The facility serves a population of about 117,278 residents, placing it in the medium-to-large agglomeration category for the region. Its designed capacity is 1. As a Mexican wastewater facility, PTAR Oriente operates under the framework of the Ley de Aguas Nacionales (National Water Law) and is subject to standards set by CONAGUA (Comisión Nacional del Agua). For plants serving populations over 100,000, Mexican regulations typically require secondary treatment or higher to protect water quality in receiving bodies. The regulatory context implies compliance with national discharge norms. The treated effluent from PTAR Oriente likely discharges into a local watercourse that drains into the Gulf of Mexico via the Soto La Marina River basin. This region supports diverse aquatic life and is important for downstream ecosystems. The plant's operation helps reduce pollutant loads to the watershed, contributing to the environmental health of the area.

PTAR Oriente is situated in the Soto La Marina River basin, which flows eastward into the Gulf of Mexico. The receiving water body, likely a tributary of the Soto La Marina, supports freshwater and estuarine habitats. Downstream, the river meets the Gulf, a critical marine environment for fisheries and migratory species. The plant's discharge management is essential for maintaining water quality in this ecologically sensitive coastal region.
