In fact, the barriers are really around capacity. By that I mean familiarity with the public-private partnership approach is uneven, particularly with municipalities that don't have a long history of infrastructure investment. There is a need for those communities to understand the nature of the model and to mirror the approach taken by other more experienced municipalities. Having the advisers they need to understand how best to procure the asset and, in fact, enter into the contractual arrangements will ensure that it will be a good deal for both governments and the private sector.
