Access to clean laundry is a fundamental yet often overlooked need in humanitarian settings, directly affecting public health and individual dignity. Recognizing this, A Drop in the Ocean (DiH), in collaboration with The Washing Machine Project (TWMP), launched a pilot intervention introducing manual washing machines at the Closed Controlled Access Centre (CCAC) on Lesvos, Greece. As we are preparing a new evaluation cycle exercise, we wanted to share these findings, which provide valuable insights into its effectiveness, the positive changes it has brought, and key lessons for future improvement.
