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.

1. In a golf course recirculating irrigation system including a reservoir, the improvement comprising an apparatus for removing underwater debris from said reservoir of said golf course recirculating irrigation system by entraining said debris in water and pumping said entrained debris out of said reservoir, comprising:eductor means for vacuuming said debris out of said reservoir, said eductor means including a high pressure water inlet, a vacuum line inlet and an outlet, said vacuum line having a first end connected to said eductor means, said vacuum line having a second end movable in said reservoir, pump means for driving said eductor means, said pump means having an inlet line connected to a source of water, and said pump means having an outlet line connected to said eductor means to deliver high pressure water to said eductor means, whereby said second end of said vacuum line is adapted to remove said debris from said reservoir entrained in water from said reservoir, and is adapted to carry said entrained debris to said eductor means, and separation means for separating said entrained debris from the water in which said debris is entrained as said entrained debris is discharged from the outlet of said eductor means. 2. The apparatus of claim 1 wherein said separation means comprises a temporary, permeable dam through which water passes freely but which traps and separates said debris from the water in which it was entrained.3. The apparatus of claim 2 wherein said permeable dam is enclosed.4. The apparatus of claim 1 wherein said separation means comprises two concentric, permeable dams.5. The apparatus of claim 2 wherein said permeable dam comprisesa plurality of steel stakes driven into the ground, a layer of open mesh plastic attached to said stakes, and a layer of fine mesh fabric adjacent said layer of open mesh plastic. 6. The apparatus of claim 1 wherein said separation means comprises a prefabricated, plastic cylinder, said cylinder having a plurality of drain holes formed therein, and a fine mesh filter covering said plurality of drain holes.7. The apparatus of claim 1 wherein said separation means comprises:a trailer, a permeable dam carried by said trailer for separating said debris from the water in which it is entrained. 8. The apparatus of claim 7 wherein said permeable dam extends across the back of said trailer.9. The apparatus of claim 7 wherein said permeable dam is carried on the bed of said trailer.10. The apparatus of claim 1 wherein said separation means comprises:a dump truck, a permeable dam carried by the bed of said dump truck. 11. The apparatus of claim 10 wherein said permeable dam extends across the back of the bed of said dump truck.12. The apparatus of claim 10 wherein said permeable dam is carried on the bed of said dump truck.13. The apparatus of claim 1 wherein said separation means comprises:a conveyor, a plurality of permeable members carried by said conveyor. 14. The apparatus of claim 13 wherein said conveyor is domed along its longitudinal center.15. The apparatus of claim 1 further comprising:a clean out carried by said eductor means adapted to allow a user to readily clear a clog in said eductor means. 16. The apparatus of claim 1 wherein said eductor means further comprises a conical mixing chamber, a cover for said mixing chamber, a nozzle slidably carried by said cover, and means for adjusting the position of said nozzle in said mixing chamber.17. The apparatus of claim 1 wherein said eductor means has an outlet and a priming flap carried by said outlet.18. The apparatus of claim 1 further comprising:injector means connected to said vacuum line to inject water into said vacuum line to increase the flow rate of water and entrained debris in said vacuum line. 19. The apparatus of claim 1 further comprising a collection chamber positioned in said vacuum line to separate out relatively large pieces of debris that may otherwise clog said eductor means.20. The apparatus of claim 19 wherein said collection chamber comprises:an elongated, vertically extending body, a removable cap carried by the top of said body, a removable separation cage carried inside said body, said cage adapted to trap large pieces of debris that may otherwise clog said eductor means. 21. The apparatus of claim 1 wherein said eductor means includes a plurality of eductors, each having its own separate vacuum line.
