SPUR strongly supports efforts to conserve water and to use alternative supplies for appropriate, nonpotable uses. This effort to expand San Francisco's successful voluntary onsite reuse program, allowing nonpotable water systems to be shared between two or more parcels, will effectively expand this successful program to the district scale. Establishing a clear process for district-scale water reuse today will help the city lay the groundwork for the sustainable infrastructure and eco-districts of tomorrow.
