Synthesis of the problem
 Constant increase of water demand
 Exponential decrease of natural resources
Is the water distribution system able to address
these changes?
Up to 70% of water is lost along the distribution
path
Expedite and refine leakage identification
procedures

Leakages in
Water Distribution Networks
How to know about presence of breaks?
If known, how to find breaks along the path?
The path is known?
If not, how to locate pipes?

Conclusions and Recommendations
Conclusions and Recommendations
Mobile Sensor
Networks are
fundamental even
underground
Some complex
solutions are
already written in
the past
Luxor, Egypt, 14-15 April 2013
Enhance
standardization in
WSN
