ORONO <br /> COPY <br /> The existing house is going to be removed.A new house will be built. <br /> The absorption areas do not overlap. <br /> The existing septic tank must be abandoned.Two new 1300 gallon and a 1300 gallon septic tank must be installed. <br /> 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 <br /> installed on the end of the laterals for maintenance. <br /> Use 7/32 inch perforations on the laterals. <br /> All neighboring wells are located greater than 50'away from proposed treatment area. <br /> A1300 gallon pumping chamber will need to be installed to lift the effluent to the treatment area.The power supply and <br /> switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A warning device <br /> must be installed with light and sound devices;this is in case of a pump failure.The manifold and supply line must <br /> have back drainage to the pumping chamber.Be sure the rock and sand fill materials are clean. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction.The area <br /> around both sites must be fenced off by the contractor before any construction begins.This Design is not valid <br /> and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment <br /> occurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. <br /> Nothing other than gray water,(laundry,showers,etc.)Human water and toilet tissue should be disposed of into the <br /> septic tanks.Garbage disposals are not recommended.Additives must not be used;they may cause harmful damage to <br /> your septic system.It is recommended that you pump the tank every year for 1 tank,every two years for two tanks. <br /> Sincerely, <br /> CITY OF ORONO <br /> SF,PTIC P,'MI ► P 'A' ji. ,V1:44110 <br /> ,/__.------------- <br /> INSPECTORv► <br /> Joseph J.Olson DATE ' ,1 1 ERMIT NO. <br /> APPROVED AS st.rl'vIrrut) <br /> El API'ROVID„'VIII CORRECTIONS AS NOT1l) <br /> iimir <br /> 111 SYSTEM IS DESIGNED FOR <br /> F-1 No <br /> Ni APc cry E.D_c c,c: c r Rest rk,ha <br /> SS ORONO COPY TI , "'"' 1 arc n ion All \\urk,hall be done <br /> 4.............BEDROOMS.
