No 627 - State License#394 - Phone 763-497-3566 - Fax 763-497-5011 <br /> www.sptesting.wastewater@comcast.net- schirmerswastewater.com <br /> April 10, 2021 <br /> Daron Meyer <br /> 460 Sussex Lane <br /> Orono, MN <br /> A Compliance inspection was completed for the existing on-site sewage treatment <br /> system located on this property for the sale of the home. The system consists of 2- <br /> 1250 gallon septic tanks, 1 -1250 gallon pump tank, a pressurized mound system <br /> with a 10' x70' rock bed, built in 1995 for a 5 bedroom home. <br /> Soil boring #1 found mottled soil (redox features) at 1.7' into the original soil & the <br /> original soil at elev. 97.7 & the bottom of the rock bed at elev. 99.1 leaving 1.4' of <br /> sand below the rock bed & a 3.1' separation from the bottom of the rock & redox <br /> features. Soil boring #2 found mottled soil at 1.2' into the original soil & the original <br /> soil at elev. 96.8 & the bottom of the rock bed at elev. 99.3 leaving 2.5' of sand & a <br /> 3.7' separation. This system meets the required 3' separation from the bottom of the <br /> rock bed. <br /> The tanks were not pumped due to road restrictions. <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.
