Parque del Arbol Wastewater Treatment Plant, León, Guanajuato, Mexico

Parque del Arbol is a secondary-level wastewater treatment plant located in León, Guanajuato, Mexico. Serving a population of 2,145, it is part of the municipal wastewater infrastructure for the San Nicolas De Gonzalez area. The plant treats an average daily flow of 203.04 units against a designed capacity of 302.40 units, indicating a utilization rate of approximately 67%. As a secondary treatment facility, Parque del Arbol provides biological treatment to remove organic matter and suspended solids. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is the standard for municipal wastewater before discharge into water bodies. The plant's capacity and flow data suggest it operates within its design parameters, with room for future growth. The treated effluent from Parque del Arbol ultimately drains into the Lerma River basin, which flows through Guanajuato and into Lake Chapala, Mexico's largest freshwater lake. This watershed supports agricultural irrigation, fisheries, and biodiversity. Proper treatment at this plant helps protect downstream water quality and aquatic ecosystems in the Lerma-Chapala basin.

Parque del Arbol discharges into the Lerma River basin, which flows into Lake Chapala, a critical freshwater resource for the region. The Lerma-Chapala watershed supports diverse aquatic life and provides water for agriculture and human consumption. Secondary treatment at this plant reduces organic pollutants and suspended solids, mitigating eutrophication risks in downstream water bodies.
