You Find the Darnedest Things in Portland Sewers

A natural gas line was bored through the existing sewer line.Sewer scopes reveal all sorts of things: cracks, roots, clogs, transitions from terracotta to cast iron, and even completely shattered or nonexistent lines.  This was a new one for us: the yellow conduit at the top of the sewer houses an active gas line!

Portland’s sewer system is decades old but people are still converting their houses from oil to natural gas or building new houses with natural gas.  The sewer lines aren’t always exactly where expected and in this case, the new gas line conduit was bored by machine, not laid in an open trench so the nobody ever saw the sewer line.
