This powerpoint presentation begins by presenting a brief overview of the Santa Clara Valley Water District (SCVWD). The District's motivation included: expand recycled water use, diversify water supplies, meet Board policy targets; secure a global-warming proof/drought-proof supply; expand non-potable use over certain sensitive areas that currently don't use recycled water; and, open the door for future indirect potable reuse in the county. Objectives of advanced recycled water treatment facilities (ARWTF) included: meet target SBWR recycled water TDS concentration of 500 mg/L; and, meet current max week SBWR recycled water demand. Major components of the ARWTF included: membrane filtration; microfiltration; ultrafiltration; reverse osmosis; and, ultraviolet disinfection. A capacity evaluation summary is presented, along with treatment trains for both dry and wet weather. Includes table, figures.
