A plastic arch-shape cross section corrugated stormwater chamber has a multiplicity of crest corrugations and valley corrugations which run transverse to its length. Sub-corrugations run along part or all of the arch-curve lengths of either crest corrugations or valley corrugations, or along both of them. A sub-corrugations are smaller in dimension than an associated crest corrugation or valley corrugation. Sub-corrugations may taper in width and depth and may taper to nothingness. A compound convex shape end cap, useful for closing off the ends of stormwater chambers, has substantially vertical corrugations with analogous sub-corrugations.

A temporary sediment retention assembly for removing sediment from storm water entering an inlet of a storm water drainage system can include a substantially rigid frame and a cover. The cover can include a cover material that includes one or more sections of filter materials. The sections of filter materials can be substantially integrally formed or can be connectable together, and form or define a covering or cap that is adaptable to fit over and substantially cover the frame of the temporary sediment retention assembly for retaining or filtering sediment and debris from water flowing through the temporary sediment retention assembly and into the storm water drainage system.

Methods, apparatus, and systems involving wastewater treatment systems are provided. Plastic grids, with first and second legs are provided. These first and second legs have distal ends separated from each other. Flat pipes are also provided for wastewater treatment systems.

Disclosed in the present application is a system for a storm water and traffic collector box culvert. The system may comprise a plurality of reinforced slabs with an upper slab that may be configured as a reinforced surface to collect storm water runoff. The plurality of slabs may be connected by a plurality of attachment mechanisms. Accordingly, the present system is directed to an environmentally friendly culvert design that can minimize the magnitude of earthworks required by traditional drainage systems while also providing increased drainage capabilities. The Environmentally friendly design will contribute to the efficiency and effectiveness of the American Urban Infrastructure in reducing the drainage and traffic congestions.

An inlet filter and method of use are disclosed. In one aspect, the inlet filter comprises a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame is configured so an exterior of the frame is shaped like a wedge. In another aspect, the method comprises inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. In a third aspect, a system comprises a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

A distributed utility system includes water source supply lines capable of being placed in fluid communication with a separate water source, water discharge lines capable of being placed in fluid communication with a separate water discharge destination, a water source and destination control manifold to allow selected water source supply lines to be placed in fluid communication with selected water discharge lines, and a storm water collection and distribution system. The storm water system includes a storm water collection conduit and a collected storm water discharge line in fluid communication with the storm water collection conduit, and the storm water discharge line can be placed in fluid communication with the plurality of water discharge lines via the control manifold. The distributed utility system further includes a utility line disposed within at least one of the water source supply lines, water discharge lines and collected storm water discharge line.
