A removal sediment by using Siphon technique in water reservoir

Water is the natural resources uses for multi-functional for human purpose. Water reservoir the main structure to supply and distribute water to the communities. According ICOLD world water storage decrease cause of sedimentation. Sedimentation also can damage the structure reservoir and dam. This study was develop to control sedimentation activities by remove away sediment before deposition occur. Siphon model was fabricated in scale 1:40 using 3D printing. Retention wall with dimension 0.49m x 0.46m was install using silicone inside the flume. Two trapping filter with dimension 0.49m x 0.46m had been install using silicone inside the flume in front of siphon outlet to protect the pump from damage. The siphon operation using different water level 0.41m to 0.40m, 0.40m to 0.39m, 0.39m to 0.38m and 0.38m to 0.37m. Sandy silt was use for sediment materials. The sandy silt fill into the rectangular made plywood block with two bar iron use with dimension 1m x 0.49m x 0.08m to block sediment distribute out from siphon inlet when the flume fill in with the water. The pressure manometer tube had been located at siphon in let. The ideal water level for highest siphon performance on water level 0.40m to 0.39m with the highest amount sediment suction 1185g. The lowest pressure 470pa. Type of topography contour at suction inlet of siphon had been observe and identified.
