On December 11, 2013, the Optimization Team, in partnership with the Alabama Department of Environmental Management (ADEM), conducted the last session of a Performance Based Training (PBT) pilot project focused on distribution system optimization. A parent water system and six of their purchasing systems, which ranged in size from 3,000 to 40,000 served customers, successfully completed the PBT series. All systems realized reduced disinfection byproducts (DBPs), increased chlorine residual, and a decrease in customer complaints throughout their systems. This was largely attributed to optimization at the water plant and efforts in the distribution systems to reduce water age. The operators also gained an “appreciation” of the importance of collecting, tracking and trending water quality data to assess system performance and address water quality issues. During this session trainers provided a summary of distribution system optimization strategies to improve water quality and encouraged participants to continue optimization as an ongoing activity in their systems. The training materials and lessons learned from this pilot are being utilized by Alabama and other AWOP states to train distribution system operators.
