This paper reports on the validation
program of ultraviolet (UV) disinfection equipment for the City of New York and the unique set of
challenges that have been addressed.
The design of a UV disinfection facility for New York City's Catskill and Delaware supplies
poses several unique challenges due to the scale of the facility (2,020 mgd), the unfiltered state
of the water being treated and the relative infancy of UV technology. Challenges that have been
encountered include the need to provide a facility with the following criteria:
it meets the required design goals under all potential operating conditions and raw water
qualities;
is highly reliable; and,
maintains the present operational flexibility of the system.
Additional challenges in designing the world's largest UV disinfection facility include
maintaining a schedule ahead of regulatory promulgation, maintaining operational flexibility in
the overall system both now and in the future and ensuring that the UV equipment that will be
provided for this facility can be validated to meet the design criteria. There is currently no
facility world-wide large enough to validate units of the capacity to be used for the Catskill and
Delaware Facility. Until recently, it has been believed that validation of large-scale UV units was
not technologically or economically feasible. This paper addresses how DEP has addressed these
challenges to validating large-scale UV equipment.
