Optimization Program – Microbial Performance Based Training in West Virginia

The Optimization Team, in collaboration with the West Virginia Bureau of Public Health, facilitated the fourth of six sessions of microbial PBT at the Summersville, WV City Hall on September 11, 2012.  Operators from the participating water systems reported on their efforts to calibrate their jar testing process to simulate the coagulation, flocculation and clarification processes existing in their respective water treatment plants.  This exercise resulted in a better understanding of existing treatment processes and identified opportunities for enhancing performance.  Further opportunities for improving performance were identified in a workshop and studies will be implemented by the participating operators before the next session. This PBT session also provided a forum for the development of strategies to address the unique water quality and chemical cost issues resulting from this year’s drought conditions.  (Ouro Koumai & Rick Lieberman, US EPA TSC)

Optimization Program ­­– Distribution System Performance Based Training in Alabama

The Optimization Team, in partnership with the Alabama Department of Environmental Management (ADEM) AWOP members, conducted Session 5 of a Performance Based Training (PBT) project focused on distribution system optimization of a parent system and five of their consecutive systems.  The consecutive system operators, who have historically been focused on water quantity (not quality) have become very aware of water quality in their respective systems, and embraced concepts such as calculated flush time (prior to sampling), tracking/trending water quality through the system to ultimately reduce water age and improve water quality, and the impact of tank operations on water quality.  During Session 5 the participants reported on special studies they conducted to assess the impact of water storage tanks on water quality and toured the water treatment plant to gain a better understanding and appreciation of water treatment – which ultimately impacts water quality entering their respective systems.  (Matthew Alexander & Alison Dugan, US EPA TSC)
