Planning Ahead
In the 1910's the Catskill Aqueduct engineers designed the system to have periodic drains so segments could be cleared and inspected. Now a hundred years later, and with the new third tunnel complete, maybe that will begin to happen!
DESIGN:
The grid design was a standard in the late 1900's and the designer added a small square in each coffer to keep things peppy.
UTILITY:
This is a drain of a major distribution main emerging from the end of the aqueduct near Ft. Greene Park.
RANGE:
This example is on State St. between Third and Flatbush Avenues in Brooklyn. There are many similar covers throughout the city.
