GENERAL INSTRUCTIONS ORONO COPY
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.
13. 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.
5. Individual holding MPCA Installers License shall be present during all inspections. A 24-hour
notice is required for all inspections.
NOTE: Applicant must initial all spaces. Fill in all appropriate blanks and check all appropriate

CA pumping chamber will need to be installed to lift the effluent to the treatment area.
)'
The power supply and switches must be located outside the manhole and pumping
chamber in a weather proof enclosure. A warning device must be installed with a light
and sound device, this is in case of a pump failure.
The manifold and supply line pipe must have back drainage to the pumping chamber.
The distribution pipes shall have their ends capped. sure the rock and sand fill
material are clean. The sod layer below the entire mounded area must be turned over,
just break up the sod, be sure not to over work.
All neighboring wells are located greater than 100' away from the proposed treatment
area.
Keep all heavy equipment off of the proposed treatment!area before and after
construction. The treatment area should be marked off before construction. This
Design is not valid &the system will need to be relocated if failure to protect the areas
proposed for On-Site Sewage Treatment occurs.
With proper installation and maintenance, this system should have no problem in
treating septic effluent effectively.
Nothing other than human waste, toilet tissue, laundry, showers, water softener etc.
should be disposed of into the septic tanks. Recommend Iron filters be diverted out of
the system. Recommend to divert the water softner also if the iron filter is diverted.
Garbage disposals are not recommended, due to adding more solids &fine solids
passing through to the system. Excessive amounts of soaps, antibacterial soaps,
cleaning agents, shower cleaners used every shower&!chlorine agents may kill the
bacteria needed to treat septic effluent Additives are not recommended. Recommend
to pump & clean your tanks through the manhole by a certified pumper every 2 years.
Check with your pumper to set up a schedule. Recomrriend laundering be limited to 3
to 4 loads per day.

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=
750 gpd x 0,83 ft21gpd= 622.5 ft2
2. Determine rock layer width =0.83 ft2/gpd x Linear Loading 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=
622.5 ft2 / 10 feet= 62.5 feet
E. ROCK VOLUME
1. Multiply rock area by rock depth to get cubic feet of rock
622.5 X 1 ft= 622.5 ft3
2. Divide ft3 by 27 ft3/yd3 to get cubic yards
622.5 ft3 / 27 = 23.1 yd3
3. Multiply cubic yards by 1.4 to get weight of rock In tons;
23.1 yd3 X 1.4 ton/yd3 = 32.3 tons
F. ABSORPTION WIDTH
1. Abso I tion width e.uals absorption ratio(see Figure D-33)times rock layer width
2.4 x 10.0 ft = 24.0 ft
G. MOUND SLOPE WIDTH&LENGTH(Greater than 1%)
1. Downslope absorption width=absorption width minus rock layer width
24 feet - 10 feet= 14 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 - 1.5 ft= 1.5 feet
b.Mound height at the upsiope edge of rock layer=depth of clean sand for separation(G2a)
at upsiope edge plus depth of rock layer(1 foot)to depth of cover(1 foot)
1.5 ft+1ft+1ft= 3.5 feet
c.Upslope berm multiplier based on land ; ••= see figure D-34)
Select berm multiplier of 3.33
d.Upsiope width=berm multiplier(G2c)times upsiope mound height(G2b):
3.33 x 3.5 ft = 11.7 feet
