The Town shall have the authority to control all service connections within the Town s water system if the connection is a cross-connection. C. The Town may control any service connections within the Town s water system in lieu of a survey as long as the service connection is controlled with an air gap or reduced pressure zone backflow prevention assembly. D. The Town shall maintain records of cross-connection surveys and the installation, testing and repair of all backflow prevention assemblies installed for containment and containment by isolation purposes : APPLICABILITY: This Chapter applies to the following classes of uses of the Town s water system: (i) all nonresidential uses; (ii) all mixed uses; (iii) all residential uses, except for single-family residential uses; provided, however, if the Town becomes aware of a cross-connection at a specific single family residential use, then this Chapter shall apply to such single family residential use; and (iv) bulk water sold by the Town. This Chapter also applies to all out of Town water users as provided in Section of this Chapter. Page 1

APPROVED BACKFLOW PREVENTION DEVICE (ASSEMBLY): A device listed in the latest University Of Southern California, Foundation For Cross Connection Control And Hydraulic Research "list of approved backflow prevention assemblies". AUXILIARY WATER SUPPLY: Any water supply on or available to the premises other than the town's water system. These auxiliary water supplies may include, but are not limited to, water from another water supplier's potable water supply or any natural source(s) such as well, spring, river, stream, pond, or lake, "used waters" or "industrial fluids". These waters may be polluted or contaminated, or may be objectionable and constitute an unacceptable water source over which the town does not have sanitary control. BACK PRESSURE: Backflow caused by a pump, elevated tank, boiler, or "head" in pipe, or any means that could create greater pressure within a piping system than that which exists within a potable water supply system. BACK SIPHONAGE: The reverse flow of water or other liquids, mixtures, gases or substances into the distribution pipes of a potable water supply system caused by negative or subatmospheric pressure in the potable water supply system. BACKFLOW: The undesirable reversal of the direction of flow of the water or mixtures of water and other liquid, gases, or other substances into the distribution pipes of a potable water supply system from any source or sources caused by back pressure and/or back siphonage.

HAZARD, POLLUTION: An actual or potential threat to the physical properties of the water system or to the potability of the water system or the water user's potable water system which would constitute a nuisance or be aesthetically objectionable or could cause damage to either of such systems or its appurtenances, but would not be a threat to life or be dangerous to health. HAZARD, SYSTEM: An actual or potential threat of severe damage to the physical properties of the water system or the water user's potable water system, or of a pollution or contamination which would have a protracted effect on the quality of the potable water in either of such systems caused by a cross connection. INDUSTRIAL FLUIDS SYSTEM: Any system containing a fluid or solution which may be chemically, biologically, radiologically, or otherwise contaminated or polluted in a form or concentration such as would constitute a health, system, pollution or plumbing hazard if introduced into an approved water supply.

NONPOTABLE WATER: Water that is not safe for human consumption or that does not meet the requirements set forth in the state of Colorado primary drinking water regulations. POLLUTION: The presence of any foreign substance (organic, inorganic, radiological or biological) in the water that may degrade the water quality so as to constitute a nonhealth type hazard or impair its usefulness. POTABLE WATER: Water free from impurities in amounts sufficient to cause disease or harmful physiological effects. The bacteriological, chemical, and radiological quality shall conform with the state of Colorado primary drinking water regulations. POTABLE WATER SUPPLY: The town's water system, or a water user's potable water system. REDUCED PRESSURE PRINCIPLE DEVICE: An assembly of two (2) independently operating approved check valves with a hydraulic automatic operating differential relief valve between the two (2) check valves. The assembly shall be located between two (2) check valves. The assembly shall be located between two (2) tightly closing (resilient seated) shutoff valves, and have four (4) properly located test cocks for the testing of the check and relief valves. The entire assembly shall be an approved backflow prevention device. SUBMERGED INLET: A water pipe or extension thereof from a potable water supply terminating below the flood level rim of a tank, vessel, fixture or appliance which may contain water of questionable quality, waste or other contaminant or pollutant. VACUUM: Any pressure less than atmospheric pressure. VACUUM BREAKER, ATMOSPHERIC NONPRESSURE TYPE: A vacuum breaker consisting of an air inlet opening and a nonloaded floating check disk valve designed to prevent back siphonage only. The device shall not be subjected to continuous static line pressure or back pressure or be installed where it would be under pressure for more than twelve (12) continuous hours. VACUUM BREAKER, PRESSURE TYPE: A vacuum breaker, designed to prevent back siphonage only, consisting of a spring loaded check valve, a spring loaded air inlet opening, a tightly closing shutoff valve on each side of the device, and two (2) appropriately located test cocks. The device shall not be subjected to back pressure. The entire assembly shall be an approved backflow prevention device. WATER DISTRIBUTION AND WASTEWATER COLLECTION SYSTEMS CERTIFICATION COUNCIL: The group designated by the Colorado department of health to administer and maintain the cross connection control technician certification program. WATER SERVICE CONNECTION: The terminal end of the service connection from the town's potable water distribution system; i.e., where the town loses jurisdiction and sanitary control over the water at its point of delivery to the water user's stop and waste valve or meter, whichever comes first from the water main. If a meter is installed at the end of the service connection, then the service connection shall mean the downstream end of the meter. There shall be no unprotected takeoffs from the service line ahead of any meter or backflow prevention device located at the point of delivery to the water user's potable water system. This shall include irrigation systems and fire sprinkler systems. Service connection shall also include water service connection from a fire hydrant and all other temporary or emergency water service connections from the potable water system.
