Water Pipe Full of Crap - Originally uploaded on flickr by stevegarfield.
This is what a water pipe looks like after years of providing drinking water to a neighborhood of Boston.
Before using this type of modern pipe they used hollowed out trees!
"In 1795, private water suppliers developed a delivery system, using wooden pipes made from tree trunks, to carry water from Jamaica Pond to Boston Proper."
