Replacement offices, warehousing space, meeting space and parking will also be constructed on the site. The proposed Oso Creek WRP will treat wastewater generated within the SMWD service area and produce tertiary water that meets State of California Title 22 recycled water requirements for unrestricted reuse. The Oso Barrier URWTP will process urban runoff to be used for irrigation, lake fill, and potable reuse. The URWTP will include prescreening equipment, ultrafiltration, reverse osmosis and UV disinfection. The backwash water will be discharged to the Oso Trunk Sewer for treatment and ultimate disposal from the Latham Water Treatment Plant
