This paper presents the process and conclusions of the Failure Mode and Effects Analysis (FMEA) that assesses the critical control points and risks of ultraviolet (UV) disinfection. The FMEA was completed to support the development of the interactive UV Disinfection Implementation Tool (UVDIT). The UVDIT is being developed as part of the American Water Works Association Research Foundation (AwwaRF) Project #2861, Integrating UV Disinfection into Existing Water Treatment Plants. The FMEA results will be used in conjunction with the information gathered from a utility survey and power quality analysis to develop the UVDIT. The UVDIT will assist utilities in determining the feasible retrofit locations of UV disinfection, the risks at the retrofit locations, method for mitigating those risks, and conceptual retrofit and risk mitigation costs. Includes 3 references, tables, figure.
