Supplying drinking water

In France, around 25% of drinking water produced is lost as a result of pipeline leakages. The way to reduce the volume of leakage is to optimise pipeline management. The diagnostic, maintenance and renewal techniques involved are complex, requiring sophisticated hydraulic modelling systems and the incorporation of many technical, demographic, financial and geological parameters. Saur supports and assists local authorities in forecasting, scheduling and designing projects to upgrade or renew their pipeline systems.

Pipeline system modelling

In the quest to reduce leaks and energy costs, pipeline system modelling provides an effective way of optimising operating methods, validating structural and sectorisation changes, and forecasting network sizing requirements.

Renewing pipelines

Optimising remediation programmes on the basis of the constraints and priorities specific to individual local authorities has the following goals:

  • to limit damage by reducing and stabilising failure rates
  • to improve service quality in terms of service continuity, reduced water losses and protecting living conditions.

As part of identifying renewal priorities more effectively, Saur has developed a decision support system called Patrimonia, which uses and analyses data generated by our information systems :

  • geographic data
  • pipeline system data (material, diameter, date laid, surrounding environment, etc.)
  • Operational and event data (pipeline failure, type of failure, lack of pressure, water quality, etc.)

This method is based on studying the criticality of individual sections of the pipeline system. Pipelines are categorised on the basis of the risks they pose to water supply: suspension of service, volumes of water lost as a result of pipeline failure and deterioration in the quality of water supplied. On completion of the diagnostic phase, Patrimonia generates a report that includes :

  • service improvement or deterioration forecasts based on priorities and capital expenditure budgets
  • data enabling the local authority to identify its short-, medium- and long-term capital expenditure priorities
  • recommended programmes of work scheduled over several years

Optimising pipeline system efficiency through remote metering

Saur offers a remote metering service designed to provide daily monitoring of consumption.

By detecting day-to-day consumption issues, our  remote management system can optimise pipeline system efficiency by reducing the amount of water wasted as a result of undetected leaks in connections or in the pipeline system itself.

The local authority can then :

  • target its pipeline system capital expenditure budget
  • reduce its water bill
  • control the development of its production resources
  • offer subscribers the benefit of remote metering and continual monitoring of their consumption to avoid the need to compensate consumers in the event of leaks.
