Punta Chica Wastewater Treatment Plant, Manzanillo, Colima, Mexico

Punta Chica is a wastewater treatment plant located in Manzanillo, Colima, Mexico, serving a population of approximately 10,746 residents. The facility is situated in the historic center of Manzanillo, a major port city on the Pacific coast. As a municipal plant, it plays a key role in managing wastewater from this urban area. The plant operates within Mexico's regulatory framework for wastewater management, which includes the Federal Law of Waters and the National Water Commission (CONAGUA) standards. For a plant serving around 10,000 people, secondary treatment is typically required to reduce organic pollutants before discharge. The plant's location within 50 km of the Pacific Ocean means its treated effluent likely drains into the coastal watershed, eventually reaching the Pacific. This proximity to the coast underscores the importance of effective treatment to protect marine ecosystems and coastal water quality in the Manzanillo Bay area.

The plant's discharge likely flows into the Pacific Ocean via local streams or the Manzanillo Bay. The coastal waters support diverse marine life, including fish and crustaceans, and are important for local fisheries. Proper treatment is essential to prevent nutrient pollution and protect the ecological health of this coastal environment.
