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.

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. A small retaining wall will need to be built on the north east end of the system to stop the toe from overlapping the driveway.This is not part of the absorption area. All neighboring wells are greater than 100 feet from proposed treatment areas. ORONO COPY The soils at a depth of 12"have a percolation rate averaging 3 MPI. The existing septic system does not conform to the state code chapter 7080. The existing tanks must be abandoned.Two new 1000 gallon septic tanks need to be installed. The supply line must be insulated and sleeved under the driveway. All 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.The manifold and supply line must have back drainage to the pump chamber. 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 tanks every two years.

Friction Loss in Plastic Pipe per 1008 from Table I: 45 20.5 5.0 50 6.1 Friction Loss= 2.23 ft per 1008 of pipe 55 7.3 60 8.6 F. Determine Equivalent Pipe Length from pump discharge to soil dispersal area discharge 65 10.0 point. Estimate by adding 25%to supply pipe length for fitting loss. Supply Pipe Length 70 11.4 (D.2) X 1.25=Equivalent Pipe Length 75 13.0 20 85 16.4 ft X 1.25 = 25.0 ft 95 20.1 G. Calculate Supply Friction Loss by multiplying Friction Loss Per 100ft (Line E)by the Equivalent Pipe Length (Line F)and divide by 100. Supply Friction Loss= 2.23 ft per 100ft x 25.0 ft + 100 = 0.6 ft H. Total Head requirement is the sum of the Elevation Difference (Line A),the Distribution Head Loss(Line B),Additional Head Loss(Line C),and the Supply Friction Loss(Line G) 7.0 ft 5.0 ft + E - ft + 0.6 ft = 12.6 ft 3. PUMP SELECTION A pump must be selected to deliver at least 29 GPM(Lime 1 or Line 2)with at least 13 feet of total head.
