Automated Disinfectant Generation And Control Systems Produce Consistent Residual Levels In Aqua Pennsylvania's Distribution System

Aqua Pennsylvania (Aqua PA), an Aqua America subsidiary, serves more than 1.4 million people in 32 counties across Pennsylvania. Aqua PA has significant experience using chloramine chemistry to mitigate trihalomethane (THM) disinfection byproduct formation in its many distribution systems. As with most water utilities, this traditionally meant constant monitoring and unplanned operator callouts to adjust influential water storage tank disinfectant residual levels, particularly in the summer.
