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.

The periodically saturated soils were located at 26"-34"(mottied 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 aze greater than 100' from proposed treatment areas. The soils at a depth of 12"have a percolarion rate averaging 2 MPI. ORONO COPY The existing tanks must be abandoned. 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. Use 7/32 inch aerforations on t6e laterals. Keep all heaw Equipment off the proposed treatment azeas before during and after construction. A pumping chamber will need to be instailed 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 manifoid and supply line must have back drainage to the pump chamber.The rock and filt materials must be clean.T'he sod layer below the entire mounded area must be turned over.Just break up the sod and be sure not to over work. _Not6ing other than�rav water,(laundrv,showers.etc.) Human water and toilet tissue should be disaosed of into the seatic tanks. Garbaee disaosals are not recommended. Additives must not be used;thev mav cause 6armful damage to vour septic svstem. It is recommended that vou pump the tanks everv two vears.
