Unintended Consequences in the Distribution System

Recent water quality regulations, such as the LT2ESWTR (Long Term 2 Enhanced Surface Water Treatment Rule) and the DBP (Disinfection By-Product) Rule, and others have forced utilities to make process modifications at their water treatment plants (WTPs). These changes range from process changes, such as going from conventional treatment to membranes, to disinfection changes, such as going from chlorine to chloramines, or even chlorine gas to sodium hypochlorite. What is the impact of these process changes on water chemistry and lead and copper control? This presentation provides case studies from a number of Midwestern utilities that have faced unintended consequences challenges relative to corrosion control in the water distribution system.
