It is used to control the water level in the system. In the water retention structures, the water level is controlled by another movable pipe that is moved up and down and which is in fixed vertical pipe. Telescopic valves operate according to the siphon system to transfer the water. Since water transportation is performed in the water surface, it does not affect the sediments at the bottom. Therefore, it is also used in sludge removal structures. In addition, they are used to determine the outlet level of the water in the sedimentation tank since it allows precise adjustment while determining the water level.
