The development and implementation of the city’s flushing program can improve both, water quality and hydraulics. It can improve water quality by restoring disinfectant residual, reducing bacterial re-growth, dislodging bio-films, removing sediments and deposits, controlling corrosion, restoring flows and pressures, eliminating taste and odor problems, and reducing disinfectant demand throughout the distribution system. These efforts should prolong the life expectancy of the distribution system.
