The seasonally saturated soils were located at 18"-24"(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 existing house is going to be removed.The existing septic tanks could not be found but must be abandoned. Due to limited space that is undisturbed.The future systems upslope dike must overlap the primary systems downslope dike.The absorption areas do not overlap.The future septic site must be fenced off when the primary site is being installed.When the septic system is built all materials must be placed from the southwest side of the system. The soils at a depth of 12"have a percolation rate averaging 8 MPI. ORONO COPY All neighboring wells are located greater than 100'away from proposed treatment area- All reaAll new tanks need to be insulated if less than two feet deep.Clean outs must be installed on the end of the laterals for maintenance. A 1250 gallon 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 light and sound devices;this is in case of a pump failure. Keep all heavy equipment off of the proposed treatment areas before,during and after construction. The area around both sites must be fenced off by the contractor before any construction begins.This Design is not valid and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. Nothing other than Bray water.(laundry,showers,etc.)Human water and toilet tissue should be disposed of into the septic 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 tank every year for 1 tank,every two years for two tanks.
