The Governance of Water Regulators The establishment of dedicated regulatory bodies in charge of regulating water services whilst being recent is nevertheless a consistent trend among OECD and non OECD countries. This report presents a picture as of September 2014 of the governance arrangements operational modalities and use of regulatory tools across a sample of 34 established water regulators. It relies on the OECD Best Practice Principles for Regulatory Policy: The Governance of Regulators to structure the information collected through a survey exercise. It has been developed in close co operation with the OECD Network of Economic Regulators (NER). The results from the survey show that the 34 water regulators show generally a high level of adoption of good governance principles and practices. They display functions and powers that are in line with their objectives. Water regulators also show a strong culture of consultation. Other areas in particular evaluation of regulatory impacts could be further strengthened.
