This powerpoint presentation begins by providing a brief overview of Union Hills Water Treatment Plant (UHWTP) located in Phoenix, Arizona. A project to optimize its current processes and understand potential process limitations so that further process upsets may be averted is presented, and project objectives included: define operational water quality scenarios for three plant conditions (normal - turbidity <5 NTU, stressed - turbidity = ?, and extremely stressed - turbidity = ?); evaluate current treatment process limitations; and, recommend operational strategies and process improvements to meet water quality and demand objectives. The objective of this presentation was to summarize UHWTP source water quality, including UHWTP Raw Water, upstream CAP sample locations, Bill Williams River, Agua Fria River, Colorado River, and Lake Pleasant. Includes figures.
