Improve potable water supply reliability for southern Orange County by constructing a local regional water treatment facility.
Collaborate with multiple retail water agencies to optimize treatment capacity and conveyance.
Design facility to treat raw water from three sources, blended or as individual sources.
Utilize modern treatment technology to produce water that meets standards stricter than current regulatory requirements.
Minimize waste by operating the plant at greater than 99% recovery efficiency.
