Abstract: A straining and transport system includes an extending flexible net system and an entrained drawing loop string for use in a catchment basin having a drain, An additional central basket portion may be integrated centrally into the net system proximate the drain and may be separately removable. The entrained drawing loop string is entrained with the net system about an outer perimeter portion so that during a tensioned use, the loop string gathers the perimeter portion together forming an encircling loop and securing any use debris in the flexible net system for removal from catchment basin. Other aspects of the invention include the use of rigid or semi-rigid portions replacing all or a portion of the net system and movable relative to a central portion for support. Additionally the net may include a retaining basket portion proximate the drain for additional catchment.
