(NEW YORK, NY – August 22, 2013) – The Catskill-Delaware Ultraviolet Disinfection (Cat-Del) Facility, the largest UV disinfection facility in the world, has won the award for ENR Best Project in the Water/Environment category and is a finalist for Best Overall Project, which will be awarded in November.

The facility, which previously won an ACEC National Grand Award, treats and controls the flow of more than two billion gallons of water per day to nine million consumers in and around New York City and represents a tremendous leap forward in water treatment technology.

The Cat-Del Facility utilizes ultraviolet light disinfection to provide protection from Cryptosporidium and Giardia (organisms that can cause gastrointestinal illness). UV light, traditionally used for wastewater disinfection, had rarely been used in this country for water treatment and has never been applied at anywhere near the massive scale required to meet New York City’s demand. The design also includes the largest flow control energy dissipating valves of their type ever made. The Cat-Del Facility houses sixteen 84-inch valves that can pass high flows at low head loss and feature reliable throttling capability.

The use of UV light was proven to provide the necessary protection at a cost estimated to be one quarter that of a filtration plant of the same capacity. Additionally, this facility poses fewer impacts to the environment than a filtration plant, due to a shorter construction period, considerably smaller footprint, and significantly lower power requirements.

The ENR Best Projects Awards are a series of special events to celebrate and honor the building teams that created the best projects of 2013 nationwide. These extraordinary projects are selected by juries of local prominent industry professionals. The awards breakfast will be held on November 6th in New York City.
