Abstract: A drainage treatment system for minimizing debris entering a drainage system is described herein, the system including a support housing supportingly received in the drainage system downstream of an opening thereof. The support housing includes a first drainage means for allowing liquid to flow therethrough. The system also includes a first insert for collecting debris, the first insert having a second drainage means for allowing liquid to flow therethrough while preventing the flow through of debris. The first insert is removably supported within the housing such that when in place, the first and second drainage means align, permitting liquid to pass through the drainage treatment system. In use, debris collects in the system and is removed therefrom by removing the first insert from the support housing.

Abstract: A plug assembly (11) adapted to be received in an opening at a first end of a pipe (13) for preventing debris passing therein. The plug assembly (11) comprises a first portion (21) adapted to be received in the opening, and a second portion (23) to ensure the first portion (21) does not move inwardly away from the opening. The plug assembly (11) also comprises a drainage means (33) to allow fluid to pass through the plug assembly (11).
