Agitors and Maxcretes Handle Harsh Concrete Mix in NY City Water Tunnel

The New York City Water Tunnel No. 3 is the largest capital construction project in New York City’s history. Constructed under the direction of the New York City Department of Environmental Protection (DEP), the completed tunnel will stretch over 60 miles and take 50 years to construct in its entirety. When completed, City Water Tunnel No. 3 will join Water Tunnels No. 1 and No. 2 in supplying water from reservoirs in Upstate New York to the residents in all five boroughs of New York City.

City Water Tunnel No. 3 is being constructed for 2 primary reasons.

  1. Water Tunnel No. 1 and 2, placed in service in 1917 and 1936, respectively, have not been inspected and repaired since they were opened. By constructing and opening No. 3, the city will be able temporary close the original two tunnels for inspection and repairs while No. 3 continues to supply water to the city.
  2. With the continued growth of New York City’s five boroughs, a third tunnel will be needed to supply water to the larger population.
