The required setback is 75 ' , but a 50 ' setback will be allowed as no other options are viable . The homeowner request to use a Class 1 aerobic treatment system is also approved as submitted. THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A permit must be issued to a licensed septic contractor prior to installation. A list of currently licensed septic contractors is enclosed. NOTICE TO INSTALLERS: Any changes to the approved plans and specs must have prior approval of the Inspector (473-7357). Call for inspections 24 hours in advance. ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain in place until final site grading. Approval to pour footings will not be granted until ttie Inspections Department has verified that primary and alternate sites are adequately protected. NO VEHICULAR TRAFFIC OF ANY KIND (cars, trucks, earth moving equipment, etc.) is allowed within 20' of tested drainfield sites either before or after system construction. Compaction of these areas could render them unusable prohibiting the timely completion and or limiting the long term use of the property. A site copy will be available at the City Offices for the septic contractor. CITY OF ONO By Step en'� an, On-site Syst s Manager TELEPI iONE—473-7357• FAX-473-0510 � �7-P TESTING� �NC. Steven B.

Due to this site having no additional area to treat septic effluent & to assure long term survival of the system, recommend to install a Class 1, Multi-Flo Aerobic Wastewater Treatment System. The highly treated, filtered effluent produced by the Multi-Flo is over 95% free of the normal sewage contaminants that cause the progressive failure of conventional systems. The unit will be a 0.6, 600 gal/day. A trash trap is installed in front of the Multi-Flo. The unit requires to be serviced 2 times a year which will be done by Schirmers Wastewater Treatment Systems, Inc. A 2 year service & parts warranty comes with the purchase of the unit. After that time, the homeowner is required to carry a Service Contract at $100.00 a year (1996 price). A report is sent to the homeowner, city, MPCA & Multi-Flo yearly. The cost for this unit is $3769.80 (includes tax) & $250.00 for shipping. Total cost is $4019.80,this includes the installation. The two new tanks proposed would be eliminated & replaced with one 500 gallon trash trap. The installer for the Mound System would need to dig the hole for the Multi-Flo, 1/2yd. of pea rock for under the Multi-Flo to level it & the wiring for the aeration motor. If you have any questions, please call. Thank You, �(�� Deb Schirmers 1 � . `-P TES TING� I NC. Steven B.

Orono, Henn. Co., MN This on-Site Sewage Treatment System is Designed for a Type 1, four bedroom home, in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. This site has an existing system consisting of two tanks and trenches or a seepage bed. Soil Borings indicate mottled soil less than 3' below the ground surface which would put the bottom of the system less than 3' away from the saturated soil & is classified as failed. The soils on this site are SCS soifs mapped - HbD - Hayden loam bordered by - Ha - Hamel loam.. The seasonally saturated soils were located at 16" to 20" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at feast 3' above the saturated soils. Due to the limited space available on this lot, the system will need to be less than 75' away from Long Lake (Recreational Lake). A 50' setback will be needed and will require a variance from the City of Orono. The soils at a depth of 12" have a percolation rate averaging 2.1 mpi. The system is Designed for the type of soil using a sizing factor for clay loam. A 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 weather proof enclosure. A warning device must be installed with a light and sound device, this is in case of a pump failure. 1 . � r ' The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be tumed over, just break up the sod, be sure not to over work. All neighboring wells are located greater than 100' away from the proposed treatment area. Keep aii heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid &the system will need to be relocated if failure to protect the areas proposed 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 waste &toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended, due to adding more solids 8�fine solids passing through to the system. Excessive amounts of soaps, cleaning agents &chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend to pump & clean your tanks through the manhole by a certified pumper every 2 years. Check with your pumper to set up a schedule. �_� . Steven B.
