066 3 In general, the Georgeville and Herndon soils are considered to be provisionally suitable according to the rules and regulations promulgated by the Division of Health Service. The Lignum-like soils encountered on the site are considered to be unsuitable for design and development of subsurface systems and only provisionally suitable for design and development of spray irrigation or surface application systems. The limitations of the Georgeville and Herndon-like soils can be overcome through conservative hydraulic loadings. The application between .2 and .25 gallons/ft2/day with pressure distribution or .3 gallons/ft2/day with conventional distribution is an acceptable hydraulic loading. The application rate onto the Lignum-like soil is determined through a water balance calculation. The water balance calculation is attached and will be discussed in the following section on recommendations. The water balance calculation does indicate, however, that approximately 20 inches of water can be applied over the site. Soils are a limitation to optimum development of this property. Lot sizes must be quite large to accommodate the development potential of this property. The installation of both subsurface wastewater treatment systems and surface treatment systems are necessary to allow for optimum development of this property. The design limitations can be overcome through careful placement, careful design, and careful operation of the selected wastewater treatment options. Recommendations There are two distinct options which are available for handling the wastewater generated at the Wolfe site. One is to utilize a slow rate spray irrigation system to handle a portion of the waste flow and a community subsurface wastewater treatment and disposal system to handle the wastewater from the remaining homes.
