Page 8 - 0120 86-74 450 gallons, based on a three bedroom. Type 1 residence, the required total treatment area is about 570 square feet. We suggest scarifying (tilling) the surface sod and then bringing in about 2' of sandy loam, loam or sand with about 10% fines. The fill material should only receive light compaction, sufficient to achieve a density equivalent to long-term settlement under its own weight. After the fill placement, trenches should be dug to a depth of about 2'-21', and these should be about 3' in width. About 9" of filter rock should be placed below the perforated laterals. For 3' wide trenches, the total trench length should be about 190'. Four -48' long trenches spaced about 6' apart (71' on center) would require filling an area of about 70' x 50' for the primary system. About 26 cubic yards of filter rock would be needed. Where any trench extends to within 8' of a tree or potentially large tree, additional filter rock should be placed. We strongly discourage the use of a garbage dis)osal. Traffic of all types, except for occasional mowing of the grass with light equipment, must be restricted throughout the year. The system should be monitored and the septic tank should be pumped, probably eery two years or so, to promote longivity of the soil treatment system. The existing sprinkler system must be removed from the new drainfield area. FIELD EXPLORATION PROCEDURLS The borings were made on April 17, 1985. The borings were put down at the locations suggested by you or disciissed with you as shown on the attached Soll LXIPLORENtlon
