The nearly 13 million gallons a day of recycled water delivered through the pipeline boosts Calpine’s power production by 100 megawatts, equivalent to providing power to nearly 125,000 homes.
Santa Rosa Utilities is celebrating the 10 year anniversary of the Santa Rosa Geysers Recharge Project -- a 41-mile long recycled water pipeline that connects Santa Rosa’s Subregional Water Reuse System to Calpine Corporation’s Geysers geothermal steamfields in the Mayacmas Mountains.Santa Rosa’s Subregional Water Reuse System is responsible for the recovery and advanced treatment of approximately 17 million gallons per day of wastewater from Santa Rosa, Rohnert Park, Cotati, Sebastopol, and the South Park Sanitation District. In a normal year, approximately one-third of the advanced treated recycled water is used for agricultural and urban irrigation and the other two-thirds is delivered to Calpine’s Geysers steamfields via the Geysers Recharge Project pipeline.
To date, the Geysers Recharge Project pipeline has delivered over 42 billion gallons of Santa Rosa’s recycled water to Calpine’s geothermal steamfields. The nearly 13 million gallons a day of recycled water delivered through the pipeline boosts Calpine’s power production by 100 megawatts, equivalent to providing power to nearly 125,000 homes.
