The periodically saturated soils were located at 12-18 inches(mottled soil).Due to the periodically saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom of the treatment area must be located at least 3'above the saturated soils. All neighboring wells are greater than 100'from proposed treatment areas. ,_. � _ Ctx�:��:e�. s:��'Y The soils at a depth of 12"have a percolation rate averaging 13 MPI. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Ciean outs must be installed on the end of the laterals for maintenance. Use 7/32 inch perforations on the laterals. A small drainage swale should be created in the drainage way to make the surface water drain away from the septic sites better. A 1300 gallo�lift station must 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 light and sound devices;this is in case of a pump failure. Nothing other than grav water,(laundrv,showers,etc.)Human water and toilet tissue should be disposed of ioto the septic tanks.Garba¢e disposals are not recommended.Additives must not be used; they may cause harmful dama¢e to vour septic svstem. It is recommended that vou puma the tank everv vear for 1 septic tank,everv two vears for two septic tanks.
