This webinar will introduce the potential for UV to play a role in water treatment in low- and middle-income countries and support meeting UN Sustainable Development Goal 6 through improved water service delivery and quality via disinfection. The speakers will discuss the current state of water quality and treatment world-wide and provide case studies of UV applications, successes, and challenges in practice, as well as the promise of UV for future water quality improvement. A discussion open to all webinar attendees will be held to gather perspectives on considerations for the effective use of UV technologies in low resource settings.
