					 of the drinking water provided by the public water system. This definition
					 includes any arrangement of piping where a potable water line is connected to
					 non potable water; it may be a pipe-to-pipe connection where potable and non
					 potable water lines are directly connected or a pipe-to-water connection where
					 the potable water outlet is submerged in non-potable water. If the potable and
					 non-potable source are separated by gate valves, check valves or devices other
					 than the appropriate backflow preventer as outlined by this regulation, a cross
					 connection exists. By-pass arrangements, jumper connections, swivel or change
					 over assemblies, or other temporary or permanent assemblies through which, or
					 because of which, backflow may occur are considered to be cross connections.

Public water
					 system
means a system for the provision to the public of water for Human
					 consumption through pipes or, after August 5, 1998, other constructed
					 conveyances, if such system has at least fifteen service connections or
					 regularly serves an average of at least twenty-five individuals daily at least
					 60 days out of the year. Furthermore, two or more water systems that are
					 adjacent, that are owned or operated by the same supplier of water, that
					 individually serve less than 15 service connections or less than 25 persons but
					 in combination serve 15 or more service connections or 25 or more persons,
					 shall also be defined as a public water system. Such term includes: Any
					 collection, treatment, storage, and distribution facilities under control of
					 the operator of such system and used primarily in connection with such system;
					 and any collection or pretreatment storage facilities not under such control
					 which are used primarily in connection with such system. Such term does not
					 include any "special irrigation district." Service connection, as used in the
					 definition of public water system, does not include a connection to a system
					 that delivers water by a constructed conveyance other than a pipe if:
a. The water is used exclusively for purposes
					 other than residential uses (consisting of drinking, bathing, cooking, or other
					 similar uses);
b. The Director or
					 Administrator determines that alternative water to achieve the equivalent level
					 of public health protection provided by the applicable national primary
					 drinking water regulation is provided for residential or similar uses for
					 drinking and cooking; or
c. The
					 Director or Administrator determines that the water provided for residential or
					 similar uses for drinking, cooking, and bathing is centrally treated or treated
					 at the point of entry by the provider, a pass-through entity, or the user to
					 achieve the equivalent level of protection provided by the applicable national
					 primary drinking water regulation.
d. Special irrigation district means an
					 irrigation district in existence prior to May 18, 1994, that provides primarily
					 agricultural service through a piped water system with only incidental
					 residential or similar use where the system or the residential or similar users
					 of the system comply with the exclusion provisions in Section 1401(4)(B)(i)(II)
					 or (III) of the Federal Safe Drinking Water Act.
