The requirements of §
A167-6 shall be deemed to be fulfilled to the minimum extent when a drilled well has been installed in conformity with the applicable construction set forth in Table 1.
A. Well-casing pipe. The minimum standard of quality
for casing shall be new steel or wrought iron equivalent to full-weight
standard pipe in sizes eight inches and over, and pipe for sizes under
eight inches, full-weight standard.
B. All connections to a well casing and all joints in
the casing itself must be assembled pressure-tight, made up of correctly
mated threaded pipe fittings, welded connections, sanitary well seals
or other approved connections.
C. Well-casing pipe shall be driven or installed so that
no injury affecting the safety of the water supply results.
D. Upon completion of drilling, the well shall be equipped
with a suitable watertight cap or plug to protect the well from tampering
or from the entrance of foreign matter.
E. (Also see §
A167-12.) Provision for sounding water levels and water level indicating device.
(1) A well used for domestic purposes shall be equipped
with an access opening extending at least to ground level to permit
sounding of water level in the well. This opening shall be three-eighths-inch
or larger pipe, properly sealed with a watertight cap or plug to prevent
access of surface water. This access pipe may be a part of the well
venting system.
(2) A well used for commercial or industrial purposes
shall, in addition to the above, be equipped with an approved water
level indicating device.
The construction of flowing wells shall comply with the minimum requirements of §
A167-9.
A. Every practicable effort shall be made to extend the
watertight (cased and cement-grouted) construction into the upper
confining bed of the artesian basin.
B. When it is impractical to extend the watertight construction indicated in Subsection
A, an adequate packer shall be set and maintained in the confining bed with a flow pipe extending therefrom to a point at least one foot above the established grade.
