Briefing Note 1a - Life-cycle costs approach: costing sustainable services, November 2011
Estimating the true cost of extending sustainable WASH services to poor households is an on-going problem for WASH service providers. How can we achieve the most while spending the least? WASHCost addresses this challenge by developing and testing the life-cycle cost approach in rural and peri-urban areas of developing countries. Using the life-cycle cost approach enables service providers to consider a wider range of costs. The life-cycle cost approach compares effectively the different WASH delivery systems within a district, country or region. The approach can therefore be tailored to specific needs and critical issues in different countries.
