La Coronilla Wastewater Treatment Plant, Ameca, Jalisco, Mexico

La Coronilla is a wastewater treatment plant located in Ameca, within the Valles region of Jalisco, Mexico. It serves a small population of 913 residents, providing secondary treatment to meet local sanitation needs. The plant has a designed capacity of 86.40 cubic meters per day, matching its current discharge volume. As a secondary treatment facility, La Coronilla employs biological processes to reduce organic matter and suspended solids. In Mexico, wastewater treatment plants are regulated under the National Water Law and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. For small communities like Ameca, secondary treatment is typical to protect water quality in receiving water bodies. The plant's treated effluent is discharged into local waterways that eventually drain into the Pacific Ocean via the Ameca River basin. This region supports diverse aquatic life and agricultural activities downstream. Proper treatment helps prevent eutrophication and maintains the ecological health of the river system.

The treated effluent from La Coronilla flows into the Ameca River, which runs through Jalisco and ultimately reaches the Pacific Ocean. This watershed supports agricultural irrigation and freshwater habitats. The plant's secondary treatment reduces organic pollutants, protecting downstream water quality and aquatic ecosystems from nutrient enrichment.
