55 miles of Albany’s 376 miles of water mains were installed in the mid-19th century. However, some of the mains may even be older, with some cast iron mains possibly installed in 1813. If true, Albany would have the oldest functioning cast iron pipe in the western hemisphere.
Incidentally, all of the water mains in the City originally were hollowed-out tree trunks, many installed in the 1700s. Although unlikely, there is a very remote, outside chance that somewhere beneath some of the oldest parts of our City, a functioning wooden water main remains.
