The purpose of this subchapter is:
(A) To protect the city's municipal water system from contaminants or pollutants by isolating sources of contaminants or pollutants within a customer's internal water distribution system which could backflow or back siphon into the city's water system;
(B) To eliminate and control cross-connections that exist between a customer's potable water system and non-potable water systems; and
(C) To evaluate and reduce the following potential hazards to the city's potable water supply such as:
(1) HEALTH HAZARD. Any actual or potential threat of contamination of a physical or toxic nature to the city's water system or the consumer's potable water system that would create or, in the judgement of the Director, may create a danger to health.
(2) PLUMBING HAZARD. Any internal or plumbing type of cross-connection in a customer's potable water system that may be either a pollutant or contamination-type hazard. The term PLUMBING HAZARD includes, but is not limited to, cross-connections to toilets, sinks, lavatories, wash trays, recycled/reclaimed water systems, washing machines or lawn sprinkling systems. Plumbing type cross-connections may be located in many types of structures, including homes, apartment houses, hotels and commercial and industrial establishments. An appropriate type of cross-connection control assembly, if permitted, must properly protect such a connection.
(3) POLLUTION HAZARD. Any actual or potential threat to the physical properties of the water system or to the potability of the city's or the consumer's potable water system, but which would not constitute a health or system hazard, as defined.
(4) SYSTEM HAZARD. Any actual or potential threat of severe damage to the physical properties of the city's water system or the consumer's potable water system or of a pollutant or contaminant that may have a protractive effect on the quality of the potable water in the system.
(5) INDUSTRIAL FLUIDS SYSTEM HAZARD. Any fluid or solution that may be chemically, biologically or otherwise contaminated or polluted in a form or concentration such as to constitute a health, water system, pollution or plumbing hazard if introduced into an approved water supply. This type of contamination includes but is not limited to polluted waters; all types of process waters and used waters; chemicals in fluid form; plating acids and alkalies; circulated cooling tower waters (open or closed) that may be chemically or biologically treated or stabilized with toxic substances; contaminated natural waters, such as from wells, springs, streams, rivers, harbors or irrigation canals; oils; gases; glycerine; caustic and acidic solutions; and all other solutions which may be used for industrial or firefighting purposes.
