At the time of the inspection, the system was not <br /> surface discharging but the area was very moist. If the system surface discharges, the <br /> system is classified as an imminent health hazard and must be repaired or <br /> disconnected within 10 months. <br /> This site has very limited space for placing a new system due to low areas, lake <br /> setback & excavated & filled soil. A Standard system under Minnesota Chapter 7080 <br /> rules cannot be installed. The proposal is to install a Performance System under <br /> Minnesota Chapter 7080.0179 rules for a Type 1, five bedroom home. The system will <br /> be a pressurized trench system with 14", 18" & 22" of separation from the bottom of the <br /> rock and the seasonally saturated soil (redox features). 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 effluent 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 750 gallday. A trash <br /> trap is installed in front of the Multi-Flo. The unit requires to be serviced 2 times a year <br /> which will be done by Schirmers Wastewater 1�reatment Systems, Inc. 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 Contract at $150.00 a year (2003 price). A report is sent to <br /> the homeowner, city, MPCA & Multi-Flo yearly. <br /> To install the Performance System, approval will be needed from the local unit of <br /> Government. An operating permit is required by the County. The permit wifl need to <br /> include monitoring of the seepage bed for hydraulic overloading. This could be done at <br /> the same time the Multi-Flo is serviced. Lab samples will be needed to test for fecal <br /> coliforms, recommend 1 time a year at a cost of$75.00 to $100.00 per test.
