In 1998, the City of Santa Rosa entered into a 30-year agreement with a consortium of geothermal companies to supply highly treated recycled water from the Laguna Treatment Plant for injection at the Geysers.

The Geysers Recharge Project involved the construction of a 41-mile pipeline, four pump stations, a terminal reservoir, and associated control/communication systems. The pipeline route for the Geysers Recharge Project passes through Windsor west of US Highway 101.

In July 2008, the 1998 agreement was amended, anticipating increased flows including Windsor’s for an additional 30 years. Today, Santa Rosa pumps about 13 MGD of recycled water to the Geysers where it is used to create enough green energy for approximately 100,000 homes.
