Salva is sitting at the family computer after a long day of studies.He opens his e-mail ans to his surprise, he sees a message from a cousin of his in which he barely knows. The e-mail said that his father was at United Nations clinic recovering and getting a stomach surgery. Salva is now very happy that his father is alive and starts making plans toi visit him.
While Salva is visiting his father, he is learning that the contaminated water in which his father had been drinking for years, had left his father's digestive system riddled with guinea worms. An idea had come to Salva about what he might be able to do to help the people of Sudan,so he worked on it with his new family's friend. After years of speaking in front hundreds of people in churches,civic organizations, and schools, Salva finally completes his plan.
Because of Salva's father's condition, Salva is building wells to make clean water for the Dinka tribe. Not only the Dinka tribe needs water, but the Nuer tribe too. Salva decides that he will provide the Nuer tripe water through the wells as he had planned to do for the Dinka.
