As used in this article, the following terms
shall have the meanings indicated:
BACKFLOW
Water of questionable quality, wastes, or other contaminants
entering a public water supply system due to a reversal of flow.
CROSS-CONNECTION
A connection or arrangement of piping or appurtenances through
which water of questionable quality, wastes or other contaminants
can enter the public water supply system.
SAFE AIR GAP
The minimum distance of a water inlet or opening above the
maximum high water level or overflow rim in a fixture, device, or

not be less than one inch and need not be more than 12 inches.
SECONDARY WATER SUPPLY
A water supply system maintained in addition to a public
water supply, including, but not limited to, water systems from ground
or surface sources not meeting the requirements of Act No. 399 of
the Public Acts of 1976, being §§ 325.1001 to 325.1023
of the Michigan Compiled Laws, or water from a public water supply
which in any way has been treated, processed, or exposed to any possible
contaminant or stored in other than an approved storage facility.
SUBMERGED INLET
A water pipe or extension thereto from a public water supply
terminating in a tank, vessel, fixture, or appliance which may contain
water of questionable quality, waste or other contaminant, and which
is unprotected against backflow.
WATER UTILITY
A governmental unit, municipal or private corporation, association,
partnership, or individual engaged in furnishing water to the public
for household or drinking purposes. This definition includes the Township
of Grosse Ile.
It shall be the duty of the Grosse Ile Department
of Public Works (GIDPW) to cause inspections to be made of all properties
served by the public water supply where cross-connection with the
public water supply is deemed possible. The frequency of inspections
and reinspections based on the potential health hazards involved shall
be as established by the GIDPW and as approved by the MDEQ, or it
successor agency, if required.
The representative of the GIDPW shall have the
right to enter at any reasonable time any property served by a connection
to the public water supply system of the Township of Grosse Ile for
the purpose of inspecting the piping system or systems thereof for
cross-connections. On request, the owner, lessees, or occupants of
any property so served shall furnish to the inspection agency any
pertinent information regarding the piping system or systems on such
property. The refusal of such information or refusal of access, when
requested, shall be deemed evidence of the presence of a cross-connection.
The GIDPW is hereby authorized and directed
to discontinue water service after reasonable notice to any property
wherein any connection in violation of this article exists and to
take such other precautionary measures deemed necessary to eliminate
any danger of contamination of the public water supply system. Water
service to such property shall not be restored until the cross-connection(s)
have been eliminated in compliance with the provisions of this article.
All testable backflow prevention devices shall
be tested initially upon installation to be sure that the device is
working properly. Subsequent testing of devices shall be conducted
at a time interval specified by the GIDPW and in accordance with MDEO
requirements. Only individuals approved by the GIDPW shall be qualified
to perform such testing. That individual(s) shall certify the results
of his/her testing.
The potable water supply made available on the
properties served by the public water supply shall be protected from
possible contamination as specified by this article and by the state
and the Township of Grosse Ile Plumbing Code. Any water outlet which could be used for potable or domestic
purposes and which is not supplied by the potable system must be labeled
in a conspicuous manner as "WATER UNSAFE FOR DRINKING".
This article does not supersede the State Plumbing
Code and the Township of Grosse Ile Plumbing Ordinance, but is supplementary
to them.
Any person or customer found guilty of violating
any of the provisions of this article or any written order of the
GIDPW, in pursuance thereof, shall be deemed guilty of a misdemeanor
and, upon conviction thereof, shall be punished by a fine of not more
than $500 for each violation and/or 90 days in jail. Each day upon
which a violation of this article shall occur shall be deemed a separate
and additional violation for the purpose of this article.
