SIARE, opportunity study on skills management for sanitation, aquatic environments and flood risks

Missions

Assess the existing state of sanitation in the area:

  • Evaluate operations and equipment
  • Diagnose the technical, economic and financial organization of public services for sanitation, rainwater, flood-risk management and aquatic environmental protection in each of the local areas served by SIARE
  • Conduct a SWOT analysis (strengths, weaknesses, opportunities and threats)

Determine the potential for extending SIARE’s scope

  • Understand the legal ramifications of aquatic environment and flood-risk management, and the possible inclusion of rainwater in this area of responsibility
  • Analyse the potential advantages and disadvantages of transferring each area of responsibility: for each local area concerned, for users and for meeting the regulatory objectives

French public service management is fast changing with the adoption of the “MAPTAM” Law of January 17, 2014 and the “NOTRe” Law of August 7, 2015. The resulting reorganization has led to mergers and expansions of the local authorities for the area covered by SIARE, the sanitation consortium in the Enghien-les-Bains area.

Water and sanitation assignments must meet regulatory objectves, such as the directive on urban wastewater (DERU), the water framework directive, the law on water and aquatic environments, the master plan for water development and management (SDAGE) and the flood risk management plan (PGRI). However, the expected outcomes rely largely on technical issues such as hydrology, geology and hydraulics that go beyond administrative boundaries.

In this context of newly allocated responsibilities (e.g. aquatic environment and flood risk management), SIARE wanted to study the benefits of taking on new assignments and the best ways of pooling resources in line with its overall objectives.

Challenges

On May 31, 2016, violent storms impacted the area, causing floods by surface runoff and overflowing drains. SIARE’s networks did not overflow but the Corbon stream became a torrent. The event caused material damage and public concern, highlighting the need to quickly set up effective acquatic environmental and flood-risk management.
