The system consists of 2-1000 gallon septic tanks, <br /> 1-1000 gallon pumping chamber&a pressurized mound system with a 10'x 55'rock <br /> bed for a 4 bedroom home built in 1988. <br /> Soil boring#1 found mottled soil(redox features)at 1.5'into the original soil. Soil <br /> boring#3 found the original soil at elevation 92.3& bottom of the rock bed at elev. <br /> 92.9 leaving .6'of sand below the rock bed&a 2.1'separation from the bottom of the <br /> rock bed& redox features. Soil boring#2 found mottled soil at 1.7'into the original <br /> soil. Soil boring#4 found the original soil at elev.91.4&the bottom of the rock bed <br /> at elev.92.6 leaving 1.2'of sand below the rock bed &a 2.9'separation. The system <br /> meets the required 2'separation from the bottom of the rock bed & redox features& <br /> is classified as in compliance with Minnesota Chapter 7080 rules. <br /> The home has 5 bedrooms which requires a 10'x 63'rock bed. To add to the system, <br /> the existing rock bed will need to be removed&raised to elevation 93.8 to meet the <br /> 3'separation. The rock bed must be removed with 4"of sand &replaced with a <br /> backhoe(excavator)with limited travel on top of the mound (loam topsoil will need <br /> to be above the plastic limit). Then replace the rock bed,distribution pipes&sandy <br /> loam & loam cover. The rock bed will be added to at the east end of the mound. The <br /> topsoil cover removed from the mound may be used to re shape the side slope. <br /> Remove the rock&sand from the site. <br /> The existing tanks may be used upon completion of a Tank integrity report passing. <br /> If the tanks cannot be used,install 2-1250 gallon septic tanks&1-1250 gallon <br /> pumping chamber&the existing tanks will need to be abandoned,pumped&filled <br /> with soil &a Tank Abandonment report completed by a licensed contractor. The <br /> pump tank if used will need to have the hole sealed for a 2"diameter pipe. <br />
