspection of the installation of plumbing within structures. This responsibility includes the task of preventing cross-connections from being built into structures within the city.
The Building Department’s responsibility begins at the point that the service line enters private property, except for the water meter and appurtenances, and backflow prevention devices connected to the main service. (Ord. 1989-1 § 1(C): prior code § 1883)
13.16.040 Prevention program requirements.
A. An appropriate backflow prevention device shall be installed on the service line to all new buildings and other new construction. The type of device and installation details shall be determined by the Public Works Director.
B. Whenever a building undergoes remodeling, the Public Works Director may require installation of a backflow prevention device depending on the extent of remodeling and the potential for contamination to the public water supply.
C. Whenever the Public Works Director becomes aware of an existing water connection that is not adequately protected by a backflow prevention device and if he determines that there is a reasonable risk of contamination to the public water supply, installation of an appropriate backflow prevention device may be required.
D. Whenever a fire line or irrigation line is installed or remodeled, installation of an appropriate backflow prevention device may be required.
E. The minimum backflow prevention protection shall be as follows:
1. Domestic or general service tap for buildings up to three stories high - Double check valve;
2. Domestic or general service tap for buildings four stories high or higher - Reduced pressure zone backflow preventer;
3. Fire protection line - Double detector check valve;
4. Irrigation services - Pressure vacuum breaker.
Devices that offer a greater degree of protection may be required by the Public Works Director, depending on the specific application.
F. All backflow prevention devices shall be tested by a certified technician immediately after installation of the device. Testing and recordkeeping shall conform to Sections 13.16.050 and 13.16.060 of this chapter.
G. All costs for the design, installation, maintenance, repair and testing of backflow prevention devices shall be borne by the customer/owner. (Ord. 1989-1 § 1 (D): prior code § 18-84)
13.16.050 Testing and maintenance.
A. At least once per year, it will be the duty of the customer/user at any premises where any backflow prevention devices are installed to have a certified test made of these devices. In those specific instances where the Public Works Director deems the hazard great enough, certified inspections may be required at more frequent intervals.
B. A backflow prevention device shall be repaired or replaced, as necessary, at the expense of the customer/user when the device is found to be defective.
C. All customers/owners shall maintain copies of all tests, and records of all repairs or replacements of backflow prevention devices, and shall provide a copy of each such document to the Public Works Director of the city.
D. The certified technician who performs the test shall obtain a test permit number from the Public Works Director for all tests, and the number must appear on all forms related thereto.
E. All backflow prevention devices shall be sealed by the certified technician performing the test at the completion of the test.
F. The Public Works Department retains the right to test or otherwise inspect the installation and operation of any backflow prevention device, whenever deemed necessary by the Public Works Director. (Ord. 1989-1 § 1 (E): prior code § 18-85)
13.16.060 Recordkeeping requirements.
The customer/owner shall safely store, and keep readily available at the subject premises, a copy of all correspondence with the city regarding backflow prevention findings or requirements, as well as all test reports and maintenance records of any backflow prevention devices covered by this chapter for a period of at least three (3) years after the date of any such correspondence, test report or record. (Ord. 1989-1 § 1 (H): prior code § 18-88)
13.16.070 Enforcement—Right of entry.
The Public Works Department representative assigned to inspect premises relative to possible hazards shall carry proper credentials reflecting his/her authority, and upon exhibiting such credentials he/she shall have the right to enter during usual business hours and inspect any backflow prevention device and inspect all buildings and premises for cross-connections in the performance of his/her duties. This right of entry shall be a condition of water service in order to provide assurance that the health, safety and welfare of water consumers throughout the city’s service area is adequately protected. (Ord. 1989-1 § 1 (F): prior code § 18-86)
13.16.080 Violations—Discontinuance of service.
A. Failure of the customer/owner to cooperate in the installation, maintenance, testing or inspection of backflow prevention devices required by this chapter shall be grounds for the discontinuation of water service to the premises.
B. Water service to any premises may be discontinued by the Public Works Department, after written notification, if unprotected cross-connections exist on the premises or if any defect is found in an installed backflow prevention device, or if a backflow prevention device has been removed or bypassed. Service shall not be restored until such conditions or defects are corrected.
C. Discontinuation of water service may be summary, immediate and without written notice whenever, in the judgment of the Public Works Director, such action is necessary to protect the purity of the public potable water supply or the safety of the water system and/or customers.
