• Restore capacity

    Dam dredging and cleaning restores the dams, reservoirs or lakes to their full capacities.

  • Prevent turbine damage

    Sediments can cause severe wear damage to the turbines if they reach the level of the water outlets. Therefore dam dredging is crucial.

Reservoir, lake & dam dredging

Reservoir, lake and dam dredging is a type of maintenance dredging, which involves silt removal. A variety of dams are constructed in rivers for different reasons. For example, they can be a part of a hydro power installation, used for agricultural purposes or for fresh water storage for drinking water. Throughout the years hydro-power dams, reservoirs and freshwater lakes retain and accumulate quantities of sandy deposits in or behind them. As a result, sediments diminish the total water reserve capacity of the plant. This is called reservoir sedimentation  Sometimes, sediments can even cause severe wear damage to the turbines if the sediments reach the level of the water outlets.

Therefore, maintenance dredging (or dam sediment removal) is very important. In other words, reservoirs, lakes and dams must be dredged regularly, to restore them to their full capacities and prevent the sediments from reaching the turbines or outlet.

Sediments in lakes and reservoirs mainly consist of clay, silt and varied sizes of sand. It can also contain chemical precipitates, organic debris and a lot of times combinations of these. Our dredgers are ideal for dam dredging and silt removal from these reservoirs and lakes.
