Boca de Pascuales Wastewater Treatment Plant, Tecomán, Colima, Mexico

Boca de Pascuales is a wastewater treatment plant located in Tecomán, Colima, Mexico, along the Carretera Tecomán - Boca de Pascuales. The plant serves a small population of 317 people and operates with a designed capacity of 345.60 cubic meters per day, currently treating 172.80 cubic meters daily. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants before discharge. The plant is situated within 10 kilometers of the Pacific coast, making its discharge location environmentally sensitive. Under Mexico's national water regulations (Ley de Aguas Nacionales), wastewater treatment plants are required to meet discharge standards set by CONAGUA, and secondary treatment is appropriate for this scale of agglomeration. The treated effluent likely drains into local streams or directly into the Pacific Ocean, contributing to the coastal ecosystem of the Colima region. The plant plays a role in protecting the marine environment by reducing pollutant loads from the small community it serves.

The plant discharges near the Pacific coast in Colima, Mexico, a region known for its diverse marine ecosystems and coastal lagoons. The treated wastewater likely enters local drainage channels that flow into the ocean, affecting nearshore water quality and habitats such as mangroves and estuaries. These coastal areas support fish nurseries and migratory bird populations, making proper treatment essential for ecological health.
