the Dobson's Run Storm Relief Sewer was nearing completion, I had the chance to
walk in the pipe as it neared completion. We were lowered down to the level of
the pipe, about 100 feet underground, in a metal elevator cage attached to a crane.
Once in the 12.5 foot diameter pipe, we saw the crews at work grouting and doing
other finishing work prior to putting the sewer into
The photographs below show the construction of the original Dobson's Run Sewer from the 1912 Annual Report of the Bureau of Surveys, Department of Public Works. As with the current pipe, parts of this sewer were also done in tunnel.
