Water storage and distribution
SUEZ ENVIRONNEMENT and its subsidiaries provide drinking water storage and distribution, thanks to the installation of high-performance distribution networks.
Treatment and storage: guaranteeing high-quality water, 24 hours a day
SUEZ ENVIRONNEMENT treats and purifies water to ensure that it is safe and good to drink when it reaches the consumer’s tap.
Inspections make it possible to continuously monitor the microbiological quality of water, a major challenge in the safety and preservation of water resource quality. The International Centre for Water and Environment Research (CIRSEE), has developed new analysis techniques based on molecular biology that can detect viruses, bacteria or parasites in water very quickly.
- SUEZ ENVIRONNEMENT supplies 91 million people with drinking water.
- Every day, 19% of the French population, or 12.3 million people, receive drinking water distributed by Lyonnaise des Eaux.
- 3.5 million people supplied with drinking water in Sydney (the Group meets 20% of Australia’s drinking water needs)
- 13 million inhabitants of China supplied with drinking water
- Present in 9 countries, Agbar serves over 26 million people
Water distribution: services with high added valuee
Drinking water is stored in water towers or underground tanks. It is distributed through a pipe system that requires ongoing monitoring and maintenance. Networks represent a major investment and an asset to be protected. With a comprehensive range of technologies and services, the Group covers almost all activities related to water network management.
The Group has vastly improved service performance through its many innovations:
- Development of remote meter reading
- Development of a method by CIRSEE for diagnosing the deterioration of pipes in contact with chlorinated disinfectants
- Installation of a leakage alert device that makes it possible to identify leaks in real time across the drinking water distribution network
- Installation of a new generation of acoustic sensors
- Use of eco-designed networks in the near future
- Implementation of PREVOIR® (optimised network renovation and recovery plan) to allow communities to plan for pipe renovation
In France, for example, Lyonnaise des Eaux signed a public service drinking water management contract with the city of Saint-Dizier (Haute Marne). It commits the company to a certain level of service performance in terms of protecting and preserving water resources. The priority task is to limit leakage on the 154 kilometres of the drinking water network. Lyonnaise des Eaux has committed to a 50% reduction in water losses on the existing network over four years. To achieve this goal, the company has:
- set up 180 permanent leak loggers and completed the installation of 20 sectoring meters on the drinking water network,
- planned to optimise network asset management by deploying hydraulic modelling tools and Geographic Information Systems (GIS),
- provided the city’s technical services with an intranet site for real-time monitoring of water system maintenance.
