The Negombo Lagoon cleanup project in Sri Lanka was recently completed by using a multipurpose Watermaster amphibious dredging machine. 

The Negombo Lagoon suffers from heavy siltation and the presence of urban debris, making big trouble for the fishing and sightseeing boats to enter the certain parts of the lagoon.

Watermaster’s Urban Dredging Concept was utilized to solve the problem.

The company’s patented Cutting Knife System for debris enabled Watermaster to pump soils containing a significant amount of plastics and other urban trash and thus dredge in areas where only excavation work was previously possible.

During the cleanup work, Watermaster multipurpose dredger removed 12,000m³ of silt and urban trash from the lagoon.
