When crews on Spruce Street dug to replace a modern water main on May 3, 2017, they unearthed a wooden pipe that had been buried for more than two centuries.
Historical consultant Adam Levine traced the pipe’s origin to 1812, noting that the shaft’s oak fibers matched those used in the city’s earliest distribution system.
A Watering Committee report dated 5 November 1812 records the pipe’s installation between October 1811 and October 1812, marking the first phase of Philadelphia’s water infrastructure.
Cast‑iron mains began lining the city in 1819, and by 1832 the department had stopped using wood entirely; the Spruce Street pipe was replaced in 1831 and finally retired by 1858.
The find now joins the PWD’s collection of over 30,000 historical items, enriching the narrative of the city’s early infrastructure.
The department has long dispelled myths that any customers are still served by wooden mains, citing the old pipes’ inability to withstand modern water pressure.
