Patent ID: 8585321

Claim:
A flow control system for integration into a detention pond, the flow control system comprising: a stationary riser, the stationary riser having a stationary riser hollow core, an axis of the stationary riser hollow core being vertical, the stationary riser hollow core fluidly connected to a drainage system; a movable riser, the movable riser slideably interfaced with the stationary riser, the movable riser having a hollow core, an axis of the hollow core being vertical, a top surface of the movable riser having an opening, the hollow core fluidly connected to the stationary riser hollow core whereas liquid from the detention pond flows through the opening, through the hollow core through the stationary riser hollow core and out of the stationary riser hollow core and into the drainage system; at least one vent tube, a first end of the vent tubes positioned above the liquid of the detention ponds and a second end of the vent tubes venting the movable riser hollow core, thereby equalizing air pressure between an atmosphere above the detention pond and an air pressure within the movable riser hollow core; and at least one float interfaced to the movable riser, the at least one float providing buoyancy to the movable riser.
