Document Description
The project involves the full build out of the advanced water purification facilities at the existing terminal island water reclamation plant. Components of the planned AWPF include: microfiltration influent pumps adjacent to existing MF influent pumps; MF expansion immediately adjacent to the existing MF area under a new canopy structure; reverse osmosis trains immediately adjacent to the existing RO trains under a new canopy structure; RO feedwater tank and pump station; and equalization tank constructed north of the MF influent pumps on the Plant. With implementation of the above improvements at TIWRP, the export of reclaimed water from TIWRP would increase from a max of 5 million gallons per day to a max of 12 mgd. The main user of the reclaimed water is the Dominguez Gap project for groundwater injection. Additionally, potable water use reduction is anticipated for other potential users, including Machado Lake, Harbor Generating Station, and Harbor Irrigation.
