Abstract
An apparatus for enhancing the water quality in a subterranean pressurized water system is disclosed and provides a discharge passage control via a valve that can be actuated electronically at the location of the valve or remotely. The discharge through the apparatus permits the flow of water in the subterranean pressurized water system and a corresponding discharge of contaminants and increased concentration of disinfectants supplied to the subterranean pressurized water system by the water system manager. The discharge can occur directly to a below ground drain such as a storm drain, sewer or drain field.
