Our septic tank required attention this past week*, which involved Younger Son digging up part of my flower bed to find the pump-out access hatch. Which should have been no more than 6" underground but which turned out to be much, much deeper. Ser Percival The Energetic was a big help, as you can see.
::hours passed, YS dug and dug::
YS felt badly about having to destroy some plants. I told him plants are like children; you can always have another one.
He was not impressed.
The pump-out access cover was 31" underground. The installation diagram filed with the county when it was installed said that it should be no more than 6" underground. Oops.
* The gory details, which you may skip if you want. There is not enough room at the same elevation as the house to put in a drain field**, so it was put at the top of the hill behind the house. Septic tank has two chambers. The drains from the house go into the first, the *settling* chamber; when the liquid reaches a certain level it drains into the second, the *liquid* chamber, where a pump pushes that liquid up the hill.
** Original drain field was actually on neighbor's property. We decided that was not a good thing and so had the new one put in.
