Cordeleros de Chuburna Wastewater Treatment Plant, Mérida, Yucatán

Cordeleros de Chuburna is a municipal wastewater treatment plant located in Mérida, the capital of Yucatán, Mexico. The facility serves a small population of 913 residents in the Distrito 1 area, operating at a designed capacity of 86.40 cubic meters per day. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under Mexico's national water regulations, which are enforced by the National Water Commission (CONAGUA). For small communities like this, secondary treatment is the standard requirement to protect public health and the environment. The plant's discharge volume matches its designed capacity, indicating consistent operation. The treated effluent is discharged into the local hydrological system, which ultimately drains into the Gulf of Mexico via the Yucatán Peninsula's karstic aquifer and coastal wetlands. The region's porous limestone geology makes groundwater particularly vulnerable to contamination, so proper treatment is essential for protecting both drinking water sources and the sensitive coastal ecosystems of the northern Yucatán coast.

The plant discharges into the Yucatán Peninsula's karstic aquifer system, which feeds coastal wetlands and the Gulf of Mexico. This region is ecologically sensitive due to its porous limestone geology, where pollutants can rapidly reach groundwater and marine environments. The nearby coastal zone supports mangroves and seagrass beds that provide critical habitat for fish, sea turtles, and migratory birds.
