Bob Voronyak <br />November 19, 1992 <br />The quantity of effluent delivered each pump cycle should be <br />at least 110 gallons, but no more than 130 gallons per <br />cycle. <br />The amount of effluent pumped per cycle depends on the <br />surface area of the pumping tank and the setting of the pump <br />start and stop. A relatively large pumping tank surface <br />area is needed with a small pump out depth. <br />- <br />There are several pumping situations that can be uspdwith <br />this on —site sewage treatment system. These situations <br />should should be in concurrence with the County Ordinance and the <br />contractor installing the system. <br />Inspection Pipe <br />---------------- <br />A vertical inspection pipe at least 1 1/2 inches in diameter <br />to the bottom shall be installed in the rock layer of the <br />mound. The inspection pipe shall be located at an end <br />opposite from where the sewage tank effluent enters the rock <br />layer, The inspection pipe shall have 3/8 inch, or larger, <br />perforations spaced vertically no more than six inches <br />apart. At least two perforations shall be located in the <br />rock layer. The inspection pipe shall extend to the bottom <br />of the rock layer with an elbow beneath it and shall be <br />capped flush with or above the finished grade. <br />
