Document Description
Note: Review Per Lead Zone 7 is proposing to construct new facilities and modify and replace existing ones at the Patterson Pass Water Treatment Plant to incorporate ozonation disinfection technology in its potable water treatment processes and to increase production capacity and finished water storage capacity. Ozonation disinfection technology has been identified as one that would be most effective to improve taste, remove odor, and maintain or improve overall water quality for water consumers in the Zone 7 service area. In addition to improving taste and odor, ozone is more effective than other water treatment technologies (such as powered activated carbon, chlorine and chloramines) in addressing algal byproducts.
