Systems and arrangements for mitigating environmental damage caused by storm water carried pollution

摘要

A pollution mitigation system is disclosed. The system can include a valve forming a passage the valve installable to form an orifice in a storm drain retention chamber that passes storm water into a conduit of a storm water management system. The valve having a stem connected to a closure member that can plug the orifice. The valve can have a spring loaded actuator that can move the closure member into a closed position. The system can also include a node such as a wireless sensor node or a mote that has sensors, a transceiver, an antenna, a microcontroller, memory, an energy source and at least one output to control movement of the closure member via the preloaded actuator. The node can have an output that provides the stimulus to the preloaded actuator to cause the preloaded actuator to move the closure member to a position that obstructs the passage in response to either the sensor or a transmission from a mobile telephone such as a cell phone or a smartphone.
