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.
*** DO NOT MAIL PAYMENT WITH THIS APPLICATION ***
2. Permits will be only issued 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.
4. The following inspections will be required for all septic systems:
A. Tank installation prior to covering.
B. Drainfield trench installation prior to covering. For mounds, inspection is required after
rough up, but prior to sand placement (sand must be jar tested for silt content) and
again during pressure distribution piping installation in the rock bed.
C. Final inspection to verify final cover depths and to verify that all pump station (where
required) components are functional and comply with codes.
5. MPCA licensed Installers or their DRP (Designated Responsible Person) shall be present
during all inspections.
A 24-HOUR NOTICE IS REQUIRED FOR ALL INSPECTIONS.

This on-site Sewage Treatment System is designed for a Type 1 four-bedroom home in accordance with the
Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
The periodically saturated soils were located at 22-30 inches(mottled soil).Due to the periodically
saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom
of the treatment area must be located at least 3'above the saturated soils.
All neighboring wells are greater than 100'from proposed treatment areas. ORONrO copy
The soils at a depth of 12"have a percolation rate averaging 4 MPI.
The existing septic tank must be abandoned.Two ;- . !!! 1: .;• _. • . ;, need_to be install----.�,
Option A the supply line goes around the ho Option B the plumbing must be redirected in the basement. 1
The supply line must be insulated under both driveways.
All new tanks need to be insulated if there is less than two feet of cover over the top of the tanks and a filter
installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance.
A new 1000 gallon lift station must 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 weatherproof enclosure. A
warning device must be installed with light and sound devices;this is in case of a pump failure.The
manifold and supply line must have back drainage to the pump chamber.The rock and fill materials must
be clean.The sod layer below the entire mounded area must be turned over.Just break up the sod and be
sure not to over work.
Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be
disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be
used;they may cause harmful damage to your septic system. It is recommended that you pump the
tank every year for 1 septic tank,every two years for two septic tanks.

5. Determine the Number of Perforation Spaces. Divide the Length of Laterals (Line 4)by the Perforation Spacing (Line 2)and
round down to the nearest whole number.
Number of Perforation Spaces = 48 ft 3 ft = 16 Spaces
6. Number of Perforations per Lateral is equal to 1.0 plus the Number of Perforation Spaces (Line 5).
Perforations Per Lateral = 16 Spaces + 1 = 17 Perfs. Per Lateral
Check Table I to verify the number of perforations per lateral guarantees less than a 10%discharge variation. The value is double if
the a center manifold is used.
7. Total Number of Perforations equals the Number of Perforations per Lateral (Line 6)multiplied by the Number of
Perforated Laterals (Line 1).
