Desarrollo Habitacional Casa Blanca Wastewater Treatment Plant, Medellín, Veracruz

Desarrollo Habitacional Casa Blanca is a wastewater treatment plant located in Medellín, Veracruz, Mexico. It serves a population of 7,302 and treats wastewater to a secondary level, which is the standard for municipal plants in Mexico under NOM-001-SEMARNAT-1996. The plant has a designed capacity of 864.00 cubic meters per day and discharges 691.20 cubic meters per day of treated effluent. The plant operates under Mexico's federal water quality regulations, which mandate secondary treatment for discharges into water bodies. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the basic requirements for environmental protection. The plant's capacity utilization suggests it is operating below its design capacity, indicating room for future growth. The treated effluent is discharged into a local water body that ultimately drains into the Gulf of Mexico, given the plant's proximity to the coast. The region's aquatic ecosystems, including coastal lagoons and estuaries, benefit from the plant's treatment, which reduces nutrient and pollutant loads. The plant plays a key role in protecting downstream marine habitats from untreated wastewater.

The plant discharges into a local water body that flows into the Gulf of Mexico, a major marine ecosystem. The coastal waters near Veracruz support diverse aquatic life, including fish, crustaceans, and migratory birds. Secondary treatment helps reduce organic pollution and nutrient loading, which is critical for preventing eutrophication in coastal lagoons and estuaries. The plant's location within 10 km of the coast means its effluent directly influences nearshore water quality.
