What are three effects that will occur when nyas village finally gets water

Well the effects would be more healthier people, because the water Nya gathers every day is contaminated, and o they boil it. But when they do it basically shortens the supply of water because it evaporates. And another effect is more food and a school. I've read a long walk to water, and Nya is a fictional character, but Salva tries to make the lives of sudan better, step by step.
