Business Description and Basis of Presentation [Text Block]	NOTE 1 – DESCRIPTION OF BUSINESS Cadiz Inc. (“Cadiz or the “Company”) is a water solutions provider dedicated to delivering clean, reliable, and affordable water for people through a variety of innovative water supply, storage, conveyance and treatment projects. The Company is advancing human access to clean water with its unique combination of land, water, infrastructure and technology assets, cutting-edge innovation, and industry-leading standards of environmental stewardship. The Company owns approximately 46,000 acres of land with access to high-quality, naturally-recharging groundwater resources in three areas of Southern California’s Mojave Desert – the Cadiz Valley (35,000 acres), Danby Dry Lake (2,000 acres), and the Piute Valley (9,000 acres) (“Cadiz Property”). The Company’s land holdings with vested water rights were primarily assembled by its founders in the early 1980s, relying on NASA imagery that identified a unique desert aquifer system at the base of a vast Southern California watershed. Since its founding in 1983, the Company has developed its unique land assets in California for sustainable farming and groundwater management, and in recent years, has invested in wellfield and pipeline infrastructure as well as groundwater treatment technology that will enable us to play a critical role in serving the needs of people and communities that lack access to clean, reliable and affordable water. The Company’s unique supply, storage and pipeline assets are located in a remote area of eastern San Bernardino County that sits at the crossroads of major highway, rail, energy, and water infrastructure between California’s primary water supply systems, the Colorado River Basin and the State Water Project. As a result, our Cadiz Water Conservation and Storage Project is uniquely positioned to assist public water agencies in storing and managing unpredictable water supplies and provide reliable, affordable water supplies to chronically underserved areas of California.
