Document Description
As part of the disinfection process, Zone 7 uses chloramination to minimize formation of disinfection byproducts ad chlorinous taste and odors, and to maintain a disinfectant residual in the distribution system. The proposed project includes the removal of the existing gaseous ammonia system at the Patterson Pass Water Treatment Plant (WTP) and replacement with an aqua (or liquid) ammonia system (using a 19 percent ammonia solution). The existing gaseous ammonia delivery components are near the end of their service life and the proposed project is intended to replace the existing system in order to improve the reliability of plant operations and employee and public safety. New facilities proposed under the project include an aqua ammonia tank and storage building, a chemical fill station and underground containment structure, and two additional feed lines. No substantive changes in treatment plant capacity or operation are anticipated as part of the proposed project.
