Torresdale Conduit work gang, 1906

A work gang plugging leaks in the 10'7" diameter Torresdale Conduit, December 18, 1906. This massive pipeline, 2.5 miles long, was built to carry filtered water from the Torresdale Filters to the Lardner's Point Pumping Station; fourteen men died during its construction. Both the filters and the pumping station were the largest of their kind in the world when they were built. Delays and accusations of corruption plagued the works at Torresdale, which were not in full operation until 1909.
