OWNER: Mark Supaala GENERAL CONTRACTOR: Vintage B ui l de n&EPTIC CONTRACTOR: SITE EVALUATOR: Koch ' s Soil Testing REPORT DATE: October 8, 1993 The City of Orono has Approved your on-site system design as of October 12, 1993 (approved-disapproved) (date) with the following comments: A grinder station will be required to lift the effluent from the basement to the first tanks . Also, extra care must be taken to prevent compaction of the alternate site which is adjacent to the primary site. 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 ter,• '71- 1 Stephen feckman, On-site Systems Manager TEL,EPIIONE-473-7357 • FAX-473-0510 Koch's Soil Testing P.O. Box 81 Loretto, MN 55357 Vintage Builders Inc . Tel: (612) 479-2637 10/8/93 8401 73rd Ave. N Suite 90 Irpls . Minn. Job Site; Lot 1 , Blk 2 , Rolling Meadows Addition, Orono , Minn. Percolation tests amd soil borings were done on the above lot in 5/13/88 and on 11/29/90. It was determine that a mound system would be needed on this lot due to the mottled soil levels at 18-26 inches and the percolation rates were 72 min/in and 62. 7 min/in. The City of Ororno requires that the minnimum depth to mottled soil be at 54 inches and the maximum allowable perc. rate be 60 min/in. before a standard,trench system can be installed . v The size of mound system needed for a 5 bedroom home ( based on 750 gal/day daily water useage and •a perc . rate 72 min/in. the sizing factors ) would be 92 ft. hong'-on the upslope, 128 ft. long on the downslope and 62 ft. wide. The size of the rock bed needed would be 19 ft. wide by 68 ft. long ( 680 sq. ft. ) or 37 tons of rock is needed . See the enclosed design data for the specifications for the proposed system. This mound must be presssurized therefore a pump tank ( 1250 gallon) and a pump( 50g.p.m.- 214 gal/cycle- 4 cyc ;es/day) must be installed . An alarm system ( both a sound and a light alarm ) must be installed in the house to indicate pump failure. Two 1250 gallon sealed septic tanks must be installed , these tanks should be pumped out evry 2-3 years . every Only clean wash sand should be used in this mound , therefore this sand should be ♦:checked out by the local inspector to make sure it meets the specifications . All construction traffic must be kept off both sites to avoid compaction of the soils which will result in ruining the sites. Therefore both sites should be roped off by the builder.
