The Sigma Plan is a project of the Government of Flanders. Waterway manager De Vlaamse Waterweg nv coordinates the Sigma Plan and is tasked with water management. De Vlaamse Waterweg nv works together closely with Natuur en Bos (Agency for Nature and Forests) to achieve the conservation objectives.

We have also joined forces with local governments, farmers’ organisations, nature associations, the local population, hunters, anglers, the tourism industry, the hospitality industry and many other partners in our efforts to implement the Sigma Plan.
