SITE EVALUATOR:_Koch ' s Soil Testing REPORT DATE: February 13 , 1997
The City of Orono has Approved your on-site system design as ofFebruar y 18 , 1997
(approved-disapproved) (date)
with the following continents: A third drainfield site is shown on the report,
however, it is not an approved site until soil borings and percolation
tests can be completed. The approved sites are those located on the
south end of the property, west of the proposed residence .
THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A permit must
be issued to a licensed septic contractor prior to installation. A list of currently licensed septic contractors is
enclosed.
NOTICE TO INSTALLERS: Any changes to the approved plans and specs must have prior approval of the
Inspector (473-7357). Call for inspections 24 hours in advance.
ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain
in place until final site grading. Approval to pour footings will not be granted until the Inspections Department
has verified that primary and alternate sites are adequately protected.
NO VEHICULAR TRAFFIC OF ANY KIND (cars, trucks, earth moving equipment, etc.) is allowed within 20'
of tested drainfield sites either before or after system construction. Compaction of these areas could render them
unusable prohibiting the timely completion and or limiting the long term use of the property.
A site copy will be available at the City Offices for the septic contractor.

.lob Site; Lot 7 Blk 1 Meadow -Wood Addition, Orono, Yinn.
Percolation teats and soil boiling were done on this lot in July of 1993
and at that time it was determine that there was two sites that are
suitable to locate mound systems on.
See the report dated8/9/96 fox' the details.
ed in the spring These sites should be rechecked p g to see if the percolation
h
rates are the same, percolation tests aan not be accurately done at th1,s
time due to the winter conditions.
However the land conditions are the same as was encounter in 1993
( no fill was added or excavtion occured on the proposed sites ) therefore
It can be assumed that the same percolation rates exist.
Borings were done and mmottled. soil was found at 18 inches , this is the
same level that was found in 1993•
Therefore at this time we will use the same percolation rates to size
out the mound system at this time, however future perc tests will be
done in the spring ( prior to installation) to verify this sizing
factor.
The ave. perc. rate in the primary site was 39.3 min/in. and. the depth
to n,ottl'd soil was at 18-24 inches.
The size of mound system needed fox' a 4 bedroom home 4-based-en
( based on 600 gal/day daily water useage and a perc . rate range of 4
46-60 min/in. the sizing factors ) would be the following size;
OVERALL SIZE 352E SQ.FT.
Tjpslope Length---79 ft. Downslope Length--93 ft. Width--41 ft.
Rock Bed Size---550 sq. ft. Width--10 ft. Length--55 ft.
Amount of materials needed ;
Sand---- 230 yds. 325 tons Ave. Depth--1 . 7 ft.
Rock-- 21 yds. 30 tons -1 . 0 ft.
Sandy Loam 40 yds --1 . 0 ft.
Topsoil---100 yds. ---9 inches
The above amounts could vary by plus or minus- 10 .
This mound must be pressurized therefore -'a pump tank. and a pump is needed ;
Size of pump tank--1000 gallon
Size of pump-- 40 g.p.m(must overcome at leastl.$,' ft. head press. )
Pumping Rate--:i73 gal/circle( 4 cycles/day)
An alarm system must be installed in the house to indicate pump failure
this must be both a sound and a light alarm system.

Size of septic tanks needed 2-1000 gallon sealed tanks
These tanks should be pumped out every 2-3 years
Phe present sites are ropoed off to prevent any construction from
compacting the sites , this prcocedure should be continued.
There is some concern that the alternate site might be distubed during,
construction due to the location of the house. Therefore another soil
borinw was done north of the primary site indicating the following results ;
SB-1A 0-16"Topsoil ( Black Loam) 10 Yh 2/1
16-60 " Park Frown Clay 10 • YR 3/4
"ottled soil was encounter at 26 inches.
herefore another mound system could be installed in this area
however the perc . tests will have to be done in the spring when the
frost is out of the ground to obtain accurate results.
* ,,otc the land slope in this area is 6 % , which conforms to the
local codes and the Finn. Rules 7080.

