CITY OF ORONO — SEPTIC SYSTEM PERMIT APPLICATION 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.

The periodically saturated soils were located at 10"-28"(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 soils at a depth of 12"have a percolation rate averaging 11 MPI. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A filter needs to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. Two 1250 gallon septic tanks need to be installed. Care should be taken when installing the rock bed.It must be greater than 50 feet from the existing well. A 1250 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 pumping chamber. Keep all heavy equipment off of the proposed treatment areas before,during and after construction. The area around both sites must be fenced off by the contractor before any construction begins. 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 septic tanks every two years.
