Distribution System Optimization Pilot Training in Pennsylvania

This post was originally published on this site

On March 28th, the Optimization Team partnered with the Pennsylvania Department of Environmental Protection (PA DEP) to conduct a training workshop on Distribution System Optimization (DSO) for parent and consecutive water systems that use chloramine disinfection.  This was the second in a series workshops designed to improve water quality in chloraminated water systems.  The topics included an introduction to chloramine chemistry and nitrification, a review of operational control strategies to improve water quality, and updates from each of the seven systems about their activities since the previous meeting.  Potential future topics include managing storage tanks to improve water quality, implementing a disinfectant conversion, and anticipated compliance concerns with PA DEP’s new minimum disinfectant residual requirement.  The next workshop is tentatively planned for Summer 2018.
