Soil borings completed into the <br /> system showed no sign of hydraulic overtoading at the time. The upgrade period will <br /> need to be determined by the City of Orono. <br /> This site has very limited space for placing a new system. Soil probing indicates a <br /> mound system would be needed, but there is no area available to place a mound <br /> system due to fill soil, drainage, & steep slopes. A Standard system under Minnesota <br /> Chapter 7080 rules cannot be installed. The proposal is to install a Performance <br /> System under Minnesota Chapter 7080.0179 rutes for a Type 1, six bedroom home. <br /> The system will be a pressurized seepage bed with 1.5', 2.0' � 2.3' o#separation from <br /> the bottom of the rock and the seasonally saturated soil (redox features}. The <br /> maximum depth of the seepage bed will be elevation 98.0. A Class 1, Multi-Flo Aerobic <br /> Wastewater Treatment System which is classified as standard under Minnesota <br /> Chapter 7080 rules will be used or a unit that has positive filtration and an alarm <br /> equivalent to a Multi-Flo Unit. The highly treated, filtered efftuent produced by the <br /> Multi-Flo is over 95% free of the normal sewage contaminants that cause the <br /> progressive failure of conventional systems. The unit will be a 1000 gal/day. A trash <br /> trap is installed in front of the Multi-Flo. The unit �equires to be serviced 2 #imes a year <br /> which will be done by Schirmers Wastewater Treatment Systems, tnc. A 2 year service <br /> � parts warranty comes with the purchase of the unit. After that time, the homeowner is <br /> required to carry a Service Contraet at $150.00 a year (2003 price). A report is sent to <br /> the homeowner, city, MPCA 8� Multi-Flo yearly. <br /> To install the Performance System, approval will be needed from the local unit of <br /> Govemment. An aperating permit is required by the County. The permit will need to <br /> include monitoring of the seepage bed for hydraulic overloading. This could be done at <br /> 1 <br />
