The equipment can guide the water flow and help collect the lighter or smaller drifting materials on the river. This can save the time and cost of salvaging and removing the waste by manpower. First, fix the interceptor onto the riverbank where the water flow is gentle, turn on the pumping motor, observe the direction of the water flow, and adjust the suction power. After setting up, people can leave. When the interceptor is almost full, then clean it up.
