INTRODUCTION 

Water pipes serve as crucial life lines for maintaining daily lives. • Constantly function - ensure high reliability. • Malfunction/damage - minimum/rapid recovery.



Discharge monitoring will go a long way in; detection of pipe bursts and quantifying discharge for engineering areas such as water storage design, water rationing, ensuring that customers are receiving water regularly and efficiently.  The Water Act 2002 seeks to; • initiate reforms in the water sector and, • to develop a national monitoring of and information on water

resources.

PROBLEM STATEMENT 

Water pipes breakage results in: • quantitatively large volume of water loss from the time of

breakage up to the time of delayed repairs. • causing major financial losses. 

The delays for repairs happens due to lack of a timely alert system to prompt the water providers of the problem at the time and locations (approx) of occurrence.



Non-revenue water that results after installation of illegal connection - huge amount of revenues losses. Thus, the need for a systems to support a rapid recovery.

General:

OBJECTIVES

• To develop a real-time web-based water discharge

monitoring map application 

Specific:

• To develop a module to send the data availed to the gprs

module by the sensor to a database. • To develop modules for parsing data values to and from the database. • To develop a module for water discharge visualization at point locations on a map. • To develop a module to display multiple water discharge charts for comparison between two sensor locations.

APPLICATION FEATURES 

The interface customizations included: • Onclick features - for network display, sensor location display and areal boundary display. • Google maps sensor locations icons • Infobox with interactive real time charts visualization at sensor locations. • Pop up interactions of all the map elements for displaying their properties to the user • Pop up box with multiple Y-axis values for water discharge comparisons between two sensor locations. • Tooltip chart capabilities – chart queries

FINAL MAP APPLICATION

CONCLUSION 

The ideation and development of the real-time web-based water discharge map application was a success with the use of web mapping tools and javascript capabilities.



Web mapping tools - a convenient for real time map applications  effective spatial decision support tool for water network failures mitigation and thus improving the efficiency of recovery operations.



The application provides the basic water monitoring platform that can be used for rapid recovery measures.
