El Carrizal Segundo Wastewater Treatment Plant, El Carrizal Dos, Tamaulipas

El Carrizal Segundo is a municipal wastewater treatment plant located in El Carrizal Dos, within the municipality of Aldama, Tamaulipas, Mexico. The plant serves a small population of 456 residents, reflecting its role in a rural or peri-urban community. It operates under Mexico's national water regulations, which require secondary treatment for discharges into water bodies. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids. With a designed capacity of 50.11 units and a current discharge volume of 43.20 units, the facility operates below its maximum capacity, indicating room for future growth. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into local watercourses that drain into the Gulf of Mexico, contributing to the health of downstream aquatic ecosystems. The plant's operation helps protect water quality in the region, supporting both environmental and public health objectives in the Tamaulipas lowlands.

The plant discharges treated wastewater into local streams that flow toward the Gulf of Mexico, a major marine ecosystem. The region's watershed supports diverse aquatic life and is important for fisheries. By providing secondary treatment, the plant reduces nutrient and pollutant loads, helping to prevent eutrophication and maintain water quality in downstream coastal areas.
