The National Water Research Institute has published the third edition of its Ultraviolet Disinfection Guidelines for Drinking Water and Water Reuse. The guidelines are designed to provide regulatory agencies and water and wastewater utilities with a common basis for evaluating and implementing ultraviolet (UV) disinfection. The UV Guidelines were originally prepared in 2000. Revisions in the Third Edition of the UV Guidelines reflect experience gained from the application of the guidelines over the years.
