One of the most quoted WASH statistics was recently “downgraded”. For every $1 invested in water and sanitation, not $8 but “only” $4 is returned in economic returns through increased productivity. This recalculation, says WHO, is mainly a result of higher investment cost estimates and the more complete inclusion of operation and maintenance (O&M) costs. Providing a better insight into O&M costs has been one of the achievements of the WASHCost project.
