Scope of Work:
ECCO III Enterprises, Inc. completed this project as part of the joint venture team, Skanska-ECCO III-White (SEW), JV.This $1.2 billion project for the New York City Department of Environmental Protection consists of the construction of an Ultraviolet Light Disinfection Plant for the Catskill and Delaware Aqueducts. The facility is the world’s largest ultraviolet light facility, and treats 90% of the New York City water supply. The plant has the capacity to treat up to 2 billion gallons of water per day from the Catskill and Delaware Aqueducts. The contract included over 10,000 linear feet of various types of piping ranging in size from 48 to 144 inches. The major structural components were the north and south forebays which control water flow into and out of Shaft 19 of the Delaware Aqueduct, and water flow diversion to the Catskill Aqueduct system, once treated. The UV Facility Building itself houses four quadrants comprised of 56 UV treatment units, each able to process 40 million gallons of water per day. All controls and valves are fully automated to run through a computerized control system, and are monitored 24 hours a day. This facility is ten times larger than any previously built facility of its kind in the world. |
