Maintaining Water Quality in the Distribution System


SUMMARY: Many water distributions systems constantly struggle to balance demand with water quality. Oversized piping for fire protection, coupled with reducing demand from users have resulted in insufficient demands to maintain minimum disinfectant residuals. Failure to maintain a minimum disinfectant residual in water lines, in addition to being a violation of State and Federal standards, also contributes to the conditions that favor growth of biofilms with in distribution lines. Long-term exposure to low disinfectant residual conditions within a water pipeline not only favors the potential for biofilm growth, it increases the demand for disinfectant dosing and makes it more difficult for operators to maintain desired minimum disinfectant residual levels. A preventative maintenance and control plan requires full understanding of hydraulics to simulate or predict water age, disinfection methods, growth of disinfectant by-products and impacts of water storage. This seminar will address common cases of water quality degradation in a distribution system and suggest tools and processes for optimizing flow and water consumption. Topics include disinfection methods, hydraulic modeling, tank turn over strategies, uni-directional flushing and continuous automated flushing. Panel will facilitate open discussion with class and use real life strategies, including research from the Water Research Foundation that participants can take back with them and utilize in their own systems.
