Carolyn Kozloski 405 Old Crystal Bay Rd. So. Orono, Henn. Co., MN This site has an existing on-site sewage treatment system which is surface discharging septic effluent. The system is classified as an imminent health hazard and must be repaired or disconnected within 10 months. This site has very limited space for placing a new system. Soil probing indicates a mound system would be needed, but there is no area available to place a mound system. A Standard system under Minnesota Chapter 7080 rules cannot be installed. The proposal is to install a Performance System under Minnesota Chapter 7080.0179 rules for a Type 1, three bedroom home. The system will be a pressurized seepage bed with 12" to 18"of separation from the bottom of the rock and the seasonally saturated soil (redox features). A Class 1, Multi-Flo Aerobic Wastewater Treatment System which is classified as standard under Minnesota Chapter 7080 rules will be used. The highly treated, filtered effluent produced by the Multi-Flo is over 95% free of the normal sewage contaminants that cause the progressive failure of conventional systems. The unit will be a 500 gal/day. A trash trap is installed in front of the Multi- Flo. The unit requires to be serviced 2 times a year which will be done by Schirmers Wastewater Treatment Systems, Inc. A 2 year service & parts warranty comes with the purchase of the unit. After that time, the homeowner is required to carry a Service Contract at $125.00 a year (2002 price). A report is sent to the homeowner, city, MPCA & Multi-Flo yearly. Approval will be needed to be 10' from the south & east property lines with the system and 10' from the south property line and 15' away from the house with the tanks. To install the Performance System, approval will be needed from the local unit of Government. An operating permit is required by the County. The permit will need to 1 M t include monitoring of the seepage be for hydraulic overloading. This could be done at the same time the Multi-Flo is service Lab samples will be needed to test for fecal coliforms, recommend 1 time a year a a cost of$75.00 to 100.00 per test. The1st tank will be a 1500 gallon tras trap dosing chamber reversed using the 500 gallons as a trash trap and the 1000 allons as a dosing chamber (pump #1) which will dose 9.3 gallons every 30 minutes to he Multi-Flo Unit. The effluent will flow gravity from the Multi-Flo to the 1500 gallon umping chamber (pump#2)which will pressurize the seepage bed. The power supply nd switches must be located outside the manhole and pumping chamber in a Bather proof enclosure. A warning device must be installed with a light and sound de ice, this is in case of a pump failure. The mitigation plan is to move the well and add additional drainfield if hydraulic overloading would occur and also bysing the 1500 gallon pumping chamber allows the effluent to be stored during peak .. e and pumped to the system during low water use periods. A timer could also be added to reduce the amount of effluent pumped to the system. A water meter will need to be installed to monitor daily water use. The soils at a depth of 12" have a per olation rate of 7.5 mpi. All neighboring wells are located great r than 100' away from the proposed treatment area. Keep all heavy equipment off of the pr posed treatment area before and after construction. The treatment area shou d be marked off before construction. This Design is not valid &the system will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. 2 Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic t nks. Iron filters must be diverted out of the system. Recommend to divert the wat r softner also. Garbage disposals are not recommended, due to adding more soli s &fine solids passing through to the system. Excessive amounts of soaps, anti-bact rial soaps, cleaning agents, shower cleaners , used every shower&chlorine agents y kill the bacteria needed to treat septic effluent. Additives are not recommend The trash trap, Multi-Flo and pumping chamber will need to be pumped out w en the setable solids reach 50% in the unit. This will be determined at the time of th services.
