Water investments are lumpy and costly: financing is essential to spread the costs of these investments out over time. For water, development finance institutions still provide the bulk of such financing. It can no longer be the only one, however. The costs of extending universal access to safe water and sanitation has been estimated at US$ 114bn per year, which is a substantial increase compared to what was invested to reach the Millenium Development Goals.
In contrast, in 2014 total official development finance for water, including grants and loans with varying degrees of concessionality, reached a mere US$18 bn per year, three times more than in 2003 but still woefully insufficient to meet all investment needs. To meet the Sustainable Development Goals, governments will need to better target their investments and leverage more financing from private sources, including from households that can afford it and from commercial finance providers. — blog.wb.org/blogs
