As being a longtime licensed septic installer in the Town of North Andover,the Board of Health requires that a building sewer pipe from the house be completely straight without any bends. Therefore,when we uncovered the building sewer pipe,we found that it came out at an angle not as planned. We had to make a field change by turning the tank to accept the building sewer pipe to an inlet on the tank. While we were installing this,we were obtaining severe ground water and collapsing soil due to the high water table.It became so bad that we were nervous about undermining the existing foundation and stairs at the back of the house. Michelle Grant,the N.Andover Health Inspector,was present during this situation and witnessed this unmanageable situation.After taking ties to the property line,the foundation and existing wetland flags placed in the ground, we were all within setbacks set by the code and plan. It has come to my attention after the septic as-built was completed;Merrimac Engineering explained to me that the tank was inside the 50 foot buffer zone. I explained to them that we measured from the flags in the ground and were out of the buffer zone. Ile then explained to me that there was a new delineation line for the wetlands that never got staked out. As you can see,this was a very simple mistake on my part and I am looking for help to solve this matter any way away from moving the tank due to the unstable soil we ran into setting the tank originally. I am looking for the committee to understand this simple mistake and hope this can be taken care of by a simple variance on the plan.1 holy appreciate your attention to this matter.
