The ecological condition of urban water bodies is rapidly deteriorating. Pollution of reservoirs occurs due to natural processes and anthropogenic human influence. Violation of the functioning of the ecosystem of the reservoir leads to a deterioration of water exchange, water bloom, reduced transparency, the appearance of unpleasant odors, burrowing and bumping. In our time, dewatering of bottom sediments is carried out by hardware methods (using centrifuges and press filters) or by natural drying on bulk charts. The hardware dehydration method allows you to get material that is suitable for transportation on the output. But the devices themselves are sensitive to mechanical inclusions contained in the pulp, are prone to abrasive wear and, as a consequence, frequent downtime. Dehydration on maps requires the allocation of large areas that are not possible in close urban development. In addition, it is impossible to dewater the bottom sediments in the short-term maps on the maps. Therefore, for urban development, it is necessary to look for the best alternate technology of dewatering bottom sediments. A decent substitute for these methods of dehydration is Geopool and Geotube technology. Their application does not require significant alienation of coastal areas under the works and does not pollute the environment with associated products of production.
