Due to mottled soils at a depth of 24" in the primary site, the primary system will need <br /> to be a mound system with 12" of sand under the rockbed at the upslope side. The site in which this <br /> system is proposed has a average existing ground slope of 6%, and percolation rates ranging from 4-14 <br /> MP(. �I he rock bed size will be 10 feet w ide and 63 feet long with the overall dimensions of the primary <br /> mound being 93 feet long and 39 feet wide. The mound system will require two 1300 gallon septic <br /> tanks plus a 1300 gallon pump tank. <br /> An alternate septic system has been shown on the plan to show that there is enough undisturbed area on <br /> the lot to support another septic system. This system wi(I also need to be a mound system. Mottled <br /> soils were found at a depth of 26"and the average slope of the area is 6%. This system will not need to <br /> be constructed unless the primary mound fails. <br /> Certain precautions will need to be made to protect the areas in which the above refereneed septic <br /> systems are proposed. Both primary and alternate septic areas have been or will be staked off. It is <br /> critical that the soil is not disturbed before, during, and after construction of the system. <br /> These systems should treat the septic eftluent effectively if the systems are installed properly and are <br /> maintained properly. It is recommenced that the septic tanks be pumped every two years. This will <br /> reduce the chance of solids reachin�, the mound system. It is also recommended not to use exeessive <br /> amounts of chlorine, soaps, and chlorine products which can kill bacteria in the septic tanks. This <br /> bacteria is needed to treat the septic effluent. <br /> If you have any questions in regards to this design, 1 will be happy to answer them.
