Roberto Barrios is a municipal wastewater treatment plant located in the town of Roberto Barrios, part of Guasave municipality in Sinaloa, Mexico. The plant serves a small population of 821 residents and operates at a designed capacity of 95.04 m³/day, with an actual discharge volume of 77.76 m³/day. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge into water bodies. For small communities like this, secondary treatment effectively reduces organic matter and suspended solids to meet environmental standards.

The receiving waters ultimately drain into the Gulf of California, a biologically rich marine ecosystem that supports diverse aquatic life, including fisheries and migratory species. Proper treatment helps protect coastal water quality and marine habitats.
Environmental context
The plant discharges into local waterways that flow into the Gulf of California, a semi-enclosed sea known for its high biodiversity and productive fisheries. The region's coastal wetlands and estuaries provide critical nursery habitats for fish and shellfish. Effective wastewater treatment is essential to prevent nutrient loading and contamination that could harm these sensitive marine ecosystems.
