In the context of some of these innovations, public funds could be used in order to leverage market-based repayable financing so as to increase the overall amounts of finance available to the sector. In the water sector, this has been done at the level of specific projects, like in Maputo (Mozambique) for the financing of the urban water and sanitation program or via the establishment of financing vehicles, which aim to combine diverse sources of finance (such as in FINDETER in Colombia, a public-private financing entity which rediscounts commercial bank loans for local infrastructure development, including water and sanitation). Such blending can take many forms: ODA grants can be provided as interest rate subsidies, seed financing for revolving funds or contributions to the establishment of project preparation facilities. The main objectives of blending are to attract funds that would otherwise not be attracted by a given project while ensuring that basic public policy goals, such as increasing access and serving the poor, are met.
