Soil conditions are not acceptable to <br />consider the site for a standard system, but the soil is <br />marginally suitable to construct an alternative sand <br />filter plus a full capping fill system repair. As the <br />conditions are marginal, the drainfields must be con- <br />structed only within the immediate area of the soil test <br />pits. <br /> <br />The appropriate sand filter system for your three bedroom <br />residence will include a 1000 gallon dosing septic tank <br />and 150 lineal feet of drainfield. The drainfield trench- <br />es must be limited to 12 inches deep (minimum/maximum) <br />into the natural undisturbed topsoil. Sixteen inches of <br />similar capping fill material will be necessary to cover <br />the shallow drainline trenches. Normally the installation <br />of the capping fill material is limited to the dry summer <br />season. Since the repair is necessary at this time to <br />correct and existing health hazard, the drainline trench- <br />es may need to be constructed to the point of installing <br />the fill and secured with a protective filter fabric <br />until the fill material can be installed at a later date. <br /> <br />The plans for the sand filter repair system should be <br />submitted for a plan review at this time. When the plans <br />are approved the permit can be issued to a licensed <br />septic system installer of your choice. <br /> <br /> Refer to the enclosed setback list which outlines the <br /> minimum separation distances between components of the <br /> septic system and other features.
