Water management infrastructures are aging in developed countries and now call for renewal, whereas, in emerging countries, there is a strong demand for initial equipment.

They include, among others, water networks and storage and treatment systems. Alongside centralised systems operating through large networks, local management approaches are being developed based on systems that are more independent.

Against a background of strong international competition, equipment must be capable of achieving high performance, give good environmental results, be easy to put into operation, be capable of being integrated into global systems (sustainable towns, integrated water and energy management, etc.), be suited to local contexts and obtain the necessary approvals.

Priority areas in the field

Innovation Pathways

  • High-performance pipelines for the various types of network
  • Renovation of networks
  • Local rainwater management
  • Treatment of micro-pollutants
  • Recovery of material and energy flows from effluent

Action by HYDREOS in this field of activity is the focus of attention
of the ‘Biofilm and Scale Incrustation’ working group.

An example - the SIRENAplus project

SIRENAplus, Innovative surfaces for water networks in new urban areas and renovation of existing networks.

Water quality, from a health point of view, depends, among other things, on limiting the presence of microorganisms that often become encrusted on the inner surfaces of the pipes and are known as ‘biofilms’

Until now, only regulated use of chemical substances (chlorine and chlorine dioxide) inside the pipework of drinking water networks makes it possible to partially solve or limit these problems of microorganism deposits (biofilms).

In order to limit both the health risks and the use of treatment products, the partners of SIRENAplus, led by Veolia Environment, are proposing to act on the actual source of formation of the biofilms.

The SIRENAplus project, promoted by the HYDREOS cluster, and jointly approved by the PLASTIPOLIS and MATERALIA clusters, involves developing one or more innovative surfaces that will prevent the formation of deposits and biofilms thereby aiming to reduce and prevent the risk of deterioration of water quality. These surfaces will be factory-applied to new pipework and also retrofitted to existing pipework when it undergoes renovation work.
