Ningsih, 12, smiles widely. The shy girl from Mangu village, Baiya sub-district, North Palu, no longer hesitates. Now, she can take a bath twice a day with clean water drenching in her skin, just like another child. Every day, after going back home from school, she always helps her family to carry water from clean water tank using plastic bottles to her home's water container. Ningsih fills the container with the carried water until it is totally filled.
