Sometimes, when people find out about my professional work with sewage systems, they ask, “Oh, yeah, where does everything go when it goes down the drain? If you live in New York City, there’s a good chance it all goes here:
to the Newtown Creek water pollution control plant run by the NYC Department of Environmental Protection. This is one of the largest wastewater treatment plants in the world, and I was there for a meeting this morning. Afterwards, I took a stroll around the perimeter to get a view of the beautiful digesters, shown at the head of this post, that turn the residue of the treatment process into methane gas and inert sludge. The shape of the tanks is quite innovative, and the DEP is very proud of them. [In the aerial view, the digesters are on the right, under construction.] At night, they are illuminated in their waterfront setting with blue searchlights. These treatment plants are like ‘negative’ farms: they use natural processes, aided by technology, to break down, rather than grow up, organic matter.
The public investment in facilities like these is enormous, and largely unremarked. This plant is being enlarged and upgraded to the tune of about one billion dollars. Lot’s of money is spent on sewage and drinking water, although not always wisely.
In the USA, the Clean Water Act of the 1960s was the impetus for a vast program of construction all across the nation to clean up urban waterways. When I first came to NYC in college, it was not quite finished: the entire west side of Manhattan dumped its raw sewage into the Hudson River, and on a warm summer night, it stank! A new treatment plant went on line there in the 1980s, and now all of NYC wastewater is treated, except when it’s raining (but that’s a story for another post.)
Consider this: The waters around the city, in the Hudson and the East River, are easily cleaner than they have been in 100 years, despite the greatly increased population in the surrounding region. In those bygone days of yore, when handsome lads would cool off in the summer with a dive off the East River docks, more likely than not they were dunking themselves in a pretty filthy brew. Now it’s clean, although some people have a hard time believing it.
I came across this rather forlorn remnant of local national pride during my walk around the plant.
