Can onsite water reuse systems be successfully integrated with a community’s centralized treatment system? New legislation is being adopted around the country to remove barriers to onsite water reuse and communities like San Francisco are leading the way in demonstrating how onsite non-potable water systems can supplement centralized treatment and extend water supplies. This presentation will discuss important lessons learned in San Francisco, which has been requiring onsite water reuse in new large developments for seven years. You will also learn how model legislation developed by the National Blue Ribbon Commission for Onsite Non-potable Water Systems is being adopted across the country to encourage the use of alternative water supplies. The presentation will also provide a preview of the National Blue Ribbon Commission’s new training manual for onsite reuse, which will be released in early 2020, and discuss future research priorities aimed at advancing more widespread adoption of onsite non-potable water systems.
