New River Improvement Project

New River Improvement Project

The New River flows north from Mexico into the United States where it crosses the City of Calexico, California. The State of California's Clean Water Act Section 303(d) lists the New River as impaired by numerous constituents, and is a State of California priority for cleanup purposes. The proposed project consists of three primary components: (1) construction of a trash screen at the International Boundary with Mexico; (2) divert and encase the river from a point downstream of the International Boundary to a point downstream of the eastern boundary of Calexico in order to bypass the populated southern area of the City; and (3) a pump-back system to take treated wastewater from the existing City of Calexico Wastewater Treatment Plant and discharge it into the New River channel at a point near the proposed river diversion and encasement structure.
