[Ord. No. 97-13, Sec. 1]
In compliance with Arkansas Rules and Regulations Pertaining
to Public Water Systems, Section VII.E, the Lincoln City Council finds
it necessary for the health, safety and welfare of the people served
by the water department of the City's utility department to adopt
cross-connection control standards which establish the requirements
for the design, construction and maintenance of connections to the
public water supply. These standards are supplemental, but do not
supersede or modify the State Plumbing Code and its latest revisions
under which the City operates. This ordinance pertains to commercial
and industrial establishments only. Single-family, residential swelling
units, unless involved in commercial operations, are exempt from the
requirements of this ordinance except where they fall under the purview
of the Arkansas State Plumbing Code.
A. The purpose of this ordinance is:
1. To provide for the protection of the public potable water supply:
2. To isolate at the service connection any actual or potential pollution
or contamination within the consumers' premises; and
3. To provide a continuous, systematic and affective program of cross-connection
control.
