Co. , MN <br /> i <br /> ' �2) <br /> � <br /> Due to the mound system bing located at the base of a slope, <br /> � recommend to install an Interceptor Drain. <br /> i <br /> An Interceptor Drain will need to be installed at a minimum depth of 4 ' <br /> below the up-s}.ope toe of the dike of the mound treatment area. Also <br /> a 10 ' horizontal distance between the dike of the mound and the <br /> Interceptor Drain. The Interceptor Drain must be backfilled with <br /> 3/4" dia. rock or clean sand or gravel . If sand or gravel is used, <br /> the tile must be wrapped with filter cloth. The rock must be <br /> backfilled within 12" of original grade & backfilled with 12" of <br /> original soil . <br /> Keep all heavy equipment off of the proposed treatment area before and <br /> after construction. The treatment area should be marked off before <br /> construction. This Design is not valid & the System will need to <br /> be relocated if failure to protect the areas proposed for On-Site <br /> Sewage Treatment occurs. <br /> With proper installation and maintenance, this system should have no <br /> problem in treating septic effluent effectively. <br /> Nothing other than gray water, (laundry, showers, etc. ) human <br /> waste & toilet tissue should be disposed of into the septic tanks. <br /> Garbage disposals are not recommended. Smaller amounts of laundry <br /> soaps, dish soaps, cleaning agents , etc. are better for the system. <br /> Antibacterial soaps & chlorine agents may kill the bacteria needed <br /> to treat septic effluent properly. Additives are not recommended, <br /> they may cause harmful damaqe to your system. Recommend to pump <br /> & clean your tanks by a certified pumper every year if you have <br /> 1 tank & every 2 years if you have 2 tanks to insure proper <br /> maintenance. <br /> � ry � <br /> even B.
