Abstract
Stormwater from a watershed is collected in a stormwater collection basin for water quality improvement primarily by settling of suspended solids, and also for control of the flow rate through downstream flow channels. The outflow rate from the basin is governed by an adjustable water control device such as a gate valve operated by a motor under control of a microprocessor in accordance with predetermined conditions as sensed by sensors such as basin water level sensors, upstream flow or rainfall sensors, and flow rate sensors downstream of the basin. The effective capacity of the basin is increased by the ability to interactively adjust the flow rate from the basin based on sensor inputs indicative of anticipated inflow rates and the flow capacity of the downstream channels and water can be retained in periods of dry weather for irrigation and the like.
