In Acolman (State of Mexico), a new nature-based wastewater treatment plant is under construction for the Los Héroes Acolman residential development. The system follows the proven model used in our projects in Rayón, Mexicali and Cihuatlán: robust primary treatment, natural sludge humification, and a vertical-flow constructed wetland, followed by a naturally designed polishing pond providing substantial ecological added value.
At Aquatech Mexico 2025, held September 2–4 at Centro Banamex, Mexico City, J&S Engineers will present innovative water reuse solutions. Our Constructed Wetlands (CW) offer eco-friendly wastewater treatment, enabling irrigation for greenery, parks, and buildings while reducing pollutant discharge into rivers. These systems lower freshwater use, energy costs, and wastewater fees, promoting sustainability. Projects like Cihuatlán and Mexicali demonstrate high purification with minimal energy, supporting local ecosystems. Our work enhances quality of life for communities, flora, and fauna, making CWs a cornerstone of sustainable urban water management.
We continue our work in the field of nature-based wastewater treatment in Mexico. Our third large-scale project is currently being implemented in Rayón, involving the rehabilitation and expansion of an existing wastewater treatment plant.
