This powerpoint presentation outlines information on simultaneous compliance implications of current regulations. AwwaRF Project 3115:
"Decision Tools to Help Utilities
Develop Simultaneous Compliance Strategies" is presented with the objectives of:
Identify and Organize Conflicts and
Unintended Consequences;
Sort Technology and Optimization Strategies
around Conflicts/UICs;
Develop a Decision Framework using
"Technology-Based Rules"; and,
apply framework and rules to "web-based
Tool" 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 rapidly
increasing;
most utilities would rather tweak than switch treatment, but
Stage 2 will require lots of new technology;
tweaks may be less capital cost, but often require
significant increases in O&M costs;
any change has potential for negative unintended
consequences;
transitional WQ must also be managed;
"Compliance Monitoring Data" is frequently insufficient to
predict impacts of modified treatment/operations, and
diagnose the real cause of distribution system WQ excursions.
