One in three...

2.3 billion people in the world do not have access to adequate sanitation, one in three of the world's population.
((WHO/UNICEF Joint Monitoring Programme (JMP) Report 2015 update)

For every $1 invested in water and sanitation, an average of at least $4 is returned in increased productivity. (Hutton, Global costs and benefits of drinking-water supply and sanitation interventions to reach the MDG target and universal coverage, WHO, Geneva, 2012: page 4)

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.
