SAND FILTER systems are installed in soils where a layer <br /> that limits the effective soil depth, or a water table is <br /> present in the soil profile at a depth much shallower than <br /> allowed for a standard system. The sand filter unit <br /> pre-treats the septic tank effluent before it is discharged <br /> into the ground. The drainfield following the sand filter <br /> is installed at a very shallow depth and generally lncludes <br /> a capping fill drainfield. See the attached Sand Filter <br /> System Requirements for Plans", Two sets of plans for the <br /> system must be submitted at the time of application for the <br /> installation permit. <br /> <br /> <br />
