The region's watershed supports diverse aquatic life and is important for local agriculture and ecosystems. Proper treatment helps protect downstream water quality and public health.
Environmental context
The plant's discharge enters a local stream that flows into the Río Grande de Santiago basin, eventually reaching the Pacific Ocean near Nayarit's coast. This watershed supports freshwater and estuarine habitats, including mangroves and wetlands that provide critical nursery grounds for fish and migratory birds. Effective secondary treatment reduces nutrient and pathogen loads, safeguarding these downstream ecosystems.
