This article discusses a full‐scale tank retrofit by the Los Angeles Department of Water and Power (LADWP) that included suspending a bank of fluorescent blacklights in the headspace of Mount Washington Tank 2 to prevent nitrification from occurring in the covered storage facility. The article explains the process by which nitrification was occurring after LADWP changed from chlorine to chloramines as its secondary disinfectant, and discusses the full‐scale pilot project along with near‐ultraviolet (UVA) radiation lighting design and validation.
