7. The system makes use of 3 c.,:;,ncrete tanks. In the third or "pump" tank, which has a manhole to the ground surface, it is apparent that during saturated ground conditions there is some groundwater seepage into the tank through the manhole rings, as evidenced by water streaks inside the manhole. There is of course the possibility that other non -viewable joints and connections within all three tanks have similar seepage occuring. The extent of this seepage is unknown, hence the effect it has on the overall amount of water being pumped to the drainfield is also unknown. It is my understanding that your footing drain pump discharges separately from the household waste, hence this source of excess water is not r 4-:tor. 8. You will recall that thi: c system was installed prior to issuance of a permit. To ate on this, I seem to recall that the contractor called ;cuss what licensing and permits were needed some time prior to „he installation. Then, it was called to our attention that the system was in the ground already on 10-19-81, at which time I did an inspection and found nobody on the site, 2 tanks with stacks (but no manholes) in the ground and covered, the pump tank was in but no pump yet, the 4" line heading to the distribution box was in but no smaller pump line yet, and I found the distribution box with 4 drainfield lines still uncovered. At that time, with the major excavation work, piles of dirt in the drainfield area, there was no apparent problem with the drainfield system construction. Building Inspector Tom Jacobs talked with Mr. Printy about this on 10/22/81 and obtained the name of the contractor. Jacobs vi -4 ted the site on 10/23/81 az;d left an inspection slip to ha!o < septic contractor call the city. Permit No.6526 was €:, .y issued to Dalchow and Sons of Mayer, Minn. on 10/28/81, although our files indicate they never completed our licensing requirements, were never issued a license, and have not worked in Orono since that date. From what I can tell by the records, no followup inspection was made by Jacobs or myself to demand that the manhole risers be added for easy access to the first two tanks. Also, I do not know whether a high-water alarm ryas installed in the pump tank, although I do not recall seeing one. These two items would appear to be the only obvious discrepancies in what otherwise appeared to be a system meeting Orono's codes based on the soils and sitf- informatioi-, submitted. 9. On 6/5/84 I made an inspection of the septic system at the request of the realtor for mortgage purposes. At that time no sewage war surfacing, but I did note that some erosion was occuring over the east end of the drainfield and that continued erosion would likely expose the drainfield rock and cause
