Blunder of the week
I have been working on a sewer line project. Part of the project is to get inverts on all the manholes. Last week I asked the town to uncover the last of the manholes. My son and I rushed out the next morning and took the inverts before the arrival of a storm. There was this one manhole that was buried about 3 feet. We had a hard time pulling the manhole cover out of the hole and even a harder time putting it back in place due to debris falling back on the rim. Yesterday I was calculating invert elevations when I noticed one manhole that the invert in was about a foot lower the the invert out.
Guess which manhole it was?
This morning we went out to the site to shoot utility locates and decided to check the inverts on that manhole. The town had covered it back up, there was a foot of new snow, it had rained the night before(weird for January) When we finally got the rod readings, I had transposed a 5.65 to a 6.56 and we were covered in mud.I am always joking, saying a bad day in the field is better the a good day in the office.
