A) Uncover both tanks entirely and remove cover sections. <br />Have the tanks pumped out by a licensed septic tank pumper. <br />Have the pumper verify the proper elevations of inlet and <br />outlet pipes, verify the integrity of those pipes, and <br />repair or replace baffles within the tank as may be <br />necessary. <br />B) Uncover the first distribution box (and maybe additional <br />distribution boxes) in order to determine whether the flow <br />line is downhill from the tanks, and whether the drainfield <br />is saturated. <br />Your septic system was designed for a three to four bedroom <br />home based on soil testing done in 1977, which pre -dated the <br />current on -site system Code requirements. A review of the <br />original soil testing reveals that no indication of the existence <br />or non-existence of a seasonal water table was noted, which was <br />required after 1978. Such a seasonal water table was noted in <br />the property immediately to your west, and may exist on your <br />property. A seasonal water table near the surface has a <br />detrimental effect on trench -type drainfields, often limiting <br />their capacity. Because of that potential, it is not possible to <br />predict the actual capacity of your drainfield system nor is it <br />possible to predict with any degree of confidence whether that <br />system will continue to function for two weeks or another 20 <br />years. This is typical of all systems which were constructed <br />prior to 1978 without accountability for seasonal water tables. <br />Given the above information, if it is determined that the <br />abnor-mally high water level in the tanks is due to a restriction <br />Paz': 'he tanks that can be cleared, and not due to some other_ <br />f la- in the system, we would presume that the system wo,.,,1,3 <br />continue to function adequately as it apparently has in the past. <br />Please feel free to contact me or City Inspector Lyle Oman <br />if you have any further questions. Please call for an inspection <br />when the tanks are opened for pumpout. <br />Sincerely % <br />Michael P.
