Table of ContentsBackground - Learn more about the Nogales International Wastewater Treatment Plant BackgroundThe City of Nogales, Arizona is located in Santa Cruz County and is adjacent to the U.S.-Mexico Border. During the 2000 U.S. census, the city's population was estimated to be approximately 20,000.
Through the decades, the plant was upgraded, enlarged and enhanced in response to population and flows. Today, the population served exceeds 350,000. Once again, it is time to respond to regional wastewater treatment needs. The plant is currently located at 865 Rio Rico Industrial Park in Rio Rico, AZ 85648. Over the past years a work group comprised of representatives from the U. S. International Boundary and Water Commission (USIBWC), the U.S. Environmental Protection Agency, Region 9, the Border Environment Cooperation Commission (BECC), The Arizona Department of Environmental Quality (ADEQ), the University of Arizona (UofA), the North American Development Bank, and the City of Nogales have been meeting regularly to address the regional demands for wastewater treatment. Regulations applicable to the plant require that the effluent quality be greatly enhanced, prompting a change in treatment process. The City has decided to construct the project under a Design-Build delivery method. Watch this page for progress.

The analysis, performed by CDM, evaluated the feasibility and estimated costs of a minimum of six treatment technology alternatives capable of bringing the NIWTP into compliance with all applicable effluent discharge standards and limits. [read final report] In September 2005, Camp Dresser and McKee Inc. (CDM) completed the Evaluation of Alternatives for Upgrading the Nogales International Wastewater Treatment Plant (NIWTP) for the City of Nogales. Six treatment alternatives were evaluated as part of this study, of which the following four were deemed feasible. The Nogales Technical Committee (NTC) identified Alternative 2 – New MLE as the preferred alternative, and directed CDM to identify, if possible, potential reductions to the cost estimates for this alternative, while providing a plant capable of meeting all regulations at a design flow of 14-MGD. Areas for potential cost reductions were identified and evaluated.

Since its conception in 1943, the Nogales International Wastewater Treatment Plant (NIWWTP) has approached the treatment and disposal of wastewater as a regional issue. The NIWWTP provides service to Nogales, Arizona, Nogales, Sonora, and the surrounding areas of Santa Cruz County, Arizona. The original plant was designed to support a population of 20,000.
