Permits will be only issued to contractors holding a Minnesota Pollution Control Agency (MPCA) Septic System Install�ers 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, b�t 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 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. . All neighboring wells are located greater than 100' away from proposed treatment area. The existing mound rock bed is 41 foot long as per city records. The rock bed must be extended 22 feet for a total of 63 feet of rock bed.This will conform to a type 1 five bedroom house.The existing rock bed does conform to the three foot separation to the saturated soils. The soils at a depth of 12"have a percolation rate averaging 13 MPI. The existing septic tanks must be abandoned and two new 1300 gallon septic tanks need to be installed. Al(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 1300 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. Keep all heavv equinment off of the pronosed treatment areas before and after construction The area around both sites must be fenced off bv the contractor before any construction begins This DesiEn is not valid and the Svstem will need to be relocated if failure to protect the areas arouosed 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 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 tanlc eve�r two years for two tanks.
