100% of your donation goes directly to the field. Most wells are currently being constructed in southern Nepal and Northern India. These regions are targeted areas because over 350 million people living in desperate poverty on less than $2 per day and lack clean water. Most have never heard the life changing message of Jesus Christ.
So in partnering with them, you allow a pastor to go meet a need by bringing clean water to a community (via the well) and in the process, they will build relationships and share the Living Water with them.
