Abstract: The present up-flow water filtration system is made up of three or more layers. In the example of three layers, each layer is individually rigid and capable of supporting loads above it, and each serves a separate function. These layers include the inlet layer on the bottom of the system, the outlet layer at the top of the system, and the central layer in between which contains the filter media. Additionally, the system includes one or more vertical ports that are open above ground and that extend into the central layer and provide access to the central media containment layer for maintenance. There are also several layers of textiles which form the flexible outer casing, as well as internal membranes to separate the different layers and components of the system. Some systems may include inlet and outlet pipes, but other inlet and outlet configurations are possible.

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.

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.

Abstract: The assemblage consists of an in-ground assembly container 100 for plant propagation, formed of plastic strips 112 joined together to form, when compressed, a honeycomb configuration of container cells 110. Each cell is used to grow individual types of trees or plants. Walls of the cells are respectively embossed to enhance containment of potting soil. By combining the honeycomb container cells 110 with a pervious mat 120 and an impervious supporting liner 130, applied nutrients and water will not escape into the ground soil except by controlled pipe drainage 140. This combination will thus allow for total water and nutrient recirculation back through the system. The outlay includes a PVC liner 130, an optional drainage layer 120 and weed control fabric 122.
