Sanford (Sandy) Berg, Professor Emeritus, Economics, and Senior Fellow, Public Utility Research Center, served as one of three Peer Reviewers for the OECD’s Assessment and Recommendations for Peru’s water and sanitation services regulator, Sunass. He participated in a series of Zoom interviews over three days and reviewed the Draft Report this November. He also participated in a regulatory conference where the results of the assessment were presented. He has been monitoring Peru’s key performance indicators since 1999, so this gave him a chance to bring his experience to bear on the challenging issues facing this developing nation. Last year he participated in a similar OECD assessment of Brazil’s system of water governance.
