This OECD-report analyses selected public expenditure programmes supporting environmental investments in water supply and sanitation in four OECD countries (Austria, Belgium, France and the German New Länder) with the goal of illustrating a variety of possible institutional arrangements for the management of water sector public expenditure programmes in transition economies.

Ecologic is analysing major public expenditure programmes to support environmental infrastructure investments in water supply and wastewater management in different OECD countries of the European Union. Following their evaluation, "lessons learned" for OECD non-member countries will be drawn up. All results will be published in a study.
