In both OECD and non-OECD countries the water sector is facing the challenges of increased competition for water resources, deteriorating water quality, and the effects of climate change and poor management. In this context, how can countries ensure access to adequate, sustainable and affordable water and sanitation services for all? Pricing water-related services is part of the answer. This report compiles data on pricing water and on water supply and sanitation services comparable across OECD countries. It sheds additional light on such policy issues as the choice of tariff structures for water services, cost recovery for water services and affordability.--Publisher's description.
