Environmental context
The plant's discharge enters local streams within the Armería River basin, which flows westward to the Pacific Ocean near the port of Manzanillo. This coastal watershed supports mangrove ecosystems and estuarine habitats that are important for fish and bird species. Effective secondary treatment reduces nutrient and organic loads, helping to prevent eutrophication and maintain water quality in downstream environments.
