The Syndicat Mixte de l'Aulne (SMA) plays a role in assuring the security of the drinking water supply (AEP) to the South-Western quarter of the Finistère (Brittany). It covers an area of 1300km² and includes 5 EPCI’s, which combine nearly 180,000 users, and will soon expand to a 6th EPCI. Each of these areas has its own resources and calls on the SMA for permanent supply or for ad-hoc security.
This pilot site is home to several stakeholder groups making use of the drinking water supply: agriculture (livestock), industry, a growing tourism industry, and a growing population, linked to coastalisation. These growing needs are coupled with a decrease in the availability of water resources and it is possible that the AEP networks will not be able to meet everyone’s needs in the future.
The multitude of sampling points and the collective security role of the SMA justify thinking about the sustainable management of resources in an all-round way on this pilot site, for greater efficiency.
What will we achieve?
Our approach on this pilot site is based on the development of a decision-making support tool which will allow communities to collectively optimise the use of their resources to secure the drinking water supply locally, and on the active participation of stakeholders in this area. A working group will be set up to bring out the management problems that need to be tackled collectively at a local level, identify management strategies and define how they are implemented by stakeholders.
A Collective Approach
Our approach on this pilot site is based on the development of a decision-making support tool which will allow communities to collectively optimise the use of their resources to secure the drinking water supply locally, and on the active participation of stakeholders in this area. Read More
– Building a shared vision of current issues and medium- to long-term challenges of the drinking water supply.
– Provide local communities with a compilation of data from various sources. Read More
– Initiate a collective reflection, with the creation of a reflective practice group integrating the communities responsible for the AEP service and those responsible for water management at the watershed level.
– Co-development of guidelines for the collective management of resources.
– Development of a modeling tool which supports a participatory approach, allowing the simulation of the impact of different management scenarios and providing information for collective decision-making.
