Co., MN <br /> A Complianc;e Inspection was completed for the existing on-site sewage treatment <br /> system locafied on this property for a remodeling to the home. The system consisfis of <br /> 2-1000 gallan septic tanks, 1-10G0 gallon pumping chamber & a pressurized mound <br /> system with a 10' x 65' rock bed. The sizing factor for a mound system is .83sq.ft./gal = <br /> f22 sq.ft. which would require a 10' x 62' rock bed, a 10' x 65' rock bed was found <br /> which is a,dequate for a 5 bedroom home. <br /> �oil boring #f�1 found mottled soil (redox features) at 2.5' below grade. Boring #3 found <br /> the original soil at elev.937.7 & the bottom of the rock bed at elev. 938.9 which leaves <br /> 1.2' of sand below the rock bed 8� a 3.7' separation from the bottom of the rock bed & <br /> redox featurE:s. Boring #2 found mottled soil at 1.7' below grade. Boring #4 found the <br /> original soil �t elev.936.7 & the b�ttom of the rock bed bed at elev. 939.0 which leaves <br /> 2.3' of sand below the rock bed & a 4' separation frorn the bottom of the rock bed & <br /> redox featur�:s. This system is in compliance with Minnesota Chapter 7080 rules. <br /> The tanks wE:re pumped by Elmer J. Peterson Co. &were found to be water tight. <br /> Nothing oth�r than gray water (laundry, showers, etc.) human waste & toilet tissue <br /> should be disposed of into the septic tanks. Garbage di�posals are not recommended, <br /> due to adding more solids & fine solids passing through to the system. Recommend to <br /> ORO:�� COPY <br /> 1 <br />
