Story summary

In May 2017, workers in Philadelphia uncovered wooden water mains dating back to around 1812 while replacing a water main along the 900 block of Spruce Street. Adam Levine, a historical consultant for the Philadelphia Water Department (PWD), determined that these pipes were part of an early infrastructure development phase. Records from the city's Watering Committee showed that a pipe was laid "Back of Spruce, from Ninth to Tenth" between October 1811 and October 1812. This discovery highlights the historical transition in Philadelphia’s water system before the shift to cast iron pipes and the construction of the Fairmount Water Works.
