The Economy of the State Water Project Brochure and Report from DWR

The State Water Project (SWP) is among the world's most extensive water conveyance projects, featuring a 705-mile-long network of dams, reservoirs, hydroelectric facilities, pumping plants, and canals. The State Water Project plays a key role in the state’s economy. It supplies over 27 million Californians, a majority of the state’s population, along with commercial and industrial customers, including in the technology and manufacturing sectors, that account for a majority of the state’s economic activity. Project deliveries also supply water to the agricultural sector, supporting the cultivation of fruits, vegetables, and nuts, particularly in the Central Valley, the nation’s most productive agricultural region. This reliable water source not only ensures the livelihood of residents, businesses, and farmers but also contributes significantly to the state’s economy through technology, manufacturing, and agricultural exports.

This report consolidates publicly available data from the California Department of Water Resources (DWR) and other agencies to provide policymakers with a comprehensive overview of the economy that is supported by the State Water Project. The aim is to present this information in a concise format to facilitate wellinformed decision-making regarding the project. The information in this report covers patterns of water use in the State Water Project service area, the size of the urban and agricultural economies served by the State Water Project, the role of the State Water Project in serving underrepresented communities, and how the costs of State Water Project water deliveries compare to the costs of developing alternative water supplies.
