Fraccionamiento INVI Nuevo Mulege Wastewater Treatment Plant, Heroica Mulegé, Baja California Sur

Fraccionamiento INVI Nuevo Mulege is a wastewater treatment plant located in Heroica Mulegé, within the municipality of Mulegé in Baja California Sur, Mexico. The plant serves a population of 1,643 and operates with secondary treatment, discharging 155.52 units of treated wastewater daily. Its designed capacity is 173.66 units, indicating the plant is operating below its full capacity. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids, meeting standard requirements for municipal wastewater. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. Plants of this scale typically require permits from CONAGUA (National Water Commission) to ensure compliance with environmental standards. The plant is located within 10 km of the coast, meaning its treated effluent likely discharges into a coastal water body or a river that flows into the Gulf of California. This proximity to the marine environment necessitates careful management to protect coastal ecosystems, including mangroves and marine life. The plant's operation contributes to safeguarding the local watershed and the broader Gulf of California, a region known for its high biodiversity and ecological significance.

The plant discharges into a coastal environment near the Gulf of California, a semi-enclosed sea with rich marine biodiversity. The treated effluent likely enters a local arroyo or directly into the gulf, affecting nearshore habitats such as mangroves and seagrass beds. These ecosystems support fish nurseries and migratory birds, making proper treatment essential to prevent nutrient loading and protect water quality.
