Your Water and Sewer Fees at Work

Your Water and Sewer Fees at Work

New York City has invested in its water and wastewater systems for more than 150 years, and most of that infrastructure has served the people of New York for more than a century. DEP is continuing that tradition with the most comprehensive upgrades to the City’s water and wastewater systems in decades. These projects will serve New Yorkers for generations to come.

The following brochures cover what major capital investment projects are going on in each borough:

DEP has made a variety of improvements throughout the system. Among the recent, ongoing, and planned capital investments are:

Major Capital Construction Projects at DEP

The following projects represent the most significant investments in the future of the City’s drinking water system since the construction of City Water Tunnels 1 and 2—which date from 1917 and 1936:

Major Construction Projects

In addition to the Citywide projects for improving New York’s water supply, DEP is investing heavily in wastewater and harbor water infrastructure projects throughout the five boroughs and watershed:

$4.8 billion to construct the Croton Water Filtration Plant and the Catskill/Delaware Ultraviolet Light Disinfection Plant

Ten percent of the city’s water comes from more populated sections of Westchester and Putnam Counties, where local development can affect the drinking water. The Croton Water Filtration Plant will ensure that water from these areas continues to meet the city’s high water quality standards. The Catskill/Delaware Ultraviolet Light Disinfection Plant provides a second means of disinfection to the other 90% of the city’s drinking water supply, treating microbiological agents like Cryptosporidium and Giardia.

$4.7 billion to build City Water Tunnel 3

The city currently relies on City Water Tunnels Nos. 1 and 2 to deliver the majority of drinking water within the city. These tunnels were first put into service in 1917 and 1936, respectively. Completing City Water Tunnel No. 3 will provide New York with critical supply capacity, and will allow DEP to repair City Water Tunnels Nos. 1 and 2 for the first time in their history.

$3.8 billion to upgrade wastewater treatment plants

To upgrade our wastewater system, the city is investing $65 million in the Rockaway WWTP. In the early 1990s, DEP began a $5 billion upgrade of the Newtown Creek WWTP. The Newtown Creek Plant is located in Greenpoint, Brooklyn, and serves parts of Queens.

$1.2 billion to decrease the amount of Combined Sewer Overflows from entering New York City’s Waterways

The new $151 million Alley Creek CSO Overflow Tank will capture, retain, and pump up to 5 million gallons of overflow to a wastewater treatment plant before the stormwater can affect our environment. DEP’s water and sewer improvements include a $30 million upgrade to the Douglaston Pumping Station, which will alleviate street flooding.

$129.1 million to construct the Staten Island Siphon

To provide Staten Island with critical supply capacity, the City will construct the Staten Island Siphon, a new water main measuring 6’ in diameter that will be buried deep in the seabed of New York Harbor. The new siphon will replace the two existing smaller siphons that will likely be affected by plans to dredge the area. The new siphon will have sufficient capacity to meet Staten Island’s entire average and peak demand.

CAT-252 - Replacement of the Esopus & Route 28A Railroad Bridges

Due to the deterioration of existing concrete, both the Esopus Bridge, and Route 28A Railroad Bridge, need to be entirely replaced.
