Nogales, Sonora, Mexico

Expansion of the Water and Wastewater Systems to the Southwest Area of Nogales, Sonora

Status: Under construction


The purpose of the Project is to increase access to sustainable potable water service and eliminate exposure to untreated or inadequately treated wastewater discharges by providing first-time DW and WWC services to residents in the Nogales’ Southwest Colonias, contributing to the reduction of water pollution and risk of waterborne diseases; as well as reducing health risks associated with hauled water service.


The proposed project includes the expansion of the municipality’s drinking water (DW) distribution and wastewater collection (WWC) system infrastructure to the following residential areas (“Colonias”) in Southwest Nogales, Sonora: Flores Magón, Las Torres, Luis D. Colosio, El Rastro, Las Primaveras, and Jardines de la Montaña (the “Project”).


The environmental and human health outcomes anticipated for the Project include:

 Provide access to DW services for 2,350 homes.

 Provide access to wastewater collection services to 3,506 homes including the installation of household WW connections for 100% of the Project area.

 Eliminate untreated or inadequately treated wastewater discharges of approximately 0.93 million gallons per day (mgd).
