The method of claim 1, further comprising: setting the residual set point level, the turbidity set point level, and the pH set point level by an operator of the flushing and sampling station. 3. The method of claim 1, wherein the flushing and sampling station further comprises: a flow controlled passage for pressurized water having an inlet adapted for fluid connection to the water distribution system, the flow controlled passage having a conduit for directing pressurized water received in the inlet to an above ground routing conduit for redirecting the pressurized water;the flow control valve disposed along the flow controlled passage for enabling the flushing of the water distribution system by permitting and prohibiting the flow of pressurized water through the flow controlled passage; anda water sampling apparatus for obtaining water sample data corresponding to a sample of the pressurized water from the flow controlled passage. 4. The method of claim 3, further comprising: determining a state change of the flow control valve of the flushing and sampling station; andlogging a time and date of the state change of the flow control valve. 5. The method of claim 4, further comprising: logging the residual level value of water in the water distribution system; logging the turbidity level value of water in the water distribution system; logging the pH level value of water in the water distribution system; andlogging a temperature level value of water in the water distribution system. 6. The method of claim 5, wherein at least one of logging the residual level value, logging the turbidity level value, logging the pH level value, and logging the temperature value occurs a predetermined time after determining a state change of the flow control valve. 7. The method of claim 1, further comprising: determining whether an alarm has been triggered;logging a time of the alarm when it is determined that the alarm has been triggered; andsending an alarm notification to an operator of the flushing and sampling station when it is determined that the alarm has been triggered. 8. The method of claim 1, further comprising: communicating with a remote location by responding to a data request from the remote location. 9. The method of claim 1, further comprising: displaying an operational status of the flushing and sampling station, the operational status including at least one of turbidity information, pH information, historical trend information, and data logging information. 10. A method of maintaining water quality in a water distribution system including: providing a flow controlled passage for pressurized water having an inlet adapted for fluid connection to a subterranean pressurized water distribution system, the flow controlled passage having a conduit for directing pressurized water received in the inlet to an above ground routing conduit for redirecting the pressurized water,providing a flow control valve disposed along the flow controlled passage for permitting and prohibiting the flow of pressurized water through the flow controlled passage;providing a memory;providing a water sampling device connected to a water source;placing a controller in signal communication with the flow control valve; andplacing a processor in signal communication with the water sampling device and the controller, and executing flushing programs stored in the memory, at least one of the flushing programs configured to cause the controller to open and close the flow control valve in response to a comparison between a current water property value from the water sampling device and a set point level for the water property according to a pre-determined hysteresis band related to a flush start signal and a flush stop signal correlated to the set point level; andinputting instructions to the processor via at least one interface in signal communication with the processor for execution by the processor. 11.
