Due to the periodically saturated <br /> soils, a pressurized mound system will need to be installed to treat the septic effluent. The bottom of the <br /> treatment area must be located at least 3' above the saturated soils. <br /> Due to limited space. The mound rock bed must be split into two 32 foot rock beds. <br /> The absorption area of the proposed systems do not overlap. <br /> This system is designed as a non- level pressurized trench system using gate valves to equalize the <br /> pressure. Use 7/32 inch perforations on the laterals. <br /> The soils at a depth of 12"have a percolation rate averaging 8.7 MPI. <br /> All neighboring wells are located�reater than 100' away from proposed treatment area. <br /> Two new !300 gallon septic tanks are to be installed.All tanks need to be insulated if there is less than two <br /> feet of cover over the top of the tanks. Clean outs must be installed on the end of the laterals for <br /> maintenance. <br /> A 1300 gallon Darwin precast pumping chamber must be installed to lift the effluent to the treatment area. <br /> The power supply and switches must be located outside the manhole and pumping chamber in a <br /> weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of <br /> a pump failure. The manifold and supply line must have back drainage to the pump chamber. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction <br /> With proper instaliation and maintenance,this system should have no problem in treating septic effluent <br /> effectively. Nothing other than bray water, (laundry, showers, etc.)Human water and toilet tissue should be <br /> disposed of inco the septic tanks. Garbage disposals are not recommended.Additives must not be used;they <br /> may cause harmful dama�e to your septic system. It is recommended that you pump tanks every two years. <br /> Sincere!y, CITY OF ORONO <br /> SF.PTIC P MIT PL R VIEW <br /> ,_ INSPF'CT R <br /> DATF. �- ERMITNO. 20��3z8 <br /> Joseph 1.
