Development banks, on the other hand, have been increasingly called upon: for example, the EBRD in Eastern and Central Europe, where commercial lending for water has been drying up, has had a boom year in 2009. Areas where ODA can have a catalysing effect include reducing bottlenecks in the sector, supporting the financial planning process, ensuring access to services by the poor and supporting the development and use of risk-management mechanisms that can help attract private funding (and local private funding in particular). While revenues from the 3Ts can dose the financing gap for WSS, the role of repayable finance is only to bridge the financing gap, since it requires subsequent compensation in the form of interests or dividends.
