Jalmolonga 1 Wastewater Treatment Plant, Xalmolonco, Estado de Mexico

Jalmolonga 1 is a municipal wastewater treatment plant located in the community of La Soledad, Acatzingo, in Xalmolonco, Malinalco, Estado de Mexico, Mexico. The plant serves a small population of 703 people, reflecting its role in a rural or semi-urban setting within the central highlands of Mexico. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 216 cubic meters per day and a current discharge volume of 66.53 cubic meters per day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharges to water bodies, and the plant's performance aligns with national standards. The treated effluent is discharged into local watercourses that ultimately drain into the Balsas River basin, one of Mexico's major river systems. The Balsas River flows southwest to the Pacific Ocean, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant's operation helps protect downstream water quality in this ecologically important basin.

The plant discharges into the Balsas River basin, which drains into the Pacific Ocean via the Balsas River. This basin supports a variety of freshwater habitats and is important for regional biodiversity, including endemic fish species. The secondary treatment provided by the plant reduces organic pollution, helping to maintain water quality in downstream rivers and reservoirs that are used for irrigation and domestic supply.
