A satisfactory <br /> percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> Only one test, shallow or deep, must pass for the parcel to be considered acceptable for standard septic systems. <br /> Discussion of Percolation Test Results <br /> The soils within the percolation test areas P1 B, P2, P3, and P4 have demonstrated <br /> satisfactory percolation rates for the use of standard septic systems utilizing leach lines <br /> and seepage pits in accordance with the requirements of the San Joaquin County <br /> Environmental Health Department. <br /> Discussion of Septic System Sizing <br /> Future septic system construction should follow the San Joaquin County On-Site <br /> Wastewater Disposal Standards (2016) where applicable. <br /> • <br /> LOGE 1704 Page 8 <br />
