A system for monitoring and controlling a flow of fluid in an environment and a method of using the system to control the flow of fluid in the environment. The system comprises a main valve positioned at an entry point of the environment. The main valve permits fluid to be discharged into the environment upon receipt of an authorized request to a controller from one or more authorizing signaling devices. The controller communicates with the authorizing devices and processes signals from the authorizing signaling device to control the flow of fluid in the environment. The system may also comprise one or more monitoring signaling devices positioned in the environment intermediate the main valve and an authorizing signaling device.
