Abstract: A specially designed hatch apparatus and method for entry to a water treatment chamber containing media for water treatment. The hatch's shape, specially embodied hatch/media gap seal and position allows normal chamber operation and access to the lower chamber cavity for cleaning and maintenance time through treatment media.

Abstract: A water purifying apparatus and system capable of sedimenting particulates in the fluid over time, and allowing for the quick flushing of sedimented particulates. Top and bottom baffles act as barriers for the sediments, with the bottom barriers having a removable barrier.

Abstract: A floating strainer is constructed having a rectangular frame. A cylindrical drum is attached to each corner of the rectangular frame. Below the rectangular frame, a box-strainer is fixed. The distance between the box-strainer and the rectangular frame is adjustable so that the level at which water is drawn can be raised or lowered. The bottom of the box-strainer includes hose connections. These are positioned so that the hoses connect at the bottom of the floating strainer and extend vertically down from the bottom. This configuration operates to distribute the weight of the hose and reduce stress and strain on the hose.
