Once the house size,location and septic primary and future sites are chosen this design can be completed. The seasonally saturated soils were located at 12"-16"(mottled soil).Due to seasonally saturated soils,a pressurized Mound System will need to be installed to treat septic effluent.The bottom of the treatment area must be located at least 3'above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 12.6MP1. Due to limited,space on the lot.Site A and Site B are combined.The absorption areas do not overlap. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A filter needs to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. A pumping chamber will need to be installed to lift the effluent to the treatment area.The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A warning device must be installed with a light and sound device;this is in case of a pump failure. Use 7/32 inch perforations on the laterals Keep all heavy equipment off of the proposed treatment areas before and after construction.The C treatment area must be fenced off before construction begins.This Design is not valid&the System � will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment .�, systems occurs. O n Nothing other than gray water,(laundry,showers etc.)Human water and toilet tissue should be �rd� disposed of into the seotic tanks.Garbage disposals are not recommended Additives must not be used:they may cause harmful damage to your septic system It is recommended that you pump the tanks every two years.
