Emilio Carranza Wastewater Treatment Plant, Veracruz, Mexico

The Emilio Carranza wastewater treatment plant is located in the town of Emilio Carranza, within the municipality of Vega de Alatorre, Veracruz, Mexico. The plant serves a population of approximately 7,302 residents, classifying it as a small to medium-sized facility under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard level required by Mexican environmental law (NOM-001-SEMARNAT) for municipal wastewater before discharge. Although the designed capacity is 3,421.44 m³/day, the actual discharge volume is 691.20 m³/day, indicating the plant operates well below its capacity. The plant is situated within 10 km of the Gulf of Mexico coast, making its discharge potentially influential on coastal water quality. The treated effluent likely flows into local streams or directly into the Gulf, affecting nearshore marine ecosystems. The region's tropical climate and proximity to the coast mean the plant plays a role in protecting both freshwater and marine environments from nutrient pollution and pathogens.

The plant is located near the Gulf of Mexico, a major marine ecosystem that supports diverse aquatic life including fish, crustaceans, and sea turtles. The treated wastewater likely discharges into small coastal streams or directly into the Gulf, contributing to the nutrient load in nearshore waters. The region's watershed drains from the Sierra Madre Oriental to the coast, and the plant's effluent can affect local water quality and marine habitats, particularly in the context of nutrient-sensitive coastal zones.
