The present invention relates to a device comprising a coherent manmade vitreous fibre substrate (MMVF substrate) and at least one first conduit (2) and at least one second conduit (3), each conduit having first and second open ends, wherein the MMVF substrate (1) comprises man-made vitreous fibres bonded with a cured binder composition, wherein the first open end of the first conduit and the first open end of the second conduit are each independently in fluid communication with the MMVF substrate, wherein the first conduit is at a greater height than the second conduit, wherein at least a portion of the MMVF substrate is disposed between the first and second conduits. The MMVF substrate provides for an increased water storage ability due to the hydrophilic behaviour of the substrate and its increased surface.

A modular system for reducing the total suspended solids of waste, including scum, sludge and water layers, includes a plurality of chambers each being connected in succession by a corresponding one of a plurality of flow pipe segments including an inlet segment, an outlet segment and at least one middle segment, wherein the waste enters the septic tank via the inlet segment and is transferred between each of the plurality of chambers via the at least one middle segment; a corrugated flow pipe in fluid flow communication with the outlet segment; and the corrugated flow pipe being sized and configured for use as a settling zone for removal of a portion of the total suspended solids and wherein an amount of water from the water layer within the chamber adjacent the outlet segment enters the corrugated flow pipe and passes through the outlet segment.

An expansion ring mountable in a storm drain for supporting a filtering apparatus includes a ring-shaped expansion member having an adjustable diameter which is cut transversely to define two open end portions thereon which face each other and which are separated from each other by a predetermined distance to define a gap therebetween. A wedge assembly is positioned at the gap between the open end portions of the expansion member and is adjustable to increase the diameter of the expansion member. When the wedge assembly is adjusted to increase the diameter of the expansion member, the expansion member tightly engages a side wall of a portion of the storm drain in which the expansion ring is mounted to secure the expansion ring, and a filtering apparatus supported thereby, in a desired position.

A sump system includes a catch basin and a sump pump. The catch basin is configured to receive runoff water. The catch basin has an upper end and a bottom surface. The catch basin defines a vertical chamber and a horizontal chamber. The vertical chamber extends downward in a vertical direction from the upper end to a first portion of the bottom surface. The horizontal chamber intersects the first chamber to form an intersecting region. The horizontal chamber is defined by an upper surface and a second portion the bottom surface. The horizontal chamber extends outwardly in a horizontal direction from an outer periphery of the first chamber and has a vertical dimension that extends upward from the bottom surface to the upper surface. The upper surface is positioned below the upper end. The sump pump is disposed within the catch basin.

An automated water control device comprises a rotatable housing that can be incrementally positioned to control flow of water over an upper or weir edge of the housing. The device is installed at a control point in an impoundment area, such as a settling pond. The housing is selectively rotated to raise and lower the height of the weir edge to a target gate height. Automatic control is provided for operation of the device by a controller communicating with an actuator. A system of the invention includes one or more water control devices and the controller. A method of the invention includes controlling flow of water from an impounded water source by use of the automated water control device. Manual or semi-automated embodiments are also disclosed.

A frameless, modular connector pipe screen insert designed for installation within storm water infrastructure, including a catch basin, for the treatment of storm water by removing trash and debris from incoming water flow. The connector pipe screen is optimally designed with perforation sizes and void areas to remove trash and debris; thereby preventing further pollution of nearby water systems including rivers, lakes, and oceans.

A stormwater drain baffle to be disposed in a flow-through stormwater sump or chamber for baffling a stormwater flow-path. The baffle has a plurality of openings distributed over the area of the baffle. The baffle comprises at least two baffle portions connected to each other. The baffle portions are disposed near to and in superposed relation to each other, so that the baffle portions overlap each other and are adjustably connected to each other for adjusting the width (W.sub.tot) of the baffle. At least the outermost baffle portions of the baffle comprise fixing members which are monolithic with the baffle portion and adapted for fixing the baffle to the vertical inner wall of the sump or the chamber.

Surface water, such as stormwater, is contained in a pond, or other containment having primary semi-isolated treatment areas constructed, or designated therein, which are suitable for establishing ecological communities for treatment of water within the containment. Water for treatment is induced to flow through the semi-isolated areas and the ecological communities therein for treating the water, such as by bio-filtering, breakdown and bioremediation of water-soluble or hydrocarbon-based contaminants and inhibition of the proliferation of waterborne pathogens. The treated water is then discharged from the semi-isolated areas, such as for use downstream. Discharge of the treated water from the primary semi-isolated treatment areas, as well as the use of pump systems, induces the flow of water through the semi-isolated areas and ecological communities therein to effect the treatment. Ecological communities may be established in relatively shallow secondary treatment areas in the containment and the recirculation of water therethrough may further act to treat the water in the containment.

The invention described is a pipe guard that prevents unwanted debris from entering a pipe while still allowing the flow of water. The pipe guard includes braces connecting a mounting flange on the outside of the pipe to a plate within the pipe having a plurality of holes. A bracket extends from one brace to the other between the flange and plate to provide additional support and rigidity to the pipe guard as well as acting as a handle that can be grasped by a worker to remove the pipe guard and material that may build up on the plate. The pipe guard is secured within the pipe by fasteners that extend through threaded holes in the braces and partially embed into the interior wall of the pipe. Accordingly, the pipe guard cannot be pulled free from or knocked loose from the pipe without loosening the screws.
