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.
5. Individual holding MPCA Installers License shall be present during all inspections. A24-hour
notice is required for all inspections.
NOTE: Applicant must initial all spaces. Fill in all appropriate blanks and check all appropriate

Orono, Henn. Co., MN
This site has an existing mound system which is surface discharging septic effluent at
the rock bed. Soil borings through the mound found the sand fill to be moist but not
saturated. The sand fill below the rock bed is a loamy sand, clean washed medium
sand is required for mound construction. A quart jar test was completed finding 1-1/8" of
sediment over the 2" of sand in the jar, 1/8 of sediment is allowed for mound fill sand.
To adequately treat septic effluent, a new mound system will need to be installed.
Surface discharging is classified as an imminent health hazard which must be repaired
or disconnected within 10 months or the City's required period, whichever is less.
This on-site sewage treatment system is designed for a Type 1, three bedroom home, in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances.
The soils on this site are SCS soils mapped - LrB - Lester loam. The seasonally
saturated soils were located at 16" to 20" (mottled soil). Due to the seasonally saturated
soils, a Pressurized Mound System will need to be installed to treat septic effluent. The
bottom of the treatment area must be located at least 3' above the saturated soils.
The soils at a depth of 12" have a percolation rate of 4.9 mpi.
The top of the tanks are approximately 6' to 6-1/2' deep. Due to the depth of the tanks,
ground water infiltration may also be part of the failure for this system. The tanks will
need to be inspected and certified as water tight. If the tanks are not water tight, new
-tanks will need to be installed. The tanks will also need to be verified they meet the 50'
setback from the existing well.
1
A 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. Be 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. Iron filters must be diverted out of the
system. Garbage disposals are not recommended, due to adding more solids &fine
solids passing through to the system. Excessive amounts of soaps, anti-bacterial
soaps, cleaning agents & 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.
