Financing approved for Nogales Water and Wastewater System Expansion and Improvement Project

Financing approved for Nogales Water and Wastewater System Expansion and Improvement Project

The city of Nogales, Sonora will receive a US $5.3 million grant provided by the U.S. Environmental Protection Agency (EPA) through the Border Environmental Infrastructure Fund (BEIF), which is administered by the North American Development Bank (NADB). Additionally, the project financing will be complemented with US $5.2 million provided by Mexico. The above was announced during the Public Meeting of the NADB Board of Directors held on November 9 in San Antonio, Texas.

According to Mauro Felix Corrales, Director of the local water utility (Organismo Municipal de Agua Potable, Alcantarillado y Saneamiento de Nogales, OOMAPAS), the US $10.5 million project will expand the city´s services to six marginalized residential areas in southwest Nogales. Subdivisions benefitted include Colosio, Flores Magón, Las Torres, Las Praderas, Primavera, Jardines de la Montaña, and El Rastro. Corrales said this is one of the largest irregular settlement areas in the country and acknowledged that “the project was completed thanks to the collaborative work of the U.S. and Mexican authorities to implement a gradual solution and ultimately remedy the water distribution and wastewater collection situation in the area.”

The project area, which is home to some 4,500 families, receives drinking water by hauled water service and relies on latrines, cesspools, and septic tanks to dispose of wastewater. In addition, as explained by the Director of OOMAPAS, during the city´s two rainy seasons, latrines often overflow and due to the topography of the area, raw wastewater is discharged to the Nogales Wash, which in turn flows to Arizona.

The project includes the construction of more than 35 kilometers of wastewater collection lines, 2,350 drinking water hookups, and 3,506 wastewater household connections during a two-year period. Included in the project scope is also the construction of 2.1 kilometers of the Colector Tecnológico (main collector). The population benefitted will be 16,701 residents who will have 100% of their water and wastewater collection needs properly addressed. The project will help eliminate 41 liters per second of untreated or inadequately treated wastewater discharges.

Mauro Felix Corrales estimates that the project will be completed between 2019 and 2020. Once completed, wastewater from these subdivisions will be conveyed to the Los Alisos Wastewater Treatment Plant located south of Nogales, which was also financed with BEIF funds. The project will enhance the quality of life of area residents and will substantially improve their health by reducing the incidence of gastrointestinal diseases. Mr. Corrales thanked the Bank for the unwavering support it has provided to Nogales through the local utility and the associated Mexican agencies.

Mr. Jose Manuel Mora, a resident of the Colosio subdivision, said in an interview that he had to build a septic tank that cost him $10,000 pesos (some $500 dls.). and has to pay approximately $800 pesos (some $40 dls.) every eight months to have it cleaned. Don Jose also said that he pays close to $800 pesos per week to obtain hauled drinking water from a water truck.

OOMAPAS Technical Director Martin Navarro estimates that the cost of cleaning the septic tanks and buying hauled water represents approximately 30% of the income of these households. Once the connections to the water distribution and wastewater collection systems are installed, the expenses will be less than 10% of the residents´ income. Additionally, these subdivisions may also be eligible for street paving, which will reduce pollution issues.

Navarro added that school located in the Colosio subdivision has to rely on septic tanks, as it has no wastewater collection. “They have a septic tank that is constantly being serviced,” he said. He also mentioned that “gastrointestinal diseases have been identified in both children and adults due to the lack of a sewage system.”

This grand vision project addresses a serious backlog in basic service infrastructure to benefit an extremely impoverished population.
