OWNER: Lawrence Anderson GENERAL CONTRACTOR: SEPTIC CONTRACTOR: SITE EVALUATOR: Koch' s Soil Testing REPORT DATE: not provided The City of Orono has Approved your on-site system design as of October 26, 1993 (approved-disapproved) (date) with the following comments: The primary drainfield site is approximately 15 ' from the property line. The required 20 ' setback must be verifipd at the time the system is installed. 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 the 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 ORONO BY AA/ / G, s 7- �� ,S /,r1aLf--�- Stephen eckman, On-site ystems Manager TELEPHONE-473-7357• FAX-473-0510 Koch's Soil Testing P.O. Box 81 Loretto, MN 55357 TO (612) 479-2637 To: Larry Anderson 1909 Shorewood Ln H 472-6262 Mound, Mn 55364 W 472-5580 Job: 745 Orchard Park Rd GENERAL INFORMATION This on site sewage treatment system is designed for a type I 4 bedroom home or 600 gal/day maximum. Construction should be started only after reviewal by local building inspector and after obtaining the permit. Construction should be done in accordance with the Minnesota Pollution Control Agency charter 7080 and local ordinances by a M.P.C.A. certified contractor. The soils on this site are mapped as Erin clay loam. Mottling indicates a seasonally saturation soil at 28" . Therefore a pressurized mound will need to be installed. The mound rock bed must be installed at least 3 ' above this seasonally saturated soil. , The soils at a depth of 12" have a percolation rate averaging 400Iminutes per inch and are adequate for treating septic effluent. NOTES Keep all heavy equipment off the proposed treatment area before and after construction as much as possible. The treatment area must be marked off before construction. SOIL SURFACE PREPARATION The discharge pipe from the pump ic) the mound area shall be installed before soil surface prepa'.ation. The trench excavated to install the discharge pipFi shall be carefully backfilled and compacted to prevent se,,Inage of effluent. The total area selected for the mound, including that under the dikes, shall be roughened to thoroughly break up any existing sod layers and to provide a suitable transistion zone between the original soil and sand layer of the mound. The area shall be roughened only when the moisture content of the soil 8 inches below the surface is drier than the plastic limit. Back hoe teeth may be used to rtughen the soil surface and break up the sod layer. Care must to taken so as not to compact or puddle deeper soil layers . Tn no case shall any surface soil be excavated and removed „_rom the area. CONSTRUCTION MATERIALS AND PROCEDURES A minimum of 12" of soil defined as sand shall be placed where the filter material is to be located. A crawler tractor with a blade or bucket shall be used to move the sand into place. At least 6 inches of sand shall be kept under the tracks to minimize compacting of the plowed layer. The sand layer upon which the filter material is placed shall be level. Sand is defined as a soil texture composed by weight of at least 25 percent of very coarse and medium sand varying in size from 2 . 0 to 0.25mm, less than 50 percent of fine or very fine sand ranging in size between 0.25 and 0. 05 mm and no more than 10 percent of particles smaller than 0 . 05mm. A minimum depth of 9 inches of filter material (rock) shall be placed on the sand layer under the distribution pipe. Filter material is defined as clean rock, crushed igneous rock or similar insoluble, durable and decay resistant material free from dust, san: , silt, or clay. The size shall range from 3/4 inch diameteJ to 2 1/2 inch diameter. PRESSURE DISTRIBUTION Effluent shall be distributed over the filter material by three 1 .5 inch diameter perforated pipes under pressure 53 ' long. Perforation holes shall be 1/4 inch diameter drilled in a straight line along the length of the pipe . Hole spacing shall be 36 inches with 19 perforation per lateral . Holes shall be drilled straight into the pipe and not at an angle. A sharp drill shall be used and any burrs inside the pipe shall be removed. The perforated pipe laterals shall be installed with the perforations downward. The perforated pipe laterals shall have their ends capped and shall then be connected in the center to a 2 inch diameter manifold. The laterals shall 3e spaced 40 inches on center and at 20 inches from the edge of the filter material . The manifold pipe shall be connected to the supply pipe from the pump. The manifold pipe shall be sloped downward to drain or buried deep to prevent freezing. Geo-Textile material shall be placed over the filter material . Sandy loam soil shall be placed on the filter material to a depth of 12 inches in the center of the mound. and to a depth of 6 inches at the sides . Six inches of topsoil shall be placed on the fill material over the entire area of the mound. A grass cover shall be established over the entire area of the mound. No shrubs shall be planted on top of the mound. Shrubs may he placed at the foot and side slopes of the mound. Whenever mounds are located on slopes, a diversion shalt be constructed immediately up slope from the mound to intercept and divert runoff . Nothing other than gray water, (laundry, showers etc . ) human waste and toilet tissue should be disposed of in the system. It should never exceed the 600 daily design flow, otherwise solids and sludge will be flushed on through the absorption field plugging the soil. Garbage disposal and powdered soaps add sludge to the tank and are discouraged. Frequent pumping of the tanks is insurance against premature plugging and failure of your system-' Under ordinary conditions it is recommended to pump a two tank system every two years and every year for a one tank system. I recommend that you either monitor the sludge level or have your pumper schedule you for regular routine pumping. Ingleside Engineering 7j/1-(4...
