Delta Conveyance Project


The Delta Conveyance Project is California’s proposed plan to improve the infrastructure that carries water through the Sacramento-San Joaquin Delta. The project would feature a single tunnel with two intakes on the Sacramento River near the City of Sacramento that would allow water to be carried underneath the Delta to existing facilities in the south. Currently, the Delta water system is outdated and at risk of failing due to future events such as climate change, sea level rise, earthquakes, and flooding. The proposed project aims to modernize this system and protect California’s water supply from these risks. The Delta Conveyance Project also aims to provide greater flexibility to 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. After the environmental review and preliminary planning process, which is projected to be complete in 2024, Valley Water will decide whether to participate in the project.
