Well apparently I can’t post a link here. I’ll try again in the comments.
Crews in Albany, NY recently uncovered an abandoned section of water main. What makes it interesting is that it’s a main made from a hollowed out log that dates back to the 18th century. While this main was no longer in use there are areas of the country that occasionally uncover wooden mains that are still in service.
The reason they were in the area is interesting for its own reason. They had recently discovered a building in the area was never connected to the city sewer system that was installed in 1913. Instead it was discharging it’s waste straight to the river for over 100 years; oops.
