On 13th June 2025, a large-scale river cleaning campaign was organized. Over 85 volunteers from Dantak, including the Chief Engineer himself, joined hands with the River Cleaning Desuups, forming a team of over 100 volunteers.
Together, they cleaned the stretch of the Wangchu River between Depsizam and Ramazam, collecting two full truckloads of black plastic waste once again originating from the Babesa sewage treatment plant.
