Abstract
An application for a flow control system includes a tapered plunger situated within an conduit. The conduit is open to a downstream drainage system. The tapered plunger is buoyant, assisted by one or more floats attached such that, when the water level around the flow control system increases to a pre-determined level above a top rim of the conduit, the tapered plunger lifts due to the buoyancy. In such, the flow rate is maintained substantially constant. At the emergency level, alternate drain systems provide increased drainage to reduce the potential of flooding.
