How it works

Satellite images taken from optical or thermal cameras/sensors can work only in day light and do not work in case of cloud cover. We use SAR satellite images in L band or C band to perform our analysis using reflectance values including special spectral signature for water. SAR images can penetrate the clouds and normal vegetation to reach to the surface of the earth. Hence, we can conduct survey in all weather, day and night including when there is a heavy cloud cover.

Approach


1. Acquire

Acquire related Satellite data of geographical area to be analyzed. These data is used in combination with other geographical, weather, water pipeline information. .



2. Organize

All data is passed through data adapters for transformation and integration into required format. These data with other historical data is used for deep learning training. .



3. Process

Hydraulic AI Algorithm is used to process the cooked data to identify special spectral signature for water leak. Radiometric corrections are applied to achieve final result. .



4. Improve

Identified locations of the incident are further verified with weather information, other geographical data to avoid raising false alarm and filter incidents only with high confidence. .



5. Apply

Result can be reported through our web/mobile. We can also integrate with APIs provided by us to your existing applications or provide you raw files for further use. .


Overall Monitoring Process


1. Locate

First stage is to find the location of incident (water leak, flood, etc.). Satellite data is used in combination with other geographical, weather, water pipeline information. These data is passed through AI algorithms to detect the locations of events. .



2. Report

Once location of the water incident is known it can be reported to concern users through web portal/mobile app provided by us. We can even integrate with APIs provided by us to your existing applications or provide you raw files for further use. .



3. Assign

A field engineer or any individual responsible for taking further action can be assigned to take up the further activity on the identified incident. He/she decide the next course of action required on this. It would help to start overall fix process. .



4. Verify

Next step is to verify the incident either by physically visiting the location or any other means at your disposal. Standard practice is for field engineer to visit the location and verify the problem and scale of the incident so that further action can be taken. .



5. Control/Fix

Once verified we then need to control the problem and provide permeant fix for the problem. After fixing the status can be updated into the system and relevant parties are notified of the status. If required, RCA can be performed for preventive measures. .



6. Analyze

Realtime dashboard is provided to the stake holders to keep track of the overall status about all incidents. Also, historical trend analysis reports help to identify reoccurring problems which can act as Ker performance indicator for further action. .


Complex Scenarios

Scenario Is leak detectable?​ Chances of false alarm?​ Remark​​
Normal weather​ Major leak: Yes​
Minor leak: Yes​
No

Major leaks can be identified by monitoring the ponding. Minor leaks can be identified by monitoring the change in soil moisture (in the case of barren soil).​

Light rain (no ponding/inundation)​ Major leaks: Yes​
Minor leaks: No​
No

Significant leaks causing ponding conditions can be identified. Minor leaks ( leading to the change in soil moisture only) can not be identified.​

Heavy rain (with ponding/inundation)​​ Major leaks: No​
Minor leaks: No​​
No

Since heavy rain will cause ponding in several parts compared to leaks which are usually isolated events, there will be no false alarms. However, leaks during this period can not be detected.

Snow Minor leaks: No​
Major leaks: Yes​​​
No

During the melting phase of snow, it is similar to the light rain case and minor leaks can not be identified.

Leak from other sources​
(e.g. leak from water tanker over pipeline)​
Major leaks: Yes​
Minor leaks: Yes​
Yes

Leaks from any sources will be identified as the leaks, will require additional information to minimize the false alarms.​

Key Benefits

Unaffected by weather, traffic, noise, time.​

Interactive dashboards to visualize the leakage hotspots and drive directly to location in concern

Priority Leaks can be targeted quickly reducing potential damage and claims.

More efficient use of human and financial capital resources as field engineer has to survey key selected locations only​

Due to the high confidence in the location precision, the confirmation process of whether a finding is a leak or not takes very less time​

The entire system can be surveyed up to multiple times rather than once every 1-5 years or less. ​
