It is interesting to note that some of the old sewer systems are unmapped in
Puerto Rico, and I read that the U.S. National Park Service is mapping some
of the old systems or supplying money to. I read also that the first use of
COGO (in the world?), computer based Coordinate Geometry, was done by IBM to
site out a sewer network on the island of Puerto Rico involving a huge
amount of RAM (random access memory) on the order of 32K! Probably the data
was stored on a hard disk platter a meter or more in diameter! I once saw
one hanging on a wall back when 5 1/2 inch disks were making an entrance, to
replace an HX-20 notebook computer that had assisted Anna Roosevelt, Ph.D.,
in mapping a mound complex in the Amazon River, on the Island of Marajó in
Brazil, which worked fine there, but succumbed to the humidity of the Hudson
Valley while in use by Greenhouse Consultants, Inc. at the Wickers Creek
Site.

>Sewers, they must be hard to run without water!

In the Bronx, NYC, there has been an ongoing conundrum over the placement of
a Federally ordered filtration of reservoir water. Currently, the proposed
filtration plant is in three locations, 1) along the Harlem River,
The Harlem River is a tidal strait in New York City that flows 8 miles
between the East River and the Hudson River, separating the borough of
Manhattan from the Bronx and Queens. Part of the current course of the
Harlem River is the Harlem Ship Canal, which runs somewhat south of the
former course of the river, isolating a small portion of Manhattan (New York
County) on the Bronx side of the river.

2) in the middle of a city park, and 3) alongside a prison in Westchester
County. The preferred site has been the "public taking" of the park,
currently a public golf course in the park.

Originally, it was to be alongside Bronx's High School of Science, Lehman
Community College, and a historic neighborhood, in the reservoir currently
there. Has anyone on the list heard of the public taking of parkland for
Federal compliance? (besides the former Federally funded sewer projects).
