The plant discharges into the local drainage network within the Papaloapan River basin, which flows into the Gulf of Mexico. This coastal watershed supports diverse aquatic habitats, including mangroves and estuaries, and is important for fisheries and biodiversity. Effective secondary treatment reduces organic load and suspended solids, helping to maintain water quality in downstream ecosystems.
