The proposed Delta Conveyance Project features a single tunnel with two intakes on the Sacramento River near the City of Sacramento. The water to be carried underground to existing State Water Project (SWP) facilities in the south, where it would ultimately connect to the SWP’s water distribution that. provides drinking water to approximately 5 million homes in California annually. The current system relies is at risk of failing due to future events such as climate change, sea level rise, earthquakes, and flooding. While the proposed Delta Conveyance Project aims to modernize the conveyance of water through the SWP and protect California’s water supply from these risks. The Delta Conveyance Project also aims to provide greater flexibility in how water is diverted, which has the potential to improve protection for at risk species that live and migrate through the Delta.
The Valley Water Board of Directors voted to support the proposed Delta Conveyance Project in October 2019 and voted to provide funding for some of the preliminary environmental review, planning, and design costs in November 2020. Valley Water will decide whether to participate in the project after the environmental review and preliminary planning process.
