Sanitation Program of the City of Mexicali - Mexicali,Baja California

Background

Wastewater (WW) discharges from the sewage system of the city of Mexicali had deteriorated the water quality of the New River. Mexican and US Governments coordinated actions within the framework of the International Boundary and Water Commission (IBWC) agreements reached in minutes 264 and 294, to create a Sanitation Program to solve this problem. These minutes included an integral sanitation program for Mexicali, consolidation of planning studies and specified quality conditions for treated municipal water to be discharged to the New River. This Project was referred as Mexicali I Project.
