The New River contains untreated waste and other solid pollutants from Mexico as it flows north through the city of Calexico before emptying out into the Salton Sea. This polluted waterway is a threat to human health and ecosystems and limits economic development. To address this longstanding problem, a project has been conceived that encases the polluted water as it bypasses Calexico, minimizing direct or indirect human contact, as well as an automated trash screen at the border to remove solid waste. The project will also reroute wastewater from the Calexico treatment plant to restore flow in the river channel through the city to improve water quality.
