NOTICE TO INSTALLERS: Any changes to the approved plans must have prior approval of the inspector(249-4600) Call for inspection 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 the primary and alternate sites are protected. NO VEHICULAR TRAFFIC OF ANY KIND is allowed within 20'of tested drainfield sites ever. ACCEPTED DENIED By the City of Orono subject to existing regulations and the following conditions: By: Chris Pence, On-Site Systems Manager Telephone(612)2494600 - Fax(612)2494616 Koch Soil Testing Box 81 Loretto, MN 55357 (612) 479-2637 Date 8/28/99 Name Ned Butterfield 3745 Watertown Rd. Orono,Minn.. Job Site;Above Address The present drainfield is bleeding out onto the surface therefore another site was tested to determine what type of system could be install and still comply with the local codes and with the Minn. Rules 7080. The area that was tested is located South of the present house. The average percolation rate in this area was 38.4 min/in. the depth to mottled soil was at 18 inches.. * See the enclosed percolation tests and soil borings for the details. *Mottled soil is consider the highsS� yrls that exist methe le t seasons (Fall and Spring).The Minn. RuleO80 state thatthe minimum depth to d soil must beat 48 inches or deeper before a trench drainfield can be installed. 'Therefore with the above information the only type of drainfield that can be installed in this area is a pressurized mound system and still comply with the current codes. The size of mound system needed for a 3 bedroom home would be the following size Sizing Factors : 1)Daily Water Usage --450 gal/day 2) Perc. Rate Range --46-60 min/in. ( CLay Loam Soil Factor) 3)Land Slope--4% Overall Size--2870 sq.$.. Upslope Length--65 ft. Downslope Length---75 ft Width---41 $ .(Upslope-12$Rock-10 ft Downslope--19 ft). * Absorption Width-- 271 Rock Bed Size--410 sq. ft Length--41 $ Width--10$ Amount of materials needed; Sand--165 yds. 230 tons Ave. Depth--1.7$ Rock-- 16 yds 23 tons -- 1.0$ Sandy Loam-- 30 yds. --- 1.0$ Topsoil -- 85 yds. --- 9 -- 12 inches *The above amounts could vary by plus or minus 10%. 'Ibis mound must be pressurized therefore a pump tank and a pump is needed; Size of pump tank----1000 gallon Size of pump ----30 &p.m(must overcome at least 13.5 $ of head press.) pumping Rate --144 gal/cycle (4 cycles/day) An alarm system must be installed in the house to indicate pump failure,this must be both a sound and alight alarm system. Size of septic tanks needed;Two-1000 gallon sealed tanks. These tanks should be pumped out every 2 to 3 years,this practice will enhance the life of the mound system. This site should be roped off to prevent construction traffic from compaction the site which will result in ruining the site. Site Evaluator Robert A.
