Sediments in lakes and reservoirs mainly consist out of clay, silt and varied sizes of sand. Therefore it is very important to dredge and clean reservoirs, lakes or dams regularly, to restore them to their full capacities and prevent the sediments from reaching the turbines or outlet. Sometimes they can even cause severe wear damage to the turbines if the sediments reach the level of the water outlets. Sediments diminish the total water reserve capacity of the plant. Throughout the years hydro-power dams, reservoir and freshwater lakes retain and accumulate quantities of sandy deposits behind or in them. They can for example be part of a hydropower installation, used for agricultural purposes or for fresh water storage for drinking water. Herewith ensuring a reliable intake of water for your industrial process all year round.Ī variety of dams are constructed in rivers for different reasons. Proper and regular maintenance is needed to keep the basins clean and the capacity at its maximum.ĭredging effective tool to keep these intake canals open and the sand traps cleaned. That limits the cooling capacity of the plants. At these sand traps, the sediments pile up through the years. Often these water intakes are equipped with sand traps to avoid sand entering the industrial plant. These water intakes are commonly connected to lakes, rivers, canals or the open sea and can get blocked by sediments. Large industrial plants like petrochemical plants, power plants and desalination plants use large water intake channels for cooling water or for other purposes.
