Co., MN <br /> A Compliance inspection was completed for the existing on-site sewage treatment <br /> system located on this property. The system consists of a 500 gallon trash trap, 500 <br /> gallon Multi-Flo treatment system, a 1500 gallon pumping chamber with a timer&an <br /> At-Grade system sized for a 2 bedroom home, 256 gal/day installed 8-4-1995. <br /> Soil boring #1 found mottled soil (redox features) at 38" below the ground surface. <br /> Boring#2 found mottled soil at 36" into the original soil. An At-Grade system is placed <br /> at the original soil leaving a 3' separation from the bottom of the system& redox <br /> features. This system is in Compliance with Minnesota Chapter 7080 rules. <br /> The tanks were pumped &found to be compliant. The cover of the electrical box was <br /> damaged &was rplaced. <br /> The Multi-Flo system requires a yearly service contract which has been in place since <br /> the system was installed with Schirmers Wastewater Treatment Systems. A new <br /> aerator was also installed at this time. The yearly cost for the service is $180.00 (2012 <br /> price). The unit is serviced in the spring &fall. <br /> Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. <br /> should be disposed of into the septic tanks. Iron filters must be diverted out of the <br /> system. Recommend to divert the water softner also. Garbage disposals are not <br /> recommended, due to adding more solids &fine solids passing through to the system. <br /> Excessive amounts of soaps, anti-bacterial soaps, cleaning agents, shower cleaners <br /> used every shower&chlorine agents may kill the bacteria needed to treat septic <br /> effluent. Additives are not recommended. The trash trap, Multi-Flo and pumping <br /> chamber will need to be pumped out when the retable solids reach 50% in the unit. <br /> This will be determined at the time of the services. Recommend laundering be limited <br /> to 3 to 4 loads per day. Recommend to turn off your water when you are on vacation or <br /> not home for a period of time. <br /> Steven .
