(4-bedroom home) <br /> Amount of sand under the rock bed— 1 ft. <br /> Size of septic tanks 2-1000 gallon sealed tanks <br /> Size of pump tank 1-1000 gallon sealed tank <br /> Two soil borings were done along the same land contour that the mound system was <br /> installed on to determine the type of soil profile that existed, where the mound was placed <br /> on. <br /> Soil boring# 1 indicated mottled soil at 24 inches ( 2.0 ft. ) <br /> Soil boring# 2 indicated mottled soil at 27 inches (2.2 ft.) See Soil boring logs. <br /> Mottled soil is consider the high seasonal saturation level that exist during the wet <br /> seasons (fall and spring) <br /> With,,the 1 ft. of sand under the rock and mottled soil level at 2.0 ft. the require 3 foot <br /> separation from the bottom of the rock bed to mottled soil level is satisfied. <br /> However when the tanks (2-1000 gallon septic tanks & 1-1000 gallon pump tank) <br /> were inspected it was discover that they all were full'into the risers which <br /> indicates that they are over there capacity. Therefore they require immediate pumping <br /> before they backup into the house or bleed out onto the surface. <br /> With the above situation this system is consider to be a potential health threat and must <br /> be corrected immediately . by pumping these tanks ( all three tanks ). <br /> Only after the tanks are pump the tanks can be accurate inspected as to the condition of <br /> the baffles. <br /> Also when the pump was plugged in, the pump did not work and there was not any <br /> electric at the pump outlet. This could mean that the pump by not working causes the <br /> circuit breakage to go to the off position, or there is a problem with the electricity to the <br /> pump outlet. <br /> Therefore this system is consider to be A HEALTH THREAT AND MUST BE <br /> CORRECTED IMMEDIAT LY. <br /> ettjt ec,e) . ill Pc iq /4 <br />
