The existing tanks will be <br /> abandoned, pumped & filled with soil & new tanks installed. A tank abandonment <br /> report must be completed by a licensed contractor. <br /> This site has very limited space for placing a new system due to steep slope, <br /> excavated & compacted soils. The only area available is west of the house. A <br /> standard system under Minnesota Chapter 7080 rules cannot be designed. The <br /> proposal is to install a Type IV, System under Minnesota Chapter 7080.0179 rules for <br /> a Type 1, 5 bedroom home with a 1.5' separation from the bottom of the bed & redox <br /> features. <br /> A Class 1, Multi-Flo Aerobic Wastewater Treatment system which is classified as <br /> standard under Minnesota Chapter 7080 rules will be used or a unit which has <br /> positive filtration and an alarm equivalent to a Multi-Flo Unit. The highly treated, <br /> filtered effluent produced by the Multi-Flo is over 95% free of the normal sewage <br /> contaminants that cause the progressive failure of conventional systems. The unit <br /> will be a 750 gal/day. A trash trap is installed in front of the Multi-Flo Unit. The unit <br /> requires to be serviced 2 times a year which will be done by Schirmers Wastewater <br /> Treatment Systems, Inc. A 2 year parts & service warranty comes with the cost of <br /> the unit. After that time, the homeowner is required to carry a service contract at a <br /> cost of$225.00 a year (2018 price). A report is sent to the homeowner, City , MPCA <br /> & Multi-Flo yearly. <br /> The soils on this site are a loam. The seasonally saturated soil, mottled soil (redox <br /> features) are located at 16" to 26". The proposal is for a pressurized seepage bed. <br /> The seepage bed will be over excavated to the loam soil elev. 99.9 to 101.0, then <br /> placed washed sand to elev. 104.6 leaving a 1.5' separation using SB#1 with mottled <br /> soil at 1.3', elev. 103.0. The north end of the bed will require approval for the to be <br /> 10' away from the West property line. <br /> Reviewed for Code <br /> Compliance City of Orono <br /> Date / ' .. <br /> Reviewer ..�. i i , ,��I <br />
