Due to mottled soils at a depth of 24" in the primary site, the primary will need to be a <br /> mound system with 12"of sand under the rockbed at the upslope side. The site in which this system is <br /> proposed has a average existing ground slope of 5%, and percolation rates ranging from 19-30 MP1. The <br /> rock bed size wi(I be 10 feet wide and 63 feet long with the overall dimensions of the primary mound <br /> bci��g 84.0 feet long and 39S fect wide. <br /> An alternate septic system has been designed to sho��� that there is enough undisturbed area on the lot to <br /> support another septic system. This system was also designed for a 5 bedroom home. Mottled soils <br /> were found at a depth of 20 inches this would also require a mound system. The average slope of the <br /> area is 10% with percolation rates between 12 and 37 MI'1. Thc rock bed size will also be ]0 feet wide <br /> and 63 feet lon�. This mound will not need to be constructed unless the primary mound fails. <br /> Certain precautions will need to be made to protect the areas in which the above referenced 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 system should treat the septic effluent effectively if the system is installed properly and is <br /> maintained properly. It is recommenced that the septic tanks be pumped once every two years. This <br /> will reduce the chance of solids reaching the mound system. It is also recommended not to use <br /> excessive amounts of chlorine, soaps, and clllorine products which can kill bacteria in the septic tanks. <br /> This bacteria is needed to treat the septic efflueni. <br /> If you have any questions in regards to this design, t will be happy to answer them. 1 can be reachcd at <br /> (612) 682-2587. <br /> Sincercl�, <br /> WES I'W(�OU PROI�LSSIONAI_ SERVICLS, INC. <br /> �!�.� �� / % <br /> � /� <br /> 13crnic �lilicr , <br /> Scptic Site Dcsigncr <br /> MPCA Lic.
