Concepts of managing urban stormwater runoff with a microcontroller operated flow control system are presented. The microcontroller system allows flexible and precise flow control from stormwater detention reservoirs and is compared to a conventional flow control structure. Performance characteristics including peak runoff rate control, water quality improvement through increased detention time, minimization of detention reservoir overflow, onsite design refinement and flood routing are discussed. The microcontroller system has greater potential than conventional flow control structures in minimizing detention reservoir overflow and can be used to make onsite system adjustments based on observed performance and to optimize routing of flood water where downstream conveyance capacity is a constraint.
