Unidad Habitacional Pemex is a wastewater treatment plant located in Salina Cruz, Oaxaca, Mexico, serving a population of around 12,778 residents. The plant is situated near the Pacific coast, within 50 km of the shoreline, and operates under Mexico's national water regulations. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit). As a facility serving a medium-sized agglomeration, it is expected to comply with Mexican Official Standards (NOM-001-SEMARNAT-1996) for wastewater discharge, which set limits on pollutants based on receiving water body type. The plant discharges into the local watershed, which ultimately drains into the Pacific Ocean. The coastal environment supports diverse marine life and is important for local fisheries and tourism. Proper treatment is essential to protect water quality and ecosystem health in this sensitive coastal region.
Environmental context
The plant's discharge likely enters the Pacific Ocean via local streams or the nearby Laguna Superior, a coastal lagoon system. This area supports mangrove forests and serves as a nursery for fish and crustaceans, making it ecologically sensitive. Downstream, the waters contribute to the broader Gulf of Tehuantepec ecosystem, which hosts diverse marine species and is an important fishing ground.
