Chilean water utility Aguas Andinas has uncovered well-preserved mastodon remains while expanding its Mapocho-El Trebal wastewater treatment plant in capital Santiago.
Chilean paleontologists are working at the Mapocho plant, which is managed by French group Suez Environnement. Work at the plant will continue alongside the research, Suez said in a release.
Work is due to wrap up this year on the US$420mn Mapocho plant, which will allow Aguas Andinas to treat 100% of Santiago's wastewater. The company currently treats 86% of wastewater produced in the metropolitan region.
