Atotonilco Wastewater Treatment Plant

In partnership with other companies such as Acciona Agua Desarrollo y Construcciones Urbanas, Atletec e Impulsora de Desarrollo y Empleo de Latinoamérica, we formed a consortium called Aguas Tratadas del Valle de México, which had the concession to design, build, operate the plant for 22 years and transfer it the federal government at the end of the contract.

This is the largest treatment wastewater plant in Latin America and one of the largest in the world; the treated waters it produces are currently used in agriculture without any additional purification process necessary. For most of the year, the wastewater treatment is performed by a conventional series of processes, and in the rainy season, a chemical process. Furthermore, to enhance the sustainability of its operation, the energy content of the sludge is used and the methane gas is converted into electrical energy and thus, making the plant self-sufficient.
