Abstract: A cellular container assembly comprises collapsible linked two-layer, open-ended structure containers formed of opposed container walls. The containers are formed by weldment at opposed contacting wall portions to form multiple cells for retention of a soil mix and an associated plant. The assembly also comprises a soil drain board upon which the containers are supported. The drain board defines a fluid permeable mat having pylons and a foraminous screen resting upon the mat. The drain board is mounted in a watertight box to confine the containers and drainage board. A drain in the box recycles fluid or permits runoff.

The assembly also comprises a soil drain board upon which the containers are supported. The drain board defines a fluid permeable mat having pylons and a foraminous screen resting upon the mat. An impermeable liner rests within a box with the liner being interposed between the box and drainage board to confine the containers and drainage board. A drain in the liner recycles fluid or permits runoff.

Abstract: A hydrant flushing diffuser handles a flow of water from a hydrant as it is being flushed. The diffuser allows the flushing to take place in a safe manner and without destroying surrounding landscaping or other objects. The invention includes a hydrant flushing diffuser having a hood and a chute. The hood has a closed top and an open base and includes an aperture. The chute further comprises a porous fabric bag that is open on one end, wherein the chute is connected to the hood so that open end of the bag surrounds the aperture in the hood.
