This powerpoint presentation outlines information on simultaneous compliance implications of current regulations. AwwaRF Project 3115:"Decision Tools to Help UtilitiesDevelop Simultaneous Compliance Strategies" is presented with the objectives of:Identify and Organize Conflicts andUnintended Consequences; Sort Technology and Optimization Strategiesaround Conflicts/UICs;Develop a Decision Framework using"Technology-Based Rules"; and,apply framework and rules to "web-basedTool" to help frame treatment decisions. Topics outlined include: optimization of utilities; natural organic matter (NOM) treatment/removal for disinfection byproduct (DBP) control; positives and negatives of NOM removal technologies; transitional impacts are often overlooked in planning; Central Arizona Project in Tucson, Arizona; Washington Suburban Sanitary Commission (WSSC) implements enhanced coagulation; and, Palm Beach County Water Utilities Department switches to nanofiltration (NF) softening. Lessons learned include:operations increasingly complex and flexibility is shrinking;potential for unintended consequences is rapidlyincreasing;most utilities would rather tweak than switch treatment, butStage 2 will require lots of new technology;tweaks may be less capital cost, but often requiresignificant increases in O&M costs;any change has potential for negative unintendedconsequences;transitional WQ must also be managed;"Compliance Monitoring Data" is frequently insufficient topredict impacts of modified treatment/operations, anddiagnose the real cause of distribution system WQ excursions.
