Wednesday, December 7, 2011

Chilean water utility Aguas Andinas, which serves the metropolitan region including capital Santiago, aims to start full operations of its Mapocho wastewater treatment plant in the second quarter next year, according to Aguas Andinas chairman Felipe Larraín.

The US$300mn project is currently around 80% complete.

"In a few more months, our capital and country will be able to exhibit a new world class indicator: the effective remediation of all urban wastewater, placing us in the top ten most developed nations for environmental care and responsibility," the executive said at an event held by Aguas Andinas in the Chilean capital.

The plant, located in the city's Padre Hurtado municipality where the utility's El Trebal wastewater treatment plant was also built, will allow Aguas Andinas to treat 100% of Santiago's wastewater. As of October last year, the company currently treated 86% of wastewater in the region.

The initiative is the final stage of Aguas Andinas' sanitation plan for the Santiago basin, which began in 2000 and has required a total investment of over US$1bn, according to Larraín.

Aguas Andinas, Chile's largest water utility, is controlled by Spain's Agbar, which is owned by French group Suez Environnement.
