The sewage of Baltimore City is pumped to the sewage plant at Back River in Baltimore County, where it is ‘cleaned’ and then discharged into the river. Interesting fact about the below photos from a 1955 report is this – “A number of leaks were repaired in the wood stave discharge pipes by a diver. The pier at the river, which had been damaged by hurricanes was rebuilt.”

As the photographs from the early 1900s show, the discharge pipes are above the water? So were they lowered into the water after assembly? That seems unlikely as there are hundreds of adjusting bolts holding the pipes into the air? Maybe I will find the answer one day in the many reports still to be read…
