[7] Continued. <br /> Due to the uniqueness of this proposed project in which sewage will <br /> be primarily accepted on Sundays, seepage pits and a calculated <br /> 13 , 000 square foot leach area should be required. The seepage pits <br /> should have a diameter of 48 inches I. D. and be installed to a <br /> maximum depth of 25 feet. These pits will be located within the <br /> areas and depths of the sand strata that will promote adequate <br /> percolation of effluent. <br /> As noted above, the water table is located approximately 60 feet <br /> below grade. Therefore, the groundwater level in this area is <br /> definitely below the ten foot minimum distance between the bottom <br /> of the seepage pits (approximately 25 feet below grade) and the <br /> highest anticipated depth to groundwater. Although the sand <br /> located at the 25 foot depth in the exploratory boring was moist, <br /> there was no indication of the water level appearing at this depth <br /> at any time in the past. Groundwater indications would have <br /> included mottling or possibly a rust color to the sand and a high <br /> degree of dampness. <br /> Based upon this information concerning the placement of the <br /> proposed seepage pits within the percable soil profile, and the <br /> highest anticipated depth to groundwater, there should not be any <br /> adverse impact to the quality of the local area groundwater or <br /> surface water from the proposed septic systems. <br /> A document search conducted at the San Joaquin County Department <br /> of Environmental Health of past applications for septic system <br /> repair revealed the following information: Within a one mile <br /> radius, there were 17 applications for septic system repair or <br /> additions. Eight applications were for installation of additional <br /> leach lines for increased drainage, and nine applications were for <br /> additional leach lines and seepage pits. These failures are most <br /> likely due to the extensive clay layers that are found at the usual <br /> leach line placement depths. It also illustrates that either <br /> additional drainage or seepage pits are necessary in this area for <br /> the adequate disposal of sewage effluent. <br /> 6 <br /> O (')uality (,.ontrol Inspection <br />
