Most of that is for cleaning the mirrors. That is a lot less than other generator types (solar and conventional). See the PDF document: "Low Water Use: BrightSource’s solar tower technology uses up to 95% less water than competing wet cooled solar thermal plants by employing a dry-cooling process, which uses air instead of water to condense steam. The steam production cycle is a closed loop system, with all water recycled back into the system, while general conservation measures help to further reduce water usage. The water consumed on the project is for cleaning the mirrors, much like a PV plant of similar size." - Jed
