Where does recycled water come from?
The Santa Rosa Regional Water Reuse System receives and treats wastewater from more than 225,000 residents and 6,500 businesses in the cities of Cotati, Rohnert Park, Santa Rosa, Sebastopol, the South Park Sanitation District, and portions of unincorporated Sonoma County. After entering the Laguna Treatment Plant, wastewater from homes and businesses undergoes a carefully regulated purification and disinfection process, known as tertiary treatment. Throughout the process, samples are taken and tested in a state-of-the-art laboratory to ensure high-quality water.
