All furrows shall be thrown uphill and there <br /> shall be no dead furrow under the mound. The soil <br /> shall be plowed only when the moisture content of a <br /> fragment 8 inches below the surface is below the plastic <br /> limit. <br /> c) In softs having percolation rates faster than 15 minutes <br /> per inch (sandy lo-ms) in the top 8 inch depth, disking <br /> may be used for surface preparation as a substitute for <br /> plowing. <br /> d) Mound construction shall proceed immediately after <br /> surface preparation is 6ompleted. <br /> e) The original soil must not be excavated or moved more <br /> than 1 foot from its original location during soil surface <br /> preparation. <br /> <br /> A m~uim~?m of 12 inches of soft defined as sand shall be <br /> placed where the filter material is to be located. A crawler <br /> tractor veith a blade sl~]] be used to move the sand into place. <br /> At least 6 inches of sand shall be kept under the tracks to <br /> m~njm~ze compaction of the plowed layer. The sand layer <br /> upon which the Falter material is placed shall be level. <br /> <br /> A depth of at least 9 inches of filter material shall be placed <br /> over the bed area below the distribution pipe. <br /> <br /> Distribution of effluent over the filter material shall be 1.25 <br /> inch diameter perforated pipe under pressure from a <br /> manifold. <br /> <br />The quantity of effluent per pnmp dose shall be at least 150 <br />gallons per bedroom for dwellings. For other <br />establishments, the dose shall be at least 25% of the <br />estimated or measured daily sewage flow. <br /> <br />At least 2 inches of filter material shall be placed over the <br />distribution pipes. The top of the filter material shall be level <br />in all directions. <br /> <br />Straw or marsh hay to an uncompacted depth 4 inches shall <br />be placed over the filter material. <br /> <br />Construction vehicles shall not be allowed on the filter <br />material muff] bactffill is placed. <br /> <br />Printed 1~28/90 <br /> <br />Page 257 <br /> <br /> <br />
