Abstract: A corrugated pipe manufacturing cell is configured to produce multiple corrugated pipes in parallel. The manufacturing cell may comprise an extrusion system that is capable of providing multiple independently regulated flows of plastic piping material to multiple die heads. The multiple die heads may feed a set of mold blocks having dual cavities for forming he multiple corrugated pipes. The pipe manufacturing cell may be converted between a first mode for producing large diameter single corrugated pipes, and a second mode for producing smaller diameter, plural corrugated pipes.

Abstract: A sleeve adapter for installation over a corrugated pipe is provided. The sleeve adapter may comprise a tubular body, wherein the tubular body may have a smooth outer surface, a first monofilament wire connected by a first one-way clamp, wherein the first monofilament wire may extend around a first end of the tubular body, a second monofilament wire connected by a second one-way clamp, wherein the second monofilament wire may extend around a second end of the tubular body, a flexible elastomer hinge extending around the tubular body, and a plurality of sealing surface fins extending outwardly from an inner surface of the tubular body.

Abstract: Embodiments of the present disclosure provide a stormwater drainage system including a multi-fit adapter for connecting at least one fluid pipe to a fluid basin. The multi-fit adapter may include a plate configured to be mounted on an outer surface of the fluid basin; and a plurality of concentric rings protruding from the plate. In disclosed embodiments, a curvature of the plate may correspond to a curvature of the outer surface of the fluid basin. In disclosed embodiments, each of the plurality of concentric rings may be configured to accommodate a fluid pipe.

Abstract: This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

Abstract: A media mixture for water treatment is provided. The media mixture may comprise activated alumina in an amount of from about 7% to about 17% by volume of the media mixture, activated carbon in an amount of from about 17% to about 42% by volume of the media mixture, and zeolite in an amount of from about 17% to about 57% by volume of the media mixture.

Abstract: Fasteners for fastening at least two parts, comprising one or more pins and one or more tabs on a first part, one or more holes and one or more connectors on a second part, and wherein the one or more pins of the first part are inserted into the one or more holes of the second part and the one or more tabs of the first part are snapped onto the one or more connectors of the second part to form a manifold.

Abstract: A coupling configured to connect a first pipe to a plurality of pipes comprising a first end and a second end, wherein the second end is tapered and comprises a plurality of lateral ribs and a plurality of longitudinal ribs, wherein each of the plurality of longitudinal ribs comprises a pliable and wedge-like shape, and each of the plurality of longitudinal ribs tapers toward the second end.

Abstract: A disclosed corrugated end cap includes a corrugated frame having one or more corrugations defined by one or more sets of alternating peaks and valleys. The end cap also includes one or more ribs disposed in one or more of the valleys and one or more valley reinforcements disposed in the valleys and running over a top surface of the corrugated frame. For example, the one or more ribs may be configured to increase a resistance of the frame to bending. Additionally or alternatively, the top surface, a front surface, and a rear of the corrugated frame surround a recess configured to receive latch ridges from a stormwater chamber.

Abstract: Stormwater management systems, methods, and apparatuses for containing and filtering runoff may be provided. In one implementation, a flared end ramp for managing flow of material into a stormwater chamber may be provided. The flared end ramp may include an inlet end configured for connection with a pipe, a side wall of the flared end ramp having a rounded profile at the inlet end; an outlet end configured for placement within the stormwater chamber; and an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the stormwater chamber. The outlet end of the flared end ramp may have a larger width than the inlet end of the flared end ramp such that the inclined surface is angled laterally outward from the inlet end toward the outlet end.

Abstract: A grease interceptor for use with a wastewater treatment system comprises a tank which is divided by a baffle into a first chamber and a second chamber. Wastewater flows from an inflow pipe into a first chamber of the tank. The wastewater may then flow through openings in the baffle to a second chamber of the tank. The wastewater may then flow through an outlet pipe in the second chamber to exit the system. The inflow pipe may comprise a flow restrictor which may restrict the flow of wastewater within the inflow pipe.
