ABSTRACT:
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.
