Disclosed is a fluid, namely stormwater, management system employing a chamber having an overall substantially constant curve cross-sectional geometry, with an a-semicircular constant curve cross-sectional geometry preferred. This chamber, which preferably follows both AASHTO standard specifications for Highway Bridges, Section 18, and Corrugated Polyethylene Pipe Association (CCPA) specifications, can further comprise corregations, support members and/or connecting elements to further add structural integrity.

Stormwater management system

An arch shape cross section chamber for receiving and dispersing stormwater when buried beneath the surface of the earth is corrugated and has a cross section geometry which is a continuous curve. Preferably, the curve is a truncated semi-ellipse. A chamber also has a combination of a standard corrugations along most of the length, in combination with smaller end corrugation with standard corrugations, to enable joining of chambers in overlap fashion, as a string; corrugations which have elliptically curved corrugation widths when viewed from the side of the chamber; and, sidewall base flanges which have turned up outer edges in combination with fins which connect said edges with the curved chamber sidewall. A domed end cap is adapted to both close the end of the chamber and to be positioned within the chamber length to provide a baffle.

Corrugated stormwater chamber

Apparatus for receiving and dispersing stormwater beneath the earth surface is comprised of an array of chambers, preferably having arch shape cross section, buried in crushed stone. Surface stormwater flows first through a diverter, then into a solids retention subsystem (SRS), and then into the array of chambers, which is spaced apart in the stone from the SRS. The SRS chambers are layered with geotextile or other filtering media. Solids entrained in the stormwater are retained in the SRS by a combination of settling and filtering actions. If the stormwater inflow exceeds the capacity of the SRS, the water level rises in the diverter to the point where it flows through a bypass line, directly to the chambers of the array.
