Catskill-Delaware UV Facility Opening Ceremony

October 8th, 2013, marked the opening of the NYC Catskill-Delaware UV Disinfection facility which will treat 2.24 billion gallons a day (BGD) of water. This is the largest drinking water UV installation in the world, and it uses TrojanUV technology. We are proud to be a part of this ground-breaking project.

The Facility
In 2005, we were selected as the manufacturer for the UV portion of NYC drinking water project. In 2009 and 2010, we delivered 56 TrojanUVTorrent™ UV units to the Catskill/Delaware UV Facility. Each unit is capable of delivering a 40 mJ/cm 2 dose to 40 million gallons of water per day (MGD).

This disinfection requirement, set by the NYC Department of Environmental Protection, delivers greater than 3-log reduction of microorganisms, such as Cryptosporidium and Giardia. We custom-designed our TrojanUVTorrent™ in order to meet the challenging design parameters of this unique project.

The Catskill/Delaware UV Facility is located in Valhalla, New York. The treatment train consists of screening, UV treatment, and chlorination (for a residual disinfectant in the distribution system).
