Red Hook Sewer Map, 1975 and Today

By The Red Hook WaterStories team

This Red Hook Water Polution Control Sewer Map from 1975 shows the existing sewers at that time.

The map shows four sewer lines ending in Atlantic Basin. Pipes discharging into the harbor, or other bodies of water, are known as Combined Sewer Overflows, or CSOs for short. Sewer lines are connected to street drains. During heavy rains, for example, the system gets more water than it can handle and the overflow goes - untreated - right into the harbor.

New York State provides a digital map of Combined Overflows. Zoom into Red Hook to see the outflows there.

Open Sewer Atlas NYC, provides a similar map of the sewershed.
