*** DO NOT MAIL PAYMENT WITH TIIIS APPLICATION***
GENERAL INSTRUCTIONS
1. Applications for septic system permits may be mailed or submitted in person at the City
Offices; however, permits will not be mailed out. The permit must be picked up in person
at the City Offices and work must not begin unless the permit card is on the job site.
2. Permits will be issued only to contractors holding a Minnesota Pollution Control
Agency(MPCA) Septic System Installers License.
3. All work must be done in accordance with the approved septic system design. Design reports
are not considered approved unless accompanied by the "City of Orono Septic System
Approval" cover sheet signed by the City Inspector.
4. The following inspections will be required for all septic systems:
A. Pre-installation site inspection to include inspector, installer, and general contractor.
B. Tank installation prior to covering.
C. Drainfield trench installation prior to covering. For mounds, inspection is required after
rough up but prior to sand placement (sand will be jar tested for silt content), and again
during pressure distribution piping installation in the rock bed.
D. Final inspection to verify proper final cover depths and to verify that all pump stations
(where required) components are functional and comply with codes.
ti. Individual holding MPCAInstallers License shall be present during all inspections, A 24-hour
notice is required for all inspections.

System Specifications
Pump Tank:
• Plumbing shall be run up into riser and back down with a 1/4"
drain back hole.
• Floats are to be installed on a float tree, separate from the
piping connected to the pump.
• A 2.5" Electrical conduit is to be used.
• The 2" force main shall be sleeved with 4" sch 40 and sealed
with 4x2 Fernco, from the pump tank to original soil.
An "Effluent Filter" is to be installed in the outlet of the second tank. If
a "Zabel" PDS-PF-1.5/2.0 Pressure Filter or a "Sim-tech" Pressure Filter
is a better option it may be installed in the supply line in the pump
chamber, and to be easily accessible from the ground surface for
cleaning. (The pump alarm will sound when this filter clogs)
All run-off water is to be diverted away from the tanks and drainfield
areas
Plastic bolt down manhole covers are to be used and left at grade level
for maintenance access.
Blowout valves are to be installed on the end of all pressurized laterals.
These will need to be in a protective housing and accessible from
surface grade.
Pressure rate glue joint fittings must be used.
No Fernco's will be used in pressure lines.
If the septic tanks are less than 3' deep the covers are to be insulated
with 2" high-density foam

D. ROCK LAYER DIMENSIONS
1. Multiply average design flow(A)by 0.83 to obtain required area of rock layer:Item A x 0.83=
600 gpd x 0.83 fegpd= 498.0 ft2
2. Determine rock layer width =0.83 ft2/gpd x Linear Loadin' Rate(LLR)(see LLR chart)
0.83 ft2/gpd X 12 = 10.0 ft
LLR Chart
Perk Rate LLR
<120 MPI <=12
>=120 MPI <=6
3. Length of rock layer=area divided by width=
498 ft2 I 10 feet= 50.0 feet
E. ROCK VOLUME
1. Multiply rock area by rock depth to get cubic feet of rock
498 X 1 ft= 498.0 ft3
2. Divide ft3 by 27 ft3lyd3 to get cubic yards
498.0 ft3 / 27 = 18.4 yd3
3. Multiply cubic yards by 1.4 to get weight of rock in tons;
18.4 yd3 X 1.4 ton/yd3 = 25.8 tons
F. ABSORPTION WIDTH
1. Abso tion width uals absorption ratio(see Figure D-33)times rock layer width
2 x 10.0 ft = 20.0 ft

G. MOUND SLOPE WIDTH&LENGTH(Greater than 1%)
1, Downslope absorption width=absorption width minus rock layer width
20 feet - 10 feet= 10 feet
2. Calculate mound size
UPSLOPE
a. Determine depth of clean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1)
3 ft - 1.8 ft= 1.2 feet
b.Mound height at the upslope edge of rock layer=depth of clean sand for separation(G2a)
at upslope edge plus depth of rock layer(1 foot)to depth of cover(1 foot)
1.2 ft+1 ft+1 ft= 3.2 feet
c. Upslope berm multiplier based on land slo.e see figure 0-34)
Select berm multiplier of 3.45
d. Upslope width=berm multiplier(G2c)times upslope mound height(G2b):
3.45 x 3.2 ft = 11.0 feet

ft x ft = 0 ft2 41 W
Length
B. Circle area=3.14 x radius?
3.14 x zft = 0.0 ft2
C. Get area from manufacture ft2 Radiu
2. Calculate gallons per inch
There are 7.5 gallons per cubic foot of volume,therefore multiply the area(1A,8 or C)
times the conversion factor and divide by 12 inches per foot to calculate gallon per inch.
Surface area x 7.5/12= 0 ft2 7.5 / 12inlft = 21.5 gallon per inch Legal Tank:
500 gallons or
3. Calculate total tank volume 100%the daily flow
A. Depth from bottom of inlet pipe to tank bottom 47 in or Alternating Pumps
B. Total tank volume=depth from bottom of inlet pipe to tank bottom(3A)x gal/in(2) -A..I:rstimoted Sewage llows in Gallors per De- '-..--

5. Calculate total pumpout volume
A. Select pump size for 4-5 doses oar day. Gallon per dose=gpd(see Figure A-1)l doses per day=
600 ,gpd / 4 doses/day = 150 gallons
B. Calculate drainback
1. Determine total pipe length 40.0 ft II
2. Determine liquid volume of pipe, 0.17 gal/ft(see figure E-20)

7, Calculate volume for alarm(typically 2-3 inches)
Alarm depth(inch) x gallon/inch(2) = 3 in x 21.5 gal/in = 64.5 gal
8. Calculate total gallons=gallons over pump(4)+gallons pumpout(5C)+gallons alarm(7)
