within three (3) years of the date of the adoption of this Ordinance.
Where there is evidence of septic tank effluent percolating from
the ground, the system must be corrected and conform to these
standards within ninety (90) days after written notification.
Subd. A. General Requirements. The following requirements
must be satisfied:
(1) Location and installation of the individual
sewage disposal system and each part thereof
shall be such that, with reasonable main-
tenance, it will function in a sanitary
manner and will not create a nuisance nor
endanger the safety of any domestic water
-2-
supply. In determining a suitable location
for the system, consideration shall be
given to the size and shape of the lot,
slope of natural and finished grade,
soil permeability, depth of ground water,
geology, proximity to existing or future water
supplies, accessibility for maintenance, and
possible expansion of the system.
(2) No part of the system shall be located so
that it is nearer to any water supply than
outlined hereinafter, or so that surface
drainage from its location may reach any
domestic water supply.
(3) Raw sewage, septic tank effluent, or seepage
from a soil absorption system shall not be
discharged to the ground surface, abandoned
wells, or bodies of surface water, or into
any rock formation the structure of which is
not conducive to purfication of water by
filtration, or into any well or other
excavation in the ground which does not
comply with the requirements of this Ordinance.
This requirement shall not apply to the
disposal of sewage in accordance with a
process approved by the State Board of Health
or the Water Pollution Control Commission.
(4) The lot size shall be sufficient to permit in-
stallation of the individual sewage disposal
system in accordance with all the requirements
pertaining thereto.
(5) Installations of individual sewage disposal
systems shall not be made in low swampy
areas or areas which may be subject to
flooding.

the installation of a system adequate for
such anticipated need shall be required.
(9) The system shall consist of a building sewer,
a septic tank, and a soil absorption unit.
The soil absorption unit shall consist of a
sub-surface disposal field. All sewage
shall be treated in the septic tank and
the septic tank effluent shall be discharged
to the disposal field. The septic tank
drain field system shall be considered the
only acceptable system for installation
unless it can be demonstrated that this
system is not feasible on the particular
lot in question and if it can be demonstrated
that this system is not feasible on the
particular lot in question and if it can
be demonstrated that the system being proposed
as an alternate will not create a pollution
problem.

within the area utilized for the absorp-
tion field, serial distribution may be
used. The bottom of the trenches and
distribution lines shall be constructed
a relatively level grade. The distrib-
ution tile system shall be arranged
so that each trench shall be filled
with septic tank effluent before
effluent flows to succeeding trenches.
The invert of the overflow pipe in
the first relief line shall be at
least four (4) inches lower than the

as applied to Table 2.
(a) Number and location of tests . Two or
more tests shall be made in separate
test holes spaced uniformly over the
proposed absorption field site .
(b) Type of test hole. A hole with horizon-
tal dimensions of four (4) to twelve
(12) inches and vertical sides shall
be dug or bored to the depth of the
proposed absorption trench. The holes
may be bored with an auger of not less
than four (4) inches in diameter.
-10-
(c) Preparation of test hole. The bottom
and sides of the hole shall be care-
fully scratched with a knife blade or
sharp pointed instrument to remove
any smeared soil surfaces and to
provide a natural soil interface into
which water may percolate. All loose
material shall be removed from the
hole and two (2) inches of coarse sand
or fine gravel shall be added to protect
the bottom from scouring.
(d) Saturation and swelling of the soil.
The hole shall be carefully filled with
clear water to a minimum depth of
twelve (12) inches over the gravel.
Water shall be kept in the hole for
at least four (4) hours , and preferably
overnight, by refilling if necessary,
or by supplying a surplus reservoir
of water, such as in an automatic
siphon. In sandy soils containing
little or no clay, the swelling pro-
cedure shall not be required and the
test may be made as described under
Subd. D. (4) (e) (3) after the water
from one filling of the hole has
completely seeped away.
(e) Percolation rate measurement. With the
exception of sandy soils, percolation
rate measurements shall be made on the
day following the procedure described
under Subd. D. (4) (d) .
(1) If water remains in the test hole
after the overnight swelling period,
the depth shall be adjusted to
approximately six (6) inches over the
gravel. From a fixed reference point
the drop in water level shall be
measured at thirty (30) minute intervals
over a two (2) hour period. This drop
shall be used to calculate the percol-
ation rate.
-11-
(2) If no water remains in the hole
after the overnight swelling period,
clear water shall be added to bring
the depth of water in the hole to
approximately six (6) inches over
the gravel. From a fixed reference
point the drop in water Level shall be
measured at approximately thirty (30)
minute intervals for four (4) hours,
refilling six (6) inches over the
gravel if necessary. The drop that
occurs during the final thirty (30)
minute period shall be used to calculate
the percolation rate.
(3) In sandy soils or other soils
in which the first six (6) inches of
water seeps away in less than thirty
(30) minutes after the overnight swell-
ing period, the time interval between
measurements shall be taken as ten (10)
minutes and the test shall be run for
one (1) hour. The drop that occurs
during the final ten (10) minutes
shall be used to calculate the
percolation rate.
