Unidad Habitacional Central Progreso Wastewater Treatment Plant, Paso del Macho, Veracruz

Unidad Habitacional Central Progreso is a wastewater treatment plant located in Paso del Macho, Veracruz, Mexico. The facility serves a population of 4,564 and operates with secondary treatment, a standard level for communities of this size in Mexico. The plant has a designed capacity of 691.20 m³/day and currently discharges 432.00 m³/day of treated wastewater. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids, meeting typical national discharge standards for inland plants. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Jamapa River basin. The plant plays a key role in protecting downstream ecosystems and water quality in the region, supporting both agricultural and ecological water uses.

The plant's discharge contributes to the Jamapa River basin, which flows into the Gulf of Mexico near the port of Veracruz. This coastal region supports diverse aquatic life and is important for local fisheries. The secondary treatment helps reduce nutrient loading and organic pollution, mitigating eutrophication risks in downstream waters.
