The system is also classified as an imminent health hazard due <br /> to the tank collapsing & causing back up into the home. The system must be repaired <br /> or disconnected within 10 months or as determined by the City of Orono. <br /> This site has an area available to install a Standard Mound System under Minnesota <br /> Chapter 7080 rules but would require the well to be moved. When this well was put in <br /> they had to go several hundred feet which was very expensive. <br /> There is an area available in the northeast corner of the property which has fill & <br /> compacted soil. The proposal is to install a system designed for a Type 1, four <br /> bedroom home, in accordance with the Minnesota Pollution Contral Agency Chapter <br /> 7080.0178 and local ordinances as an Other System. The fill & compacted clay soil will <br /> be removed to elev. 93.4. The bottom of the excavation will need to be roughened up a <br /> minimum of 8" &then backfill with clean washed sand to elev. 98.9 & place an elevated <br /> pressurized seepage bed. A monitoring plan is required with a minimum of monitoring <br /> for hydraulic overloading & monitoring the daily water use. This will need to be <br /> determined by the City of Orono. A water meter will need to be installed. <br /> To assure help assure long term survival of the system, recommend to install a Multi- <br /> Flo Wastewa#er Treatment System. The highly treated, filtered efFluent produced by <br /> the 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 600 gal/day. A trash <br /> trap is installed in front of the Multi-Flo. The unit requires to be serviced 2 times a year <br /> �$�1��'��NEfl�t <br /> � '�BEDROOMS.
