The percolation tests completed 12" into the original soil had a perc rate of 10.4mpi <br /> which also did not indicate compaction. The proposal would be to remove the fill soil <br /> with a backhoe if the site would ever need to be used. A complete design would be <br /> needed at that time. <br /> If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers must <br /> be insulated to a value of R10. <br /> Cleanouts for each later must be installed & be accessible from finish grade in an <br /> irrigation box with a ball valve. <br /> Keep all heavy equipment off of the proposed treatment area before and after <br /> construction. The treatment area should be marked off before construction. This <br /> Design is not valid & the system will need to be relocated if failure to protect the areas <br /> proposed for On-Site Sewage Treatment occurs. <br /> MANAGEMENT PLANS: <br /> The tanks need to be pumped every 2 years. Check with your pumper to set up a <br /> schedule. <br /> System inspected for wet areas by owner & or Inspector as determined by the local unit <br /> of government. <br /> Any other requirements as determined by the local unit of government <br /> With proper installation and maintenance, this system should have no problem in <br /> treating septic effluent effectively. <br /> Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. <br /> should be disposed of into the septic tanks. Recommend Iron filters be diverted out of <br /> the system. Recommend to divert the water softner also if the iron filter is diverted. <br /> Garbage disposals are not recommended, due to adding more solids & fine solids <br /> passing through to the system. Excessive amounts of soaps, antibacterial soaps, <br /> cleaning agents, shower cleaners used every shower & chlorine agents may kill the <br /> bacteria needed to treat septic effluent. Additives are not recommended. Recommend <br /> laundering be limited to 3 to 4 loads per day. <br /> Steven B. Schirmers <br /> 2 <br />
