Overview
BolaNos wastewater treatment plant serves the community of Bolaños, Jalisco, Mexico, with primary treatment for a population of 1,825. It discharges treated wastewater into local water bodies, contributing to the region's water management.
BolaNos is a wastewater treatment plant located in Bolaños, a town in the Región Norte of Jalisco, Mexico. The plant serves a population of 1,825, providing primary treatment to manage municipal wastewater. It is situated inland, more than 10 km from the coast, and plays a role in local sanitation infrastructure. The plant operates with primary treatment, which involves physical processes like sedimentation to remove solids. With a designed capacity of 259.20 cubic meters per day and a discharge volume of 172.80 cubic meters per day, it operates below its full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), primary treatment is acceptable for certain discharge conditions, though secondary treatment is increasingly recommended for environmental protection. The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the Río Grande de Santiago and the Río Lerma-Santiago system. The plant's operation helps protect downstream ecosystems, including rivers and coastal areas, from untreated sewage pollution.
Environmental context
The plant discharges into the Río Grande de Santiago basin, which flows through Jalisco and eventually reaches the Pacific Ocean. This watershed supports diverse aquatic life and is important for regional agriculture and fisheries. The primary treatment reduces suspended solids but may not fully remove nutrients, posing potential risks to downstream water quality if not properly managed.
