This paper discusses AwwaRF Project 2875, Development of Distribution System Water Quality Optimization Plans, that was conducted as a tailored collaboration between AwwaRF and several participating utilities including Greater Cincinnati Water Works in Ohio, Calgary Waterworks in Canada and the City of Everett, Washington. The Distribution System Water Quality Optimization Plan (DSOP) is a tool utilities can use for evaluating and improving programs that affect distribution system water quality; evaluating conditions within the distribution system to reduce the potential for contamination; creating better documentation; and enhancing communication between the various utility functions that impact water quality in the distribution system. It should address both regulatory compliance issues and customer issues related to aesthetic properties of drinking water. The DSOP should be considered a living document that is continually updated as new information becomes available or as the utility has resources to further develop related programs and practices. The DSOP could be used to optimize all distribution system functions or to target a few specific distribution system programs for water quality improvements. The DSOP is envisioned as a 3-ring binder with tabbed sections or alternatively, it could be an electronic document available to utility staff via an intranet. The DSOP includes the following topics: water quality goals and monitoring; operations management; maintenance management; facilities planning and engineering; construction practices and inspection; training; customer relations and communication; and, data integration for water quality management. The focus of each topic is on determining the impact of utility practices on distribution system water quality, and providing a framework for integrating water quality considerations into utility planning processes and programs.
