Figure 2.1 summarises the dimensions that affect a country's capacity, and that of the sector in question, to manage increasingly complex forms of PSP (as the transfer of responsibilities and risks to the private partner rises). These dimensions have to do with the sector's financial sustainability (the extent to which the sector can ultimately cover its costs, and the role of pricing), its financing needs, and the public’s perception (in particular, its willingness to pay for service). Additional facilities are needed, including the development of new' water resources (from non-conventional sources) and water treatment plants, but the domestic network is fairly well-developed.
