Colombia - Embalse del Muña dispute

The Embalse del Muña is a water reservoir serving a pumping system that draws water from the Bogotá river downstream of the city in the department of Cundinamarca. It is owned by the Emgesa SA Group and used for the production of energy.

In 2001, the inhabitants of Sibaté (a town near the lake) filed a “class action” against other national, provincial and municipal public bodies, as well as private entities operating near the banks of the Bogotá river, for damages of 1,130 million euro resulting from the contamination of the El Muña reservoir. The claims were merged into a single action due to their homogenous interests. In response to these claims, Emgesa SA has declared that it is not liable for the alleged events, since the basin receives already contaminated waters. Emgesa SA also requested the involvement in the proceedings of numerous public and private bodies that discharge into the Bogotá river or which, for various reasons, are responsible for environmental management of the riverbed. On appeal, the Council of State fully confirmed the decision of the Administrative Court of Cundinamarca, which among other things had denied Emgesa’s request to extend the suit to various third parties involved. An administrative complaint was filed against this decision, followed by an appeal.

In November 2017, the Administrative Court of Cundinamarca revoked the decision of the lower court with a ruling in favor of Emgesa SA. Several companies have filed a new appeal and proceedings are pending.
