Spain's Grupo Acciona said Tuesday it received a contract to design and build the first phase of the El Caracol residential water treatment plant in Mexico City.

The Mexican National Water Commission, or Conagua, awarded the contract to a consortium in which Acciona has an interest.

The contract, worth 764 million pesos ($59.5 million), also covers operation and maintenance of the plant for 23 years.

Acciona is involved in developing and managing infrastructure, renewable energy, water and other projects.

The El Caracol plant, the second in Mexico City, complements the Atotonilco plant, which will process 60 percent of the wastewater in the Valley of Mexico and is being built by Acciona.

The plant will clean 2,000 liters (528 gallons) per second of water that will be used to irrigate 6,000 hectares (14,814 acres) of crops in Texcoco and Atenco, two cities located in the Mexico City metro area, and help with the environmental restoration of more than 2,000 hectares (14,814 acres) of the former Lake Texcoco.

The winning consortium, in which Acciona has a 50 percent stake, also includes Mexico's Promotora del Desarrollo de America Latina, Carso Infraestructura and Operadora CICSA.

The federal government is providing 40 percent of the financing for the project via the National Infrastructure Fund, or FONADIN, with the rest of the money being provided by the consortium, which arranged for financing from Mexico's National Public Works and Services Bank, or Banobras.

The project bolsters Acciona's presence in Latin America, where the company's water unit recently won a $45.6 million contract to design, build and operate the Los Tajos plant in San Jose, Costa Rica. EFE
