structed without a well pit, the contractor shall furnish and install

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 3 inches above the
finished grade. The discharge piping from the pitless unit to the

and shall have equivalent diameter to the pump drop pipe. The sub-
mersible cable from the pitless unit into the basement or building
shall be run in rigid conduit or an approved Underwriters Laboratory
trench lay wire. The conduit or trench lay wire shall be buried a
minimum of 2 feet below the surface of the ground. All fittings used
in connection with the copper discharge piping underground shall be of
a flare type. The top of the pitless unit shall be equipped with a
well vent.
Section 5. Subd. 9. Pump Discharge, Well Pit. No well shall hereafter
be installed in a pit below the surface of the ground unless such well
pit is in an alcove opening directly into the main basement area of the
building being served by the well.

sanitary well seLl that is extended at least 12 inches above the lowest
part of the basement floor and 6 inches above the floor directly adjacent
to the well.
(B) The well pit floor shall be at least 6 inches above the base-
ment floor and sloped to the drain away from the well casing.
(C) Pump restrictions, no pump shall hereafter be installed that
uses the well casing for a vacuum line or pressure line purpose, nor
shell 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 pressure pipe.

Section 6. Community later Systems. Comruunity water systems or wells
supplying 3 or more residences shall be permitted only after plans
have been submitted to, and approved by, the Village Council or its
agent. For all community water systems the Village shall employ a
consulting engineer to assist the Village 'Ingineering Department in
the approval of plans and in the supervision of the systems during
construction. The full fee paid to such consulting engineer shall be
borne by the owner.
Section 7. ?est Pumping Requirements. teach private water supply systern
must produce a minimum of 1200 gallons of water per hour for a period of
at least 3 hours of test pumping without ac appreciable drop in the
somatic level. The owner and inspector shall have the right to observe
this test, measure the well or have said well checked to his satisfaction.
111 such wells shall be fitted with a permanent pump which shall produce
not less than 50� of the test pumping rate :nor more than 7%9' of such
test pumping rate, but in no case shall the permanent pump produce lose
than 600 gallons per hour at a pressure of 40 lbs.
Section 8. Log Required. A log of the well shall be made showing the
nominal size and depth of the casing from outside ground elevation.
This log shall also state the results of a flow test made at the com-
pletion of the well, the static level of the water in the well, and
the drop in feet from the static level after pumping at the rate of
1200 gallons per hour for 3 hours. One copy of the log shall be filed
with the Village Building Inspection Department and one copy posted
in the building now the electric service box.
Section 9. Cleaning Before Use. Drinking water supply systems must
be disinfected following coneVuction or alteration. One pound of
calcium hypochlorite mixed with 5 gallons of water shall be poured
into the well and allowed to remain in the well and supply system for
at least 12 hour@, following which the water shall be pumped to waste
until the odor and taste of the chemical has disappeared.
Section 10. Abandoned Wells. Until a well is permanently abandoned,
all provisions for protection of the water against contamination and
pollution and for maintaining satisfactory sanitary conditions around
the well shall be carried out to the same extent as though the well
were in routine use. When a well is permanently abandoned a well
permit must be obtained. The well shall be disconnected from the
system and the hole filled to prevent contaminating materials from
entering the water bearing ground formations through it. The inspector
shall witness the filling of the well. Concrete or cement grout are
the most satisfactory filling materials. If the well is so large that
the use of these materials is not practical, the filling material
selected shall be such as to restore natural conditions as far as possi-
ble. Neat cement grout, concrete or puddled clay are satisfactory
for filling parts of wells in rock formations and natural earth or
puddled clay may be used in drift sand and gravel sections of wells.
In any case, the top ten feet of any permanently abandoned drilled
well shall be filled with concrete.
Section 11. dells for Disposing of Wastes. The construction of a
well for the purpose of disposing of any liquids, including surface
waters, air conditioning, or comwercial wastes, shall be prohibited
unless authorised and approved by the State of Minnesota Polution
Control Board.
Section 12. Inspection. The Village Building Inspection Department
must be notified before the well is test pumped, as in Section 7 or
abandoned as in Section 10. The Department reserves the right to
require inspection of every well, or to spot check in lieu of checking
every well, and may inspect the work in progress, the materials,
testing, measurements, etc. at their discretion. Any licensee in
violation of this 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 Inspector
does not visit the site to check on test pumping within 4 hours after
the well contractor notifies the Village Inspection Department of
testing operations.
If upon inspection the inspector discovers that any part of the system
is not constructed in accordance with the minimum standards provided
in this ordinance, he shall give the applicant written notification
describing the defects. The applicant shall pay an additional fee of
`5.00 for each reinspection that is necessary. The applicant shall be
responsible for the correction or elimination of all defects, and no
system shall be placed or replaced in service until all defects have
been corrected or eliminated.
Sec. 13. Objectives. The objectives of this ordinance are to provide
adequate a.xl safe domestic water supply. Any system of special, unusual
or new design which will satisfy the stated objectives may be accepted
as complying with this ordinance, and any permit granted for the
construction, installation, alteration, or repair of any such special
system shall be subject to such conditions and guarantees as may be
stated in the permit. This ordinance does not apply to irrigation or
industrial purposes. Shopping Center wells and larger systems will
require the State Board of Health approval. Consideration should be
given to locating shopping center wells away from buildings with
separate power source, so that they may be used to fight fires. This
ordinance applies to wells for domestic "ad residential use.
Sec. 14. Penalties. Any person, firm or corporation violating any of
the provisions of this ordinance shall be guilty of a misdemeanor, and
upon conviction thereof shall be fined in an amount not to exceed 0100.00
