The manifold and <br /> supply line must have back drainage to the pumping chamber. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction. <br /> The area around both sites must be fenced off by the contractor before any construction begins.This <br /> Design is not valid and the System will need to be relocated if failure to protect the areas proposed for <br /> On-Site Sewage Treatment occurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent <br /> effectively.Nothing other than gray water,(laundry,showers,etc.)Human water and toilet tissue should be <br /> disposed of into the septic tanks.Garbage disposals are not recommended.Additives must not be used;they <br /> may cause harmful damage to your septic system.It is recommended that you pump the tanks every two years <br /> Sincerely, <br /> Thkcf Sibc dlitoti <br /> Joseph J.Olson CIT OF ORONO <br /> SEPTIC PEWIT LAN REVIEW <br /> INSPECTOR <br /> DATE z z- ly PEEWIT NO. <br /> THIS SYSTEM IS DESIGNED FOR EJ APPROVED AS-1S.1.4 . > <br /> [] APPROVED K+F�H�K .i t 'NC AS NOTED <br /> ,.:,.BEDROOMS.
