Nf
Section 9. Test Pumping Requirements, Each private water supply system
must produce a minimum of 1 ,?00 gal Ions per hour for a period of at least 3 hours

qv
)450 ga I Ions per hour ,at 20 1 bs. pressure.
Section 10. Casings. At drilled wells, constructed in geological for-
mations of sand,gravel , or other formations of a caving nature, extending the full

pumping level . All well casing shall be new, prime black pipe, reamed and drifted,
bearing the mill label (manufacturer' s name). If the pipe is threaded and coupled,
the couplings must be of heavy drive type which, when properly made up, will com-
pletely bury the pipe threads. If the pipe is to be welded in place, it must be

Section II . Grouting Casing . An oversize drill hole shall extend to a
depth of at least 20 feet to permit placement of a cement grout seal around the

than the permanent casing shall be used for the oversize drillhole if the well is
drilled by the cable-tool method. T ernporary casing sliall be oul ► ed as grout ; s ntacpH.
An open hole at least 3-inches in diameter larger than the outside diameter
of the casing pipe shall be provided if temporary casing in the oversize hole is
not needed, as in drilling by the rotary method. Then the permanent casing is
fixed in its final position, the space around it in the oversize drillhole shall
be grouted by adding cement slurry from the bottom of the area to be grouted upward
in one continuous operation. Grouting shall be carried to the ground surface or to

6 inch bury from finished grade to the center of the discharge opening. The inside
diameter of the pitless stand pipe shall be larger than the inside diameter of the
well casing, unless the seal is recessed into the discharge so as to cause no
restriction in the casing. The stand pipe must be 8 inches above the finished
grade. The discharge piping from the pitless un7t to the pressure tank shall be
Type "KT' copper pipe and sha I I have diameter equivalent to t.• a -;,, :p rop pipe, All

uses the we 1 I casing for a vacuum-line or �e� I i ne purpose, nor shall any
pump be installed having a buried horizontal suction pipe between the building and
any below-surface Pitless well , except where the suction pipe is encased in preseurp
pipe. Pitless well and pumping systems may be installed using a buried horizontal
pressure line between well and building if there is maintained a min.i,mum pressure
of twenty (20) pounds per square inch.

Section 14. Installation of Submersible Pump. When a submersible pump
is used, it must be set with sufficient drop pipe so that the top of the pump is
set below the pumping level in the well when pumped at a rate of fifty (50) percent
greater than the capacity of the permanent pump.
Section 15. Pump Discharge, WeII Pit. If the well is constructed within
a well pit attached to the basement of the buildinq, the top of the well shall be
equipped with a sanitary well seal .
Section 16. Hydro-pneumatic Pressure Tank. ;

(b) Accessories. The following valves and fittings shall be installed tn
complete this system:
1 . Square head valves on i nk et and discharge of pressure tank as close
to tank as practical .
2. Hose bib-cock at lowest opening on pressure tank.
3. Ground ,joint union or dresser coupling in discharge line from well
to tank on well side of union or dresser coupling.
' 4. Air re-charge system,or air-saver tvpF tank .
Section 17. Cleaning Before Use. Drinking water supply systems must be
disinfected following construction or repair. One pound of calcium hypochlorite mixed

etc. at their discretion. Any licensee in violation of the above ordinance shall
be subject to fine or imprisonment, as well as correction of work or materials that
do not conform to this ordinance. The well contractor can proceed with his work
if the Lnspector does not visit the site to check on test pumping within 3 hours
after the well contractor notifies the Village Inspection Department of testing
operations.
Section 19. Engineering Standards. Workmanship shall meet approved
engineering standards. Any spiit or break in the well casinq will be prima facie
evidence of failure to meet such approved engineering standards.
