DCA was formed, under DWR's oversight, to design and implement a safe, reliable conveyance system

09/21/2026

The Delta Conveyance Project is a state-of-the-art upgrade to the State Water Project, which serves 27 million Californians.

With two new North Delta intakes and a 45-mile underground tunnel, the DCP will improve flexibility and reliability as California faces sea-level rise, earthquake risk and changing hydrology.

The Delta Conveyance Project does not create new water rights. It modernizes how existing State Water Project supplies move through the Delta using infrastructure designed for California’s climate reality.

Engineering refinements are improving the Delta Conveyance Project’s constructability, strengthening cost-confidence, and supporting informed decision-making.

Based on early evaluations, project refinements will save $1.25 billion and 1,500 days of projected construction schedules.

Designed to maximize high flow conditions, the Delta Conveyance Project will improve California’s ability to capture and move water during wet periods and atmospheric rivers.

By adding operational flexibility to the existing system the project will help California better manage increasingly variable conditions.

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.

Designed with local communities in mind, the Bethany Complex incorporates measures to reduce construction impacts including dedicated haul roads, limited nighttime work, on-site concrete batching to reduce truck trips, and a compact footprint with most facilities located below ground.

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.
