The plant is situated in the Villa Galaxia neighborhood and is part of the municipal wastewater infrastructure for the city of Mazatlán, a major coastal city on the Pacific Ocean. As a medium-sized agglomeration, the plant is expected to comply with Mexican Official Standards (NOM-001-SEMARNAT) for wastewater discharge, which set limits on pollutants based on the receiving water body. The plant discharges into the Pacific Ocean via local drainage, contributing to the coastal water quality of the Gulf of California. The region supports diverse marine life, including important fisheries and migratory species, making effective treatment essential for environmental protection.

The plant's effluent ultimately reaches the Pacific Ocean near Mazatlán, a coastal city on the Gulf of California. This marine environment supports diverse aquatic life, including commercially important fish species and migratory birds. The Gulf of California is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient loading and pollution from coastal discharges.
