Suez Environnement wins contract to improve water quality in Paris, France

Suez Environnement has won a 12 year Public Service Delegation contract worth €639m from Gennevilliers Water Syndicate (SEPG) to improve the water network and services in ten localities of Paris commune in France.

The French utility has won the contract through its subsidiary Lyonnaise des Eaux.

Under the contract, Lyonnaise des Eaux will reduce water leakages across the SEPG network and to improve the quality of the water supplied to the consumers.

The utility is expected to bring in 90% network efficiency by 2018, which can lead to around 50% reduction of the quantity of water lost by SEPG.

As a part of the project, the company will install 1,500 acoustic sensors across the 1,000km network to detect leaks in real time.

The firm will also install 30 probes to measure and monitor the physical and chemical properties of the water supplied to the consumers.

Water network will also be equipped with three optical bacteria detectors at key points to ensure optimum quality of water supply.

The service data collected via sensors, probes and monitoring of ongoing operations will be transmitted to the Aqua 360 control centre located within the premises of the local authority, Suez informed.

The control centre will facilitate easy and any-time access to offer an integrated and real-time view of the local water service across the network.

Local authority is likely to set up a steering committee to monitor the execution of the contract and to define its directives. It will later be followed by a thorough assessment of operations in terms of continuity of service, improvement of assets, quality of the water supply, customer satisfaction and the environmental impact of the service.

Remote reading of the water data will help in identification of abnormal water consumption in the area. Suez will also operate an Aquabus mobile customer service vehicle in the SEPG localities for one half-day each week to offer doorstep service for users.

SEPG also intends to check the possibility of using decarbonation technology for water treatment, which is likely to be validated by April 2015.
