Document Title
Del Valle Water Treatment Plant Ozonation Project
Document Type
MND - Mitigated Negative Declaration

Document Description
Zone 7 is proposing to construct new facilities and modify existing ones at the Del Valle Water Treatment Plant to incorporate ozonation disinfection technology in its potable water treatment processes. This technology has been identified as one that would be most effective to improve tast, 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 powdered activated carbon, chlorine and chloramines) in addressing algal byproducts residues. This enhancement to the DVWTP's treatment capabilities would not increase the plant's water treatment capacity.
