Abstract:

This presentation describes ongoing work focused on optimization of drinking water distribution systems for disinfection and disinfection byproduct (DBP) control. New DBP regulatory requirements which are moving toward locational (site-specific) health-based DBP limits as early as 2012 (USEPA 2006c) are requiring utilities to look more closely at the distribution system to understand DBP formation and control factors. Recent and ongoing EPA distribution optimization field studies are highlighted here, where water systems are being intensively evaluated to understand disinfection products-related factors. Disinfection and DBPcontrol-related work in a 2007–2009 Water Research Foundation, formerly American Water Works Research Foundation, project entitled “Criteria for Optimized Distribution Systems” is described here as well. In the latter project over 150 water professionals from over fifty water systems are working together with the research team and project advisors to develop widely useful, simply applicable optimization criteria and assessments for drinking water distribution systems. Through these combined efforts, chlorine residual is evolving as a useful optimization criterion which will also be helpful in efforts to control disinfection byproducts and total water quality.
