Abstract

The present disclosure relates to maintaining water quality in a water distribution by controlling a flushing apparatus. In one example implementation, a flushing apparatus performs steps comprising flushing the water distribution system in accordance with a residual flush program, flushing the water distribution system in accordance with a turbidity flush program, flushing the water distribution system in accordance with a pH flush program, and flushing the water distribution system in accordance with a time-based flushing program.

First claim

What is claimed is:

1. A method of maintaining water quality in a water distribution system using a flushing and sampling station, comprising:
flushing the water distribution system in accordance with a residual flush program stored in a memory of the flushing and sampling station, the residual flush program configured to activate a flushing mechanism comprising a flow control valve in fluid connection to the water distribution system, activation of the flushing mechanism comprising opening and closing the flow control valve in response to a comparison between a sampled residual level value and a residual set point level according to a pre-determined hysteresis band related to a flush start signal and a flush stop signal correlated to the residual set point level;
flushing the water distribution system in accordance with a turbidity flush program stored in the memory of the flushing and sampling station, the turbidity flush program configured to activate the flushing mechanism by opening and closing the flow control valve in response to a comparison between a sampled turbidity level value and a turbidity set point level according to a pre-determined hysteresis band related to a flush start signal and a flush stop signal correlated to the turbidity set point level;
flushing the water distribution system in accordance with a pH flush program stored in the memory of the flushing and sampling station, the pH flush program configured to activate the flushing mechanism by opening and closing the flow control valve in response to a comparison between a sampled pH level value and a pH set point level according to a pre-determined hysteresis band related to a flush start signal and a flush stop signal correlated to the pH set point level; and
flushing the water distribution system in accordance with a time-based flushing program stored in the memory of the flushing and sampling station, the time-based flushing program configured to activate the flushing mechanism by opening and closing the control valve based on at least one program parameter when it is determined that the time-based flushing program is active.

2. 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; and
a 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; and
logging 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; and
logging 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; and
sending 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; and
placing 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; and
inputting instructions to the processor via at least one interface in signal communication with the processor for execution by the processor.

11. The method of claim 10 , further comprising:
receiving water sampling data from the water sampling device;
storing the water sampling data in the memory; and
transmitting the water sampling data to at least one remote device.

12. The method of claim 11 , wherein the water sampling data includes the current water property value.

13. The method of claim 10 , wherein the water property comprises one of disinfectant residual, pH, turbidity, and temperature.

14. The method of claim 10 , wherein the interface is a web page.

15. The method of claim 10 , wherein the interface is a SCADA system.

16. A method of maintaining water quality in a water distribution system using a flushing and sampling station, comprising:
flushing the water distribution system in accordance with a plurality of flushing programs stored in a memory of the flushing and sampling station, at least one of the plurality of flushing programs configured to activate a flushing mechanism of the flushing and sampling station, the flushing mechanism comprising a flow control valve in fluid connection to the water distribution system, activation of the flushing mechanism comprising opening and closing the flow control valve in response to a comparison between a sampled water property value determined by the flushing and sampling station 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;
