Applications for septic system permits may be mailed or submitted in person at the City offices; however, permits will not be maited 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.

R6EY THIS PLAN S8't ON SITE AT ALL TIMES March 1 2003 Revised July 23, 2012 Re: Soil Borings, Percolation Tests, System Design. We were retained by Rachel Brady to provide criteria for the design and instailation of an on-site sewage system for the property located at 424 Deborah Dr in the City of Orono This design is based on a four bedroom;type one, single family home with m�imum flow of 600 gallons per day. A total of 6 soil borings and 2 perc tests were done. From these tests it was determined that a high water table exists at a depth of 30 to 34 inches below the ground surface_ T'he hi�h water table determines that only a mound type drainfield may be installed. The soils on this site are Hamel Lc�am as identified by the Hennepin County soil map. The system sha11�onsist of the following; -One new 1500 gailan septic tank. -One New l 250 ga:llon septic tank. -One new 1250 galion pump chamber -550 square feet of rock, bed mound type drainfield. -Upslope length of 79 feet -Downslope length of 95 feet -Width of 41 feet Materials needed for the mound canstruction include: -Clean washed sand 170 cubic yards -1 foot deep-upsl4pe -l.b feet deep-downslope -Clean washed rack 21 cubic yards -Sandy Loam soil af 25 cubic yards -Top soil of 140 cubic yards T'he mound must be pressurized,therefore a pump must be installed that can pump 42 gallons per minute wiih a total head of 42 feet. 1�n alaxm systern must also be installed to warn of pump failure. A T'�ank efIluent filter shall lled to fiiter eii�iuent�d�extend the life�ke system. Thi �s-f�i t�er shali be maintain��.�s naeeded. � � � � �'� `— � ti`^P A s s .� l� -4-0 5�--� �� w i�re -�-o ,� I a �wi �'3 c�X �� . All tanks that have less than twa feet of cover shall have the lids insulated. Cleanouts shall be instalied at each lateral pipe in the mound. They shali he instatled in such a way as to have access to the surface and protected from damage, such as an irrigation box. The entire area that is to be used for the drainfield shall be protected from any traffic to prevent any compaction prior to and during construction. Failt3re to do so shall result in this design becoming VOID. At that time the site may have ta be tested again or an aiternate site located and testing done. All neighboring wells are located greater than 1Q0 fee#from the proposed drainfield site. The existing tank must be abandoned because it is to close to the well. Additives of any kind must not be used along with any chlorine or antibacterial solutions. They may cause damage to the system. Water softeners must be diverted vut vf the system this will prolong the life, and protect the concrete component of the system We recommend that there be no traffic Qf any kind an the mound area especially in the winter time as it may cause freezing. It is recommended to pump and service the septic tanks every two to three years for maximum life of the system. All requirements of this design must be fallowed in order for the system to perform to the design capabilities and for this design to be valid. This design is in compliance with local codes and Minnesota Pollution Control Chapter 7080 as of the date listed above.
