screwed to the well casing with a minimuia of 5 foot 6 inch bury from
finished grade to the center of the discharge opening. The inside
diameter of the well casing, unless the seal is recessed into the dis-
charge 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 pit -
less unit to the pressure tank shall be Type K copper pipe or schedule
40 P. V. C. (plastic), and shall have equivalent diameter to the pump
drop pipe. The submersible cable from the pitless unit into the basement

(i) No well shall hereafter be installed in a pit below the sur-
face 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 seal 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
basement floor and sloped to the drain away from the well casing.
(j) No pump shall hereafter be installed that uses the well

L�
shall employ a consulting engineer to assist the Village Engineering
Department in the approval of plans and in the supervision of the systems
during construction. The full fee paid to such consulting engineer shall

the minimum well size shall be 4", whieb well shall test pump for 3 hours
at not less than 1200 gallons per hour with no appreciable drop in the
static level. The owner and inspector shall have the right to observe
this test, measure the well or have said well checked to his satisfaction.
All such wells shall be fitted with a permanent pump which shall produce

permanent pump produce less than 500 gallons per hour at a pressure of
40 pounds per square inch.
17.08 Log required. A log of the well shall be made showint the
nominal size as ep of the casing from outside ground elevatio;L. This
log shall also state the results of a flow test made at the completion
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 specified rate 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 near the electric
service box.
17.09 Cleaning Before Use. Drinking water supply systems must be
disinfected Tollowing cons ruction or alteration. One pound of calcium

and allowed to remain in the well and supply system for at least 12 hours,
following which the water shall be pumped to waste until the odor and
tast of the chemical has disappeared.
17.10 Abandoned Wells. Until a well is permanently abandoned, all
provisions for pro ec ion 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 possible. Neat cement grout, concrete or puddled cla; 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.
17.11 Wells for Disposing of Wastes. The construction of a well for
the purpose of disposing of any iqui , including surface water, air
conditioning, or commercial wastes, shall be prohibited unless authorized and
approved by the State of Minnesota Water Polution Control Commission.

well, an may inspect the work in progress, the materials, testing,
measurements, etc. at their discretion. Any licensee in violation of this
section 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.
17.13 Objectives. The objectives of this section are to provide
adequate anUls-a-75-73M6stic water supply. Any system of special, unusual
or new design which will satisfy the stated objectives may be accepted as
complying with this section, and any permit granted for the construction,
installation, alteration, or repair of any such apecial system shall be
subject to such conditions and guarantees as may be stated in the permit.
