Another legal challenge has been launched against a project by downtown-based water infrastructure company Cadiz Inc. to pump and transport water from its desert aquifer to connect with existing water conveyance systems. This latest lawsuit was filed March 23 against the Bureau of Land Management by the Center for Biological Diversity, Earthjustice and the Sierra Club. It asks the federal court to overturn a December BLM decision to approve the conversion of an idle oil and gas pipeline to carry water from Cadiz’s desert aquifer. Cadiz is not a direct party to the lawsuit but would be impacted by a decision resulting from the suit. The filing marks the third decade in which Cadiz’ water transfer plan has faced legal challenges from environmental groups.
