Job No. 1004LT4 Desc: Site Plan on Lot 4, Block 1, Kokesh Farm
Dear Craig:
The following is a revised design for a septic system for a 5 bedroom house on the above referenced lot
using a mound system.
This is only a DESIGN of the on-site septic system. Otto Associates, Ine., does not represent nor warrant
the installation, operation, or proper function of this system for any period of time.
No construction should begin before these plans are approved by the Building Inspection Department for
the City of Orono.
Please note that we have marked off the septic treatment area. It is your responsibility to protect and
maintain these until after the construction is complete.
Enclosed are four copies, two for the building department, one for your contractor, and one for you.
If you have any questions, please call me.
Sincerely,
Otto Associates

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.
NOTICE TO INSTALLERS: Any changes to the approved plans must have prior approval of the
inspector (952-249-4600) Call for inspection 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 the primary and alternate sites are protected.
NO VEHICULAIZ TRAFFIC OF ANY KIND is allowed within 20'of tested drainfield sites ever.

GENERAL INFORMATION
This design is for a Type l, 5 bedroom home and in accordance with the Minnesota Pollution Control
Agency Standards and local ordinances.
A seasonally high water table was evidenced at 20 inches of depth in Soil Boring 10. The slope is about
3%.
The soils at a depth of 12 inches in Test Hole 10, 11 & 12 and have an average percolation rate of 20
minutes per inch. All neighboring wells are located more than 100 feet away from the proposed trea.tment
azea.
NOTES:
Keep all heavy equipment off the proposed treatment area before and after construction as much as
possible. The treatment area should be marked offbefore construction.
With proper installation and maintenance this system should have no problem in treating septic ef�luent
effectively.
It is recommended that the septic tanks be pumped every 2 years.
MOUND SYSTEM:
Flow: 5 bedroom= 150 gallon/day/bedroom 150 x 5 = 750 gallons per day.
750 GPD x 1.00= 750 square feet.
10 foot wide rock bed 75 feet long= 750 square feet
CONSTRUCTION EOUIl'MENT:
A rubber-tired tractor may be used for plowing or disking to prepare the soil surface but in no case shall
a rubber-tired tractor be used after the surface preparation is completed. A crawler or tract-type tractor
sha11 be used for mound construction.
SOIL SURFACE PREPARATION:
The discharge pipe from the pump to the mound area sha11 be installed prior to soil surface preparation.
The trench excavated to install the discharge pipe shall be carefully backfilled and compacted to prevent
seepage of ei�luent.
The total area selected for the mound, including that under the dikes, sha11 be roughened in order to
thoroughly break up any e�sting sod layers and to provide a suitable transition zone between the original
soil and sand layer of the mound. The area sha11 be roughened only when the moisture content of the soil
8 inches below the surface is drier than the plastic limit.
Surface preparation or roughening may be performed with a mold board plow, a disk plow, or a back hoe
using only the teeth. Mold boazd plow furrows shall be at least 8 inches deep, sha11 be thrown up s�ope and
sha11 run perpendicular to the slope. There shall be no dead furrow under the mound.
REVISED SITE EVALUATION REPORT for Lot 4,Block 1, Kokesh Fa.rm
Sewage Treatment System Page 3
Diskin� may be used for surface preparation as a substitute for mold board plowing in soils having
percolation rates faster than 15 minutes per inch(sandy loam)in the top 8 inch depth.
Back hoe teeth may be used to roughen the soil surface and break up the sod layer. Care must be taken so
as not to compact or puddle deeper soil layers. In no case shall any surface soil be exc�vated and removed
from the area.
Mound Construction shall proceed immediately after surface prepazation is completed. Every effort should
be taken to prevent rain from falling on the prepared soil surface.
(�ONSTRUCTION 1VLA'i'FR,LAi S �ND PROC'EDi7RF�;DISTRi�3iTTION OF EFFLUENT�
A minimum of 12 inches of soil defined as sand shall be placed where the filter material is to be located.
A crawrle,�ttactor with a blade or bucket shall be used to move the sand irno place. At least 6 inches of sand
shall be kept under the tra�ccks to minunize compacting of the plowed layer. The sand layer upon which the
filter material is plac� sha11 be level.
Sand is defined as a soil te3cture composed by weight of a least 25 percent of very coarse and medium sand,
varying in size from 2.0 to 0.25 mm, less than 50 percent of fine or very fine sand ranging in size between
0.25 and 0.05 mm, and no more that 10 percent of particles smaller that 0.05 mm.
A minimum depth of 9 inches of filter material (rock) sha11 be placed on the sand layer prior to installing
the distribution pipe.
Filter material is defined as clean rock, crushed igneous rock or similar insoluble, durable and decay-
resistarn material free from dust, sand,silt or clay. The size shall range from 3/4 inch diameter to 2 '/Z inch
diameter.
PRESSURE DISTRIBiJ'TION:
Effluent shall be distributed over the filter material by three 1 1/2 inch diameter perforated pipes under
pressure 72.5 feet long. Perforation holes shall be 1/4 inch diameter drilled in a straight line along the length
ofthe pipe. Hole spacing shall be 30 inches with 24 perforation per lateral. Holes sha11 be drilled straight
urto the pipe and not at an angle. A sharp drill shall be used and any burrs in the inside of the pipe shall be
removed. The perforated pipe laterals shall be installed level with the perforations downward.
The perforated pipe laterals shall be connected to a 2 inch diameter manifold pipe and shall have their ends
capped. The laterals sha11 be spaced 40 inches on center and at 20 inches from the edge of the filter
material.
The manifold pipe shall be connected to the supply pipe from the pump. The manifold shall be sloped
toward the supply pipe from the pipe.
Geo-Textile material shall be placed over the filter material.
Construction vehicles sha11 not be allowed on the filter material until backfill is placed.
REVISED SITE EVALUATION REPORT for Lot 4,Block 1,Kokesh Fann
Sewage Treatment System Page 4
Sandy loam soil shall be placed on the filter material to a depth of 12 inches in the center of the mound and
to a depth of 6 inches at the sides.
Six inches of topsoil shall be placed on the fill maxerial over the entire area of the mound. A grass cover
shall be established over the eirtire area of the mound. No shrubs shall be planted on the top of the mound.
Shrubs may be placed at the foot and side slopes of the mound.
The side slopes of the mound will be 4 feet horizontal to 1 foot vertical(4:1). This gentle slope will allow
easy mowing of the grass cover. The soil material at the toe of the dike should be slightly less permeable
. or somewhat tighter than the natural soil below the mound. This can be accomplished by selecting a finer
soil or by compaction.
Whenever mounds are located on slopes, a diversion shall be constructed immediately up slope from the
mound to intercept and divert runoff.
PiJMP AND COLLECTION TANK:
A pump shall be used to deliver effluent to the mound. The pump sha11 be cast iron or bronze fitted with
stainless steel screws or constructed of other sound, durable and corrosion resistant materials.
The pump installed will need to deliver 66.6 gallons per minute with a hea.d of at least 35 feet. An alarm
device shall be installed to warn of pump failwe. Install the pump control and a Meyers,Model D.L.V.
Audio Visual, Lo-Voltage alarm system or approved equal in a conspicuous place at the direction of the
owner.
Dosing Volume=25%of 750 g.p.d. = 188 gallons.
DRAINFIELD ROCK REOUIRED:
Based on 12 inches of rock, 27.8 cubic yards of rock would be required.
�AND REOUIRED:
Approxima.tely 174 cubic yards of clean sand for under mound is needed.
