This article shall be known and may be cited as the "Water Well Regulations"
to the Code of the Township of Antrim.
The intention of this article is to ensure and protect the quality and
suitability of domestic water supply and to secure and maintain the minimum
required isolation distances between water supplies and sewage disposal systems
or other sources of contamination.
The following standards shall apply:
A. Location. Drilled and driven wells shall be located at
a point free from flooding at the following minimum distances to existing
or possible future sources of pollution:

B. Source of water. The source of supply shall be from a
water-bearing formation drawn not less than 100 feet from the ground surface,
with at least 20 feet of properly grouted well casing, and from no formation
which is subject to pollution.
C. Construction.
(1) The well shall have a watertight and durable wrought
iron, steel or other type of approved casing with a nominal thickness of 3/16
(0.1875) inches and 6 5/8 inches outside diameter. The sections shall
be joined together by threaded couplings, joints, by welding or any other
watertight approved joint or coupling.
(2) Twenty feet from the finishing grade and in any case
shall be extended 10 feet into bedrock or other impervious strata. Driven
wells shall be provided with a drive shoe or other effective casing seal.
(3) The casing shall be sealed effectively against entrance
of water from water-bearing formations, which are subject to pollution, through
which the casing may pass. If casings of smaller diameter are used in the
lower portions of the well, effective watertight seals shall be provided between
the casings where they telescope. In such instances, sections of casing shall
telescope for a minimum distance of four feet.
(4) The top of the well casing shall extend a minimum of
eight to 12 inches above the finished grade of the lot so that contaminated
water or other substances cannot enter the well through the annular opening
at the top of the well casing, wall or pipe sleeve.
(5) Every potable water well shall be equipped with an overlapping
cover of the top of the well casing or pipe sleeve. Covers shall extend downward
at least two inches over the outside of the well casing or wall. All well
caps shall indicate well driller's main, depth of well and depth of casing.
(6) Where pump sections or discharged pipes enter or leave
a well through the side of the casing, the circle of contact shall be watertight.
The use of plastic/nylon adapters for this purpose is not acceptable. A brass
pitless adapter with brass connectors or equivalent are required.
(7) All potable water wells and springs shall be constructed
so that surface drainage will be diverted away from the well or spring.
(8) Any pump room or any enclosure around the well pump shall
be drained and protected from freezing by heating or other approved means.
Where pumps are installed in basements, they shall be mounted on a block or
shall not be less than 18 inches above the basement floor. Well pits shall
be prohibited.
D. Water service. Size of water service pipe. The minimum
diameter of water service pipe shall be 3/4 inch separation of water service
and building sewer/drain water service pipe shall be installed 12 inches above
sewer drains.
The provisions of this article shall be severable, and if any of its
provisions shall be held to be unconstitutional, illegal or invalid, such
unconstitutionality, illegality or invalidity shall not affect the validity
of any of the remaining provisions of this article.
No responsibility or liability for the construction of any well/water
supply shall be deemed to be assumed or accepted by the Township of Antrim
or its officers, agents or employees by virtue of the terms of this article
or otherwise.
