ABSTRACT:
An apparatus and method are provided for removing accumulated underwater debris from a reservoir for a recirculating water system, such as used for a golf course sprinkler system. An eductor is provided which is driven by a high pressure water pump. The high pressure creates a vacuum which is utilized to actuate a vacuum line. The vacuum line is moved to and fro in the reservoir to entrain the debris from the reservoir in water and to carry the entrained debris to the eductor. The entrained debris is discharged from the eductor into a separator having a permeable membrane which traps the debris and allows the water to return to the reservoir. Various separators are provided. The eductor includes an adjustably mounted nozzle to adapt to different sized debris being removed from the reservoir.
