This Arabic online learning series is designed to strengthen the knowledge and practical skills of WASH professionals working in diverse contexts, particularly in humanitarian and low-resource settings.

The series includes three complementary courses: Chlorination in Emergencies, Household Water Treatment and Safe Storage (HWTS), and Drinking Water Quality Testing (DWQT). Together, these courses provide a foundational understanding of safe water systems and water quality management in both emergency and development settings.

Participants will gain practical knowledge on key WASH interventions, including how to ensure safe drinking water during emergencies, how to apply household-level water treatment methods, and how to assess and monitor water quality.

The courses are self-paced and accessible online, allowing learners to complete them at their own convenience. They are designed to support professional development and strengthen capacity within Arabic-speaking WASH communities globally.
