Septic �:ystem Jesign <br /> Additional Information <br /> Property <br /> Owner Kevin Scherer-2160 6'h Ave N Orono, MN 55356 <br /> Description of Waste Water Treatment System <br /> This site is an existing home built in 1966. The home has a failed septic system due to soil <br /> separation and tank integrity. The existing tanks will need to be dug up, pumped and <br /> abandoned 2-1000 gallon septic tanks will need to be installed along with a 1000 gallon pump <br /> tank to lift effluent to the proposed mound The mound is proposed south of the home in the <br /> wooded portion of the lot. A few trees are in the way and will need to be cut down. The <br /> proposed mound will have a 2 foot sand lift with a 10x37.5' rockbed. From the pump tank <br /> effluent will be lifted 170 ft to the mound. A portion of the supply line will be installed under the <br /> asphalt driveway. This section of the supply line MUST be insulated. (insulated pipe or foam <br /> sheeted insulation) Installer to ensure supply line has good fall from mound back to tank <br /> especially under driveway. A portion of the asphalt driveway will have to be removed in order to <br /> install supply line. A flow measurement device must be installed on the pump tank. <br /> This new on-site sewage treatment system is designed for a 3 bedroom home, Type 1 system in <br /> accordance with the MPCA Chapter 7080 and local ordinances. <br /> The soils on this site are loamy. The periodically saturated soils were located after going to a <br /> depth of 14 inches. This will lead 12 inches of usable soil underneath the mound with a 2 foot <br /> sand lift. Therefore providing a 36 inch separation for the treatment of effluent above the <br /> periodically saturated soils. <br /> 2-1000 gallon tank will need to be installed along with a 1000 gallon pump tank to lift the <br /> sewage to the treatment area. The power supply and switches must be located outside the <br /> manhole and pumping chamber in a weather proof enclosure. A warning device must also be <br /> installed with audio/visual alerts. The supply line must have drain back to the pumping chamber. <br /> From the pump tank sewage will be pumped approximately 170 feet to the mound. There will be <br /> 3- 2" pipes each 3 feet apart inside the 10" by 37 5' rockbed. The mound will have a total <br /> footprint of 54' by 78' with 10 percent slope underneath it. <br /> All tank manholes should be brought to grade upon completion of tank installation, inspection <br /> ports for the distribution boxes should also be at grade upon completion <br /> Keep all vehicles and construction equipment off septic area. Rutting and/or compacting the <br /> soil wi�l change the percolation rates and may lead to system failure. <br /> Homeowner to verify all property lines. <br /> Elevations are referenced to Bench Mark on the asphalt next to sidewalk of home. <br /> _ __ <br /> ---_---- -___ --- - <br /> Ende 5eptic Service, LLC,24910 Territorial Road �ph 763-428-4489 or `_ i__ - , 1 <br />
