The soils at the site consist of ��'"`J . Standing water was not encountered in any of the soil borings, but mottling associated with seasonal saturation (wet soils) was found as shallow as 2�inches below grade surface and as deep as ��inches below grade surface. This indicates that a standard trench system is not suitable for the site. The perc test results ( 3o•r A�� ) indicate that the soils are suitable for treatment using a mound system. The home is an existin� � bedroom home. A standard mound system with )!P inches of clean washed sand below the distribution rock _ should be suitable as a new system for the site. We recommend a flow of ��'O gallons per day for use in design, and aZZ�o gallon septic tank and/Z.fogallon pumping tank. THIS SYSTEM MUST BE INSTALLED BY A LICENSED INSTALLER IN ACCORDANCE WITH CHAPTER 7080.
