The system best suitable for this area �vill be 418 If. of 10" Gravelless trench in�talle� <br /> no deeper than 24" below the existin�� ground level. �t�he seasonal high water table was found at a depth <br /> of 5.0 feet in the septic area. rwo I 300 gallon septic tanks �vill be adequate for a system of this �i�e. <br /> The site in which this system is proposed has an average existing ground slope of 10%. Percolation <br /> rates for this particular site were found to be between 10-16 MPI. <br /> An alternate septic system has been designed to show 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. The seasonal <br /> water table was also found at a depth of 60 inches, this site would also require 418 If. of I 0" Gravelless <br /> trench. This system will not need to be constructed unless the primary system fails. <br /> Certain precautions will need to be made to protect the areas in which the above referenced septic <br /> systems are proposed. Botl� primary and alternate septic areas have been or will be staked off. It is <br /> recommended that safety fence be placed around both of the sites for protection during construction of <br /> this project. It is critical that the soil is not disturbed before, during, and after construction of the <br /> system. <br /> These system should treat the septic effluent effectively if the systems are installed properly and are <br /> maintained properly. It is recommenced that the septic tanks be pumped once every two years. T�his <br /> will reduce the chance of solids reaching the system. It is also recommended not to use excessive <br /> amounts of chlorine, soaps, and chlorine products which can kill bacteria in the septic tanks. "l�his <br /> bacteria is needed to treat the septic effluent <br /> Designiny the Future ToAay. since 1912 <br />
