A new approach for reducing diffuse agricultural pollution in water supply ponds

Preserving the quality of raw water for drinking likely to be affected by diffuse pollution in water supply ponds (WSPs) is a major public health issue. We must therefore implement efficient and sustainable technical measures that guarantee the long-term protection of this resource. Such measures can prove to be a considerable constraint for farm managers and farm owners. It is consequently absolutely necessary that the compensation provided for is in line with these constraints. High stakes and high constraints must result in high compensation. The catchment protection perimeter tool, reviewed and enlarged to encompass up to 100% of the WSP, renewed and in-depth dialogue based on solid technical and economic studies and a new compensation method established from the principle of discounted loss capitalisation over a duration equal to the lease, are all new and promising tools to solve this essential problem for sustainable development throughout the territory and to preserve the health of its population.
