One study estimates that funding for water and sanitation infrastructure is lacking by US$115 million a year in Sub-Saharan countries. (Africa Infrastructure Country Diagnostic (AICD) Study), while WHO gives a global estimate of $535 billion needed in new capital investment to reach universal access, or $26.75 billion per year between 2010 and 2030. (Hutton, WHO, 2012)
