WASHCost, a five-year initiative funded by the Bill and Melinda Gates Foundation, is focused on exploring and sharing an understanding of the true costs of sustainable services. Since 2008, WASHCost has developed new methodologies to better understand and use the costs of providing water, sanitation and hygiene services to rural and peri-urban communities in Ghana, Burkina-Faso, Mozambique and India (Andhra Pradesh).
