Follow the road southwest from Echo Lake Lumber to find a pipe next to the wrecked truck with its rear wheels stuck in the pond. Enter the pipe to find a sleeping feral ghoul and the entrance to the pump control, which requires the worn key.
The pump control is a small, mildly radioactive room containing a bed and a shrine. It is the hideout location for Confessor Martin.
- Mother icon on the shrine.
- A New Path on the shrine.
- Sister Gwyneth's visit on the shrine.
- What Atom Requires on the shrine.
- An Execution at the foot of the bed.
