This slide presentation outlines information on the development of a distribution system management plan to: reduce disinfection byproducts; improve residual maintenance; and, preserve high aesthetic water quality. There were three components of the project. The first was distribution water quality assessment, including evaluation of current corrosion control program, and identification of opportunity for improvement. The second part of the project was pilot testing for corrosion control, including evaluation of alternative pH conditions, chloramines vs chlorine, and corrosion inhibitors. The third part was pilot testing for nitrification control, including an assessment of pH control, ammonia control, chlorite, and chlorine for controlling AOB propagation.
