Abstract
An application for a flow control system includes a vertically oriented expanding conduit, positioned within the interior of a container which is fluidly interfaced to a downstream drainage system. The lower end of the expanding conduit is in fluid communication with an upstream reservoir through a closed conduit. A means to restrain the expanding conduit from lateral movement is provided and the means is in fluid communication with the interior of the container. The distal, upper end of the expanding conduit is capped and at least one fluid passageway opens through the cap from the interior of the expanding conduit. As the fluid pressure rises in the expanding conduit in response to an increase in the fluid level in the upstream reservoir, the fluid passageway through the capped, upper end of the expanding conduit rises to prescribed level and the release rate of fluid into the downstream drainage system is maintained at a prescribed rate or range of rates as the fluid level continues to rise.
