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.[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.

Editor's Note: Table 1 is included at the end of this chapter.
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.
A.
Bored-type wells. Construction of this type well shall
be subject to regulations specified by the Whitpain Township Board
of Supervisors at the time of application.
B.
Driven-point wells. Construction of this type well
shall be subject to regulations specified by the Whitpain Township
Board at the time application is made.
C.
Dug-type wells. Construction of this type well shall
be subject to regulations specified by the Whitpain Township Board
at the time of application.
D.
Conversion of dug-type wells. Construction of this
type well shall be subject to regulations specified by the Whitpain
Township Board at the time of application and in this subsection:
(1)
Preparation for deepening. Any sediment or debris
in the bottom of the dug well shall be removed. The bottom shall be
disinfected by distributing a chlorine solution over the bottom or
adding such solution to water in the well. A concentration of 200
parts per million of chlorine should be attained for disinfection.
(2)
Applicability to drilled-type construction. Deepening construction done by drilling methods shall conform to applicable conditions of § A167-9. Existing dug- and drilled-type wells shall be effectively protected against entrance of surface and near-surface water by extending the casing pipe of the drilled part of the well to the surface and filling the dug part of the well with puddled clay or equally impermeable material.
