The system consists of 2- <br />1300 gallon septic tanks, 1 -1300 gallon pump tank, a pressurized mound system <br />with a 10' x 66' rock bed, built in 2010 for a 5 bedroom home. <br />Soil boring #1 found mottled soil (redox features) at 2.7' into the original soil & the <br />original soil at elev. 102.5 & the bottom of the rock bed at elev. 105.2 leaving 2.7' of <br />sand below the rock bed & a 5.4' separation from the bottom of the rock & redox <br />features. Soil boring #2 found mottled soil at 2.1' into the original soil & the original <br />soil at elev. 102.6 & the bottom of the rock bed at elev. 104.9 leaving 2.3' of sand & a <br />4.4" separation. This system meets the required 3' separation from the bottom of <br />the rock bed. <br />The tanks were pumped by Kothrade Sewer, Water & Excavating, Inc. & were found <br />to be compliant. <br />Nothing other than gray water (laundry, showers etc.) human waste & toilet tissue <br />should be disposed of into the septic tanks. Garbage disposals are not <br />recommended due to adding more solids & fine solids passing through into the <br />system. Iron filters are also not recommended & should be diverted out of the <br />system. Excessive amounts of soaps, antibacterial soaps, cleaning agents, shower <br />cleaners used every shower & chlorine agents may kill the bacteria you need living <br />in the system. Additives are not recommended. Recommend to pump & clean you <br />tanks through the manhole by a certified pumper every 2 years. Check with your <br />pumper to set up a schedule. <br />This certificate of compliance is no guarantee that this system will continue to <br />function indefinitely. <br />Steven B. Schirmers <br />
