Geographic Information Systems
Geographic Information Systems enable water utilities to manage systems and monitor flows. We use SAR satellite images in bands L or C to penetrate even heavy cloud cover and normal vegetation. We can identify water’s reflectance values in any weather, day or night, ensuring that water companies always have the data they need to find leaks and maintain their systems.
Our Analytical Approach
Overall Monitoring Process
Environmental conditions can affect the ability of any GIS water monitoring system to detect leaks. When requesting an analysis, it is important to understand the conditions in which the event has taken place.
|Event Condition||Is leak detectable?||Possibility of false alarm||Remark|
|Normal weather||Major leak: Yes
Minor leak: Yes
Monitoring water ponding can identify major leaks in normal weather. Monitoring changes in moisture of barren soil can identify minor leaks.
|Light rain (no ponding or inundation)||Major leaks: Yes
Minor leaks: No
Significant leaks leading to ponding can be identified. Minor leaks that only cause a change in soil moisture cannot be identified during light rain.
|Heavy rain (with ponding/inundation)||Major leaks: No
Minor leaks: No
Since heavy rain will cause widespread ponding, there will be no false alarms. However, water monitoring cannot detect leaks during periods of heavy rain.
|Snow||Minor leaks: No
Major leaks: Yes
Snow melts cause conditions similar to light rain. Water monitoring can identify major leaks but not minor leaks.
|Leaks from other sources
(e.g. leak from a water tanker near a pipeline)
|Major leaks: Yes
Minor leaks: Yes
Leaks from any sources will be identified. However, they will require additional information to minimize false positives.
Key Benefits of GIS Water Monitoring
24/7 Monitoring — Scanning and analysis is unaffected by cloud cover, traffic, noise, or time.
Clear Visualisation — Interactive dashboards visualize leakage hotspots and identify sites of concern.
Reduce Harm — Identify high priority leaks quickly, reducing potential damage and claims.
Efficient Engineering — Field engineers only need to survey confirmed locations, enabling an efficient use of human and financial resources.
Faster Repairs — When you know the leak’s location, confirming and fixing it is fast and easy.
Constant Surveying — Check your entire system multiple times a month instead of only once every few years.
