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.

The periodically saturated soils were located at 14-24 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. The existing septic system does not conform to the state code chapter 7080 All neighboring wells are greater than 100' from proposed treatment areas. The soils at a depth of 12" have a percolation rate averaging 3.6 MPI. The existing septic tanks must be abandoned and a minimum two new 1300 gallon and 1000 septic tanks need to be installed. All new tanks need to be insulated if there is less than two feet of cover over the top of the tanks. Clean outs must be installed on the end of the laterals for maintenance. A 1000 gallon 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 weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of a pump failure. A flow measurement device must be installed.Including but not limited to a water meter,event counter,running time clocks or electronically controlled dosing. 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 two years for two septic tanks.

OSTP Pressure Distribution ikitMinnesota Pollution UNIVERSITY Design Worksheet OF MINNESOTA 'Z\� Control Agency 12. Calculate the Square Feet per Perforation. Recommended value is 4-11 ft2 per perforation. Does not apply to At-Grades a. Bed Area = Bed Width (ft) X Bed Length (ft) 10 ft X 50 ft = 500 ft2 b. Square Foot per Perforation = Bed Area divided by the Total Number of Perforations. 500 ft2 ÷ 51 perforations = 9.8 ft2/perforations 13. Select Minimum Average Head: 1.0 ft 14. Select Perforation Discharge (GPM) based on Table: 0.74 GPM per Perforation 15. Determine required Flow Rate by multiplying the Total Number of Perfs. by the Perforation Discharge. 51 Perfs X 0.74 GPM per Perforation = 38 GPM 16.
