Domboshawa Primary School is over 100 years old, and is a small school perched on a large granite hill in Morozva, Zimbabwe. With no immediate access to water, students have to walk to the nearest natural spring to collect water.
"The real problem is that the spring is unprotected” says Jonathon, the vice principal. “The cattle drink here and the people do their washing here. If a waterborne disease was to infect this water source, it could wipe out 3/4 of the school."
