Full cost recovery of water services and the 3 T's of OECD
Le recouvrement des coûts des services rendus par l'usage de l'eau et les 3 T de l'OCDE
Résumé
Considering OECD's 3 T's (tariffs, taxes and transfers) for funding water services, we show how declining water consumption triggered the 3 E's (triple bottom line) approach in the water services sector, calling in turn for new governance mechanisms for a global sustainability. We distinguish internal and external governance, each calling for new scientific approaches to support good decision making. We then develop a specific analysis of the recovery of environmental and resource costs when water services face water resources considered as common pool. In France, the liberal state tradition makes this difficult to implement, leading to incoherent water tariffs.
