Mottling in the soil profile indicates that the <br />winter water table is to high to consider this site for <br />any system other than the sand filter system as a "full <br />code" repair. You are probably aware, the sand filter <br />system is a rather expensive system. As a repair, you <br />might want to consider something less, such as a low <br />pressure distribution installation in lieu of the sand <br />filter. Keep in mind however, that anything other than <br />the sand filter is substandard to current rules pertain- <br />ing to subsurface sewage disposal, and as such there is <br />some risk that another repair might not perform at all <br />times without some problem. <br /> <br />I suggest that you consider the low pressure system as a <br />repair for two reasons. The first is that the low pres- <br />sure system distributes the effluent evenly over the <br />entire drainfield through smaller pressurized distribu- <br />tion laterals. This prevents saturated flow from one <br />small area of a single drainline into the shallow region- <br />al water table. The second reason is that the pressure <br />distribution utilizes the same kind of effluent pump that <br />a sand filter system employs so that pumping unit will <br />already be in place i~ the alternate system should prove <br />inadequate. <br /> <br />Senator Building · 220 High Street NE Salem, Oregon 97301-3670 <br /> <br /> <br />
