The periodically saturated soils were located at 20-28 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. T`he existing septic system dces not conform to the state code chapter 7080 All neighboring wells are greater than 100' from proposed treatment areas. The soils at a depth of 12"have a percolation rate averaging 2.7 MPI. The existing septic tanks must be abandoned and two new 1300 gallon septic tanks need to be installed. All new tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Clean outs must be installed on the end of the laterals for maintenance. A new 1300 gallon lift station must be installed to lift the eftluent 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. Not6ing other than grav water (laundrv showers etc 1 Human water and toilet tissue should be d�saosed of mto the seotic tanks.Garbage disposals are not recommended Additives must not be used:thev mav cause harmful damage to vour se�tic svstem It is recommended that vou auma the tank everv two vears for two se�tic tanks.
