Distribution System Comprehensive Performance Evaluation

During the week of June 10th, members of the Optimization Team, in partnership with Pennsylvania Department of Environmental Protection’s (DEP) Distribution System Optimization Coordinator, provided training to additional DEP staff on the Distribution System Comprehensive Performance Evaluation (DS CPE) protocol.  This CPE training event enhanced understanding of distribution system related issues (especially related to water quality), which will help with the implementation of “regular” drinking water program activities.  The trainees provided excellent feedback on potential applications and implementation of the DS CPE protocol.  In the near-term, DEP staff hope to use elements of the DS CPE to provide Stage 2 DBPR compliance assistance to water systems.  Longer-term, it’s possible that the DS CPE could be incorporated into their established Filter Plant Performance Evaluation program, which could have a significant positive impact on distribution system water quality. Participants described the DS CPE as an excellent training tool for state staff, and the training approach used could be effective in other AWOP states or Regions.   (Alison Dugan and Matthew Alexander, US EPA TSC)

Region 10 AWOP Training and Strategic Planning Meeting

The TSC optimization team, in partnership with US EPA Region 10 and ASDWA, facilitated a meeting and technical training event via web conferencing on June 18-19, 2013.  Participants included representatives from Alaska, Oregon, Utah and Washington.  The technical training included additional data analyses from a workshop conducted previously on membrane treatment optimization in cooperation with the City of Warrenton, OR. 

The Washington Department of Health reported on its efforts to implement turbidity data-integrity activities on an area-wide basis through its regional office staff.  These efforts engage water system operators in assessing the accuracy and consistency of the turbidity data being maintained at their facilities over the entire life cycle of the data (i.e., sample collection through reporting).  Operators have been very appreciative of these state activities, often making immediate adjustments to improve the integrity of the data being generated.  The state plans to prepare a report of its findings in an upcoming department newsletter.
