Abstract

An Anti-Terrorism water quality monitoring system for continuously monitoring a potable water treatment system and related potable water distribution network that provides potable water to a municipality, city, housing development or other potable water consumer. The system includes the collection of data from the water distribution system and from the water treatment facility and from advanced separation processes which are integrated into analytical instruments. The data collected are stored in a remote database on a remote server computer or bank of computers and accessible by Homeland Security or its designated agency. Preferred parameters of monitoring include the turbidity and disinfectant such as chlorine, hypochlorous acid, sodium hypochlorite, calcium hypochlorite, ozone, chlorine dioxide, chloramines, hydrogen peroxide, peracetic acid.

First claim

I claim:

1. A system for real-time web-based monitoring of water utilities, the system comprising:
a web-based data management device configured to:
obtain periodically from one or more remote sources data based on water quality sensor readings;
compile the data into a database;
update the compiled data based on new data from the one or more remote sources;
analyze the compiled data to determine whether a predetermined alarm condition exists and whether the alarm condition satisfies a predefined requirement to obtain an analysis result;
format the analysis result for a color coded graphical display, such that an individual having been authorized to access the web-based management device can assess a current state of the system performance based on the display;
generate a customized report based on the analyzed data;
send the analysis result to a user interface device for display;
continuously update the analysis result based on the updated compiled data; and
provide information relating to the analysis result to authorized individuals.

2. The system of claim 1 , wherein the graphical display indicates normal system operation, warning status, and alarm conditions.

3. The system of claim 1 , further comprising sending the customized report to pre-selected recipients if the alarm condition satisfies the predefined requirement.

4. The system of claim 1 , wherein the customized report includes a regulatory compliance report.

5. The system of claim 1 , wherein the customized report includes an exception report indicating instances where conditions were close to triggering an alarm.

6. The system of claim 1 , wherein the information includes an alarm signal.

7. The system of claim 1 , wherein the customized report includes a work order with predefined inspection checklist.

8. The system of claim 1 , wherein the customized report includes a summary of work order and maintenance schedule.

9. The system of claim 1 , wherein the customized report includes a regulatory compliance report.

10. The system of claim 1 , wherein the customized report includes a trend modeling report when conditions appear likely to exceed normal alarm conditions.

11. The system of claim 1 , wherein the customized report includes a financial oversight report.

12. The system of claim 1 , wherein the data management device is further configured to display the historical data in a geographical form.

13. The system of claim 1 , wherein the providing of the information includes automatically sending the information to the authorized individuals using multimedia messaging including e-mail, pager, or facsimile.

14. The system of claim 1 , wherein the data management device is further configured to display historical data concerning the water management system.

15. The system of claim 1 , wherein the data management device is further configured to display historical data in a geographical form.
