6. CHLORSCAN SENSORS IN THE DISTRIBUTION SYSTEM
• Since 2004, 104 Chlorscans sensors have been
operated online and in real time throughout Paris.
7. Real time pipe burst detection
Pipe Break detection by observing brutal real-time pressure fall and rising flow
- Low alarm pressure threshold on the scada system: all the real time pressure are
defined in the scada system with such a threshold alarm.
- High and low alarm flow threshold on the scada system.
This method can detect brutal change in water distributed volume, it is less sensitive to little
leakage.
8. District Metering Area Definition
30 sub areas have been defined for the city.
180 flow-meters used (real time and differed time).
All the water transfers between areas is count and manual valves are closed
if necessary.
9. Leakage Detection
Leakage detection with increasing average night flow and daily distributed volume
Most of leakage detection are detected with the average night flow and confirmed with the
daily distributed volume.
Rising detection has to be correlated with operation events (it can be due to filling swimming
pool for example).
Average night flow Daily distributed volume
10. AMR systems in Paris
The meter reading systems developed and installed in Paris since 2004 by Suez
and Veolia differ from one another. On the Right Bank of the Seine (2/3 of Paris),
Veolia has chosen a bi-directional short-range system; whereas Suez on the Left
Bank (1/3 of Paris) preferred uni-directional long-range system.

The information of the 93 000 meters are transmitted once a day.
The information of these meters are aggregated per area and allow the short differed time
comparison with the input water in order to identify leakage growth.
Data are available after three days.

12. SMART GRIDS FOR THE WATER
SYSTEM IN PARIS ?
What is the limitation of the current state
practice and the business case for Smart
Grids ?
è
Optimization of Operational Management (operator’s
performance)
è
Redefinition of Asset Management – best choice with
uncertainties assessment (operator’s performance)
è
Efficient Master Planning – best investment in larger
context prevision (system performance)
13. SMART GRIDS FOR THE WATER
SYSTEM IN PARIS ?
What are the challenges and priority needs
for which Smart Grids is useful ?
è
Water losses reduction in the distribution pipe network
by active leakage detection and repair;
è
Pipe burst prevention and reduction of their social costs
by efficient renewal of the conduits;
è
Reduction of water quality defaults identified by
sampling analysis and customer’s complaints;

17. Conclusion
Technology trends and new concepts for water integration in the global
urban management are deemed to provide future improvements through
better asset management, new services to the customers and better
response to consumer’s expectations.
Smart Grids have shown results in the Energy business; application in the
Water business is still awaited.
The water infrastructure deployed in Paris already offers many advantages
in the daily operation of the system, but more can be done. According to the
experience of Eau de Paris, three particulars points of the leakage detection
process can considerably be improved:
•
Amelioration of the whole system of AMR transmission in order to make the
existing system become ‘Real-time’ system.
•
Development of anomalies detection process using new algorithms.
•
Develop and establish appropriate response based on identified anomalies.
Lille university’s water network will be a very relevant place to make possible
a project for developing such a whole process.
