SANDRE

The French Water Information System (WIS) is a mechanism created by the French state for sharing and making available public-sector water data. The WIS contains data on water resources, aquatic environments and their uses, and on public water and sanitation services, covering mainland France and its overseas departments.

The National Framework for Water Data (SNDE) sets out the objectives, scope and governance arrangements for the WIS (as enshrined in the order of 27 May 2021 amending the order of 19 October 2018 approving the national framework for data on water, aquatic environments and public water and sanitation services, and article R.131-34 of the French Environmental Code).

The SNDE is supported by a number of technical mechanisms including the French National Service for Water Data and Common Repositories Management (SANDRE), which is tasked with developing and making available the water data repository for the WIS and related information systems. The SANDRE repository is based on ISO 9001-certified quality management processes and is managed by the French Office for Biodiversity (OFB) with the support of the SANDRE Technical Secretariat, which has been entrusted to OiEau since its inception.
