August 9, 1911: Municipal Journal article. Building a Large Vitrified Clay Pipe Sewer. “A piece of sewer construction is nearing completion in Brooklyn, N. Y., which is remarkable, both for the fact that it is believed to be the largest vitrified pipe sewer ever built, and also it is being laid with comparative ease in fine sand 10 feet to 15 feet below tide water level. This sewer, which is about 4,000 feet long, serves as the outlet line for a system draining a considerable area of a new part of the city which is rapidly extending out over the meadows adjacent to Jamaica Bay. It ends at a sewage disposal plant which has been in service for about 18 years and is enormously overtaxed and must speedily be replaced with some larger and probably different kind of plant.
The sewer is being laid through salt meadows, a considerable part of which is overflowed by the highest tides, and at few if any points is the land more than 3 feet higher than this. The depth of the trench ranges from 12 to 16 feet, or about 10 to 13 feet below high tide…. The sewer is made of 42-inch vitrified clay pipe 3 inches thick, bedded in concrete up to the horizontal diameter, this concrete having vertical outer sides and resting upon a plank platform, and being 7 inches thick under the invert and 14 inches wider than the outside diameter of the pipe barrel. For the purpose of connecting future buildings there are inserted at intervals of 20 feet upright “standpipes” of 6-inch vitrified pipe which rest on the 42-inch pipe in sockets formed around openings in the top of the pipe constructed for this purpose.”
