Sanitation Plan for the Santiago Basin (Chile): improving wastewater treatment coverage from 3% in 1999 to 100% in 2012
An important step in the process of modernizing the Chilean sanitation sector is represented in the plan of sanitation of the Santiago water basin, consisting of an ambitious project headed by Aguas Andinas, a company partly owned by AGBAR since the privatization in 1999. The plan was conceived as a necessity on a national level to contribute to improve, in a significant way, the quality of life for more than 6 million inhabitants and guarantee a state of environmental sustainability.
The solution included the construction of more than 20 waste water treatment plants and several collectors. This plan and the continued strategy of investment of Aguas Andinas since 2000 has allowed to move progressively to increase the coverage of wastewater treatment from 3% in the year 1999 to 89% in 2010. The coverage will reach 100% in 2012.
