The objective of this collaborative project with Helvetas Swiss Intercooperation is to improve access to potable water in remote rural areas of Mid-Western Nepal.
This collaborative project with Winrock International will assess the impact of Multiple-use Water Services (MUS) projects in Burkina Faso and Tanzania.