3134 130th Ave. N .W.
Coon Rapids , 'Finn.
lob Site; Lot 7 911c 1 Feadow -Wood Addition, Orono, Finn.
Percolation tests and soil boring were done on this lot in July of 1993
and at that time it was determine that there was two sites that are
suitable to locate mound systems on.
See the report dated8/9/96 for the details.
^hese sites should be rechecked in the spring to see if the percolation
r-tes are the same, percolation tests can not be accurately done at thl.s
time due to the winter conditions.
However the land conditions are the same as was encounter in 1993
( no fill was added or excavtion occured on the proposed sites ) therefore
it can be assumed that the Game percolation rates exist.
"orings were done and -mottled soil was found. at 18 inches , this is the
same level that was found in 1993•
Therefore at this time we will use the same percolation rates to size
out the mound system at this time, however future perc tests will be
done in the spring ( prior to irstallation ) to verify this sizing
factor.
The ave. Pere . rate in the primary site was 39. 3 min/in. and the depth
to mcattled soil was at 18-24 inches .
The size of mound system needed for a 4 bedroom home 4-based-en
( based on (00 gal/day daily water, useage and a Pere . rate range of 4
46-60 min/in. the sizing factors ) would be the following size;
0"FhATL ST7,F 352E S �.FT.
1Tpslope _Length- -79 ft. Downslope Length--93 ft. Width--41 ft.
Rock Sed Size---550 sq. ft. ' Width--10 ft. Length--55 ft.
Amount of materials needed ;
Srand---- 230 yds. 325 tons Ave. Depth--1 . 7 ft.
}dock-- 21 yds . 30 togs "----1 . 0 ft.
randy Loam 4.0 yds --1 . 0 ft.
-ropsoil ---100 yds . ---9 inches
-he above amounts could vary by plus or minus 10 .
'T'his mound must be pressurized therefore 'a pump tank. and a pump is needed ;
Size of pump tank--1000 gallon
Size of pump-- 40 g.p.m(must overcome at least 17 ft. head press . )
i'umping Hate--168 gal/cycle ( 4 cycles/day )
An alarm system must be installed in the house to indicate pump failure
this must be both a sound and a light alarm system.
501-1
�.�.;j. !'fir: E31
H.u. 0 Homebuilders Inc . Report ( cont. ) pg.-2
Size of septic tanks needed 2-1000 gallon sealed tanks
'These tanks should be pumped out every 2-3 years
The present sites are ropoed off to prevent any construction from
compacting the sites , this prcocedure should be continued,
There is some concern that the alternate site might be distubed during
construction due to the location of the house. Therefore another soil
boring was done north of the primary site indicating the following results;
SB-1A 0-16"Topsoil ( Black Loam ) 10 YR 2/1
16-60 " Park Prown Clay 10 , YR 3/4
r"ottled soil was encounter at 26 inches.
Therefore another mound system could be installed in this area
however the perc . tests will have to be done in the spring when the
frost is out of the ground to obtain accurate results.
* Note the land slope in this area is 6 which conforms to the
local codes and the r,'inn. Rules 7080.

with the local ( C1ity of 0rono )codes.
* Note ; The only two type of systems that are allowed is a
standard trench system or a pressuz,ized mound system.
Percolation rate results and mottled soil levels foil the following
lots.
Lot # 3 Site ,# 1 ave. percolation rate- 37.2 min/in.
mottled soil levels 13-16 inches
Site # 2 ave. perc . rate--43. 9 min/in.
mottled soil levels-14-20 inches
Lot # 4 Site # 1 ave. perm , rate 39. 3 min/in.
mottled soil levels 24-30 inches.
Site 2 ave. perc . rate 34. 3 min/in.

I-:ottled soil levels 16-22 inches.
mottled soil is consider the high seasonal saturated soil conditioms
that exmst during the wet seasons. The City Wf Orono On-Site
Sewage Codes require that the minnimum depth to mottled soil
be at 54 inches before a standard system can be installed.
Therefore the only systemsthat can be installed on the above lots is
