Wells are important because without them we would be drinking contaminated water. with wells we can have clean water. but in Africa they have to walk 4 hours Just to get water. If we give them a well less people will get sick so no more suffering . A hand pump is a type of well it has a faucet and a handle that goes up and down when you push up and down.
Water Changes Everything.
Water catchment is when rain falls in to a pipe and gives villages water but in some parts of Africa it's rare to for rain but it's good to place it on the side of your house.
