In 2021, United Hands Relief aimed to fulfill its Sustainable Development Goal of providing safe and clean water by digging and establishing seventeen main water wells and installing seventeen purification units providing a sustainable source of safe water to the most vulnerable and in-need places across Gaza, such as hospitals, schools, and poor neighborhoods. The neighborhoods in which the wells were constructed are Bait Lahya, Bait-Hanoon, Khan Younis, Rafah-Iskanabiad, Al-Zawayda, Al-Qarara and Al-Bureig.
