Access to Drinking Water: Water Treatment Project in Colombia

Good health and well-being
Clean water and sanitation

Department of Antioquia, Colombia: addressing the need for a functional drinking water system at the Jorge Eliecer Gaitán school in the community of Los Cargueros. This ensures access to clean drinking water for students and staff and improves the educational conditions.

(Last update: August 2023)

Suministros Agromineros S.A.S., through Mineros S.A., and the Swiss Better Gold Association have jointly supported a water treatment project in the community of Los Cargueros. With a focus on formalisation, Mineros S.A. works with small- and medium-scale mining operations (dredges) on their concession, a successful example of collaboration between large-scale and small-scale mining in order to develop sustainable initiatives to create positive impact. The Swiss Better Gold premium generated by the dredges contributes to social and environmental projects in the areas where these dredges operate. To improve access to clean drinking water, the Jorge Eliecer Gaitán school was provided with a reliable supply of clean drinking water.

The Water Treatment Project benefits 460 students and staff members. By implementing a comprehensive water treatment system and develop infrastructure, education and the overall well-being of the community are significantly improved. 

Date of project completion:

The installation of a comprehensive water system and the improvement of the sanitary infrastructure were achieved in April 2023.
