Sealing septic tank
The excavator climbed inside and sealed up the weeping hole. The maker leaves a tiny hole in order for water to seep out while the tank sits in the yard waiting to be sold. This way the tank doesn't fill up with water which would make for a heavy and troublesome load. On the building site the hole gets filled with a stub of pencil and then coated with thick tar.
