The Delta Conveyance Project will move water through a 45-mile underground tunnel, limiting the amount of infrastructure needed at the surface.

Early engineering and design refinements have reduced construction footprints and minimized impacts to Delta communities, roadways, farmland, and sensitive environmental areas.

The Delta Conveyance Authority is advancing engineering and design work earlier than is typical to support the planning and permitting stage of the project.

This approach integrates environmental protections and impact-reduction measures into the project planning from the outset.

The Delta Conveyance Project is being designed with long-term climate resilience in mind.

Facilities will be built to withstand extreme flood events, including future sea level rise, using updated levee criteria standards and the 200-year flood elevation to help safeguard California’s water supply and surrounding communities for generations to come.

Infrastructure connects California’s water system.

From rivers to reservoirs to aqueducts, each part plays a role in delivering reliable water supplies across the state.

The Delta Conveyance Project is a critical upgrade to the State Water Project that will help strengthen these connections and improve water reliability for California.

The Delta Conveyance Project is designed with advanced fish protection technology at its intake facilities.

State-of-the-art fish screens are intended to allow even very small fish to safely swim past the system, helping reduce impacts on aquatic species while modernizing California’s aging water infrastructure.

For more than 60 years, the State Water Project has helped deliver water that supports California communities and agriculture.

The Delta Conveyance Project will modernize that system to improve reliability and resilience against climate change, sea level rise, and seismic threats, helping protect the future of California.

Much of California’s water infrastructure was built decades ago for a very different climate.

Today, changing conditions are putting new pressure on that system.

Projects like the Delta Conveyance Project are designed to modernize critical infrastructure and help improve water reliability for the long term.

California is seeing fewer rainy days, but bigger storms.

That means we need infrastructure that can capture water when it’s available and deliver it when communities, farms, and the environment need it most.

The Delta Conveyance Project is designed to help California make the most of these critical storm events.
