For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
AIR-GAP. An unobstructed vertical distance through atmosphere between the discharge end of a pipeline supplied from a public water supply, and the overflow rim of the receiving portion of the customer water system.
COMMISSIONER. The executive and the chief administrative officer of the Indiana Department of Environmental Management.
CROSS-CONNECTION. Any physical arrangement, including cross-connection control devices not in working order, whereby a public water supply distribution system is directly connected, either continuously or intermittently, with any secondary source of supply, sewer, drain, conduit, pool, piping, storage reservoir, plumbing fixture or other device which is capable of imparting to the public water supply, contaminants, contaminated water, sewage or other waste or liquid of unknown or unsafe quality.
CROSS-CONNECTION CONTROL INSPECTOR. A person who has successfully completed training in testing and inspection of cross-connection control devices at any agency or school acceptable to the Commissioner of the Department of Environmental Management.
DOUBLE CHECK VALVE ASSEMBLY. A device or assembly composed of two tightly closing shut-off valves surrounding two independently acting check valves, with four test cocks, one upstream of the four valves and one between each of the four check and shut-off valves.
DOWNSTREAM. The normal direction of water flow from the public supply to the user. Upstream is that direction which is opposite of downstream.
HAZARD. The danger of public water contamination caused by chemical, bacteriological or other sources that may, under certain conditions such as backflow, enter the public water supply system.
POTABLE WATER. Water that is suitable for drinking as determined by the requirements of the Federal Safe Drinking Water Act, being 42 U.S.C. §§ 300f et seq.
PRESSURE VACUUM BREAKER. An assembly containing an independently operating internally loaded check valve and an independently operating loaded air inlet valve located on the discharge side of the check valve. The assembly is to be equipped with properly located test cocks and tightly closing shut off valves attached to each end of the assembly.
PRIVATE WATER SUPPLY SYSTEM. Consists of private wells or other private water supplies which are normally entirely independent and not connected to the public water supply.
PRIVATE WATER SUPPLY SYSTEM. Consists of the lateral fire and service line to the user's premises starting at the tap on the public water supply system and terminating at the point-of-usage; whether for fire-suppression, irrigation or domestic usage.
PUBLIC WATER SUPPLY SYSTEM. Consists of the water mains and appurtenances such as fire hydrants and main valves used to distribute the potable water supply to the public, and shall terminate at the tap for lateral service to the users; the utility is the owner of the public water supply system.
REDUCED PRESSURE BACKFLOW PREVENTER. A device which is composed of two tightly closing shut-off valves surrounding two independently acting press reducing check relief valves, and four test cocks, one upstream of the five valves and one between each of four check and shut-off valves. The check valves effectively divide the structure into three chambers; pressure is reduced in each downstream chamber allowing the pressure differential relief valve to vent the center chamber to atmosphere should either or both check valves malfunction.
USER. The water customer or public authority using potable municipal water.
UTILITY. The City of Ligonier Water Works, a municipally owned utility.
