El Bethi Wastewater Treatment Plant, El Bethí, Hidalgo, Mexico

El Bethi is a wastewater treatment plant located in the small community of El Bethí, within the municipality of Chilcuautla, Hidalgo, Mexico. The plant serves a population of about 3,195 residents, reflecting its role in managing domestic wastewater for this rural area. The facility provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 302.40 cubic meters per day and a similar discharge volume, the plant operates at full capacity. In Mexico, wastewater treatment plants of this scale are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent is likely discharged into a local watercourse that drains into the Tula River basin, eventually reaching the Gulf of Mexico. The plant helps protect local water quality and supports the ecological health of the region's surface waters.

The plant's treated wastewater likely enters a tributary of the Tula River, which flows through the Mezquital Valley and eventually into the Pánuco River and the Gulf of Mexico. This region is semi-arid, and water resources are critical for agriculture and domestic use. The plant's secondary treatment reduces organic pollution, helping to maintain water quality in downstream ecosystems that support aquatic life and local communities.
