In 2003, Singapore's national water agency launched an unprecedented program to provide more than 50% of their nation's water supply by recycling wastewater. The program had been planned for decades to ensure the island nation never ran out of clean water. But is it really safe to reuse anything we flush down the toilet? Francis de los Reyes explains the science of wastewater treatment. [Directed by JodyPrody, The Animation Workshop, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].

Transforming wastewater into drinkable water involves complex processes, from microfiltration to UV disinfection, ensuring safety.

Singapore's innovative approach to water scarcity, treating and recycling wastewater for potable use, serves as a global example.

Addressing water scarcity requires both high-tech solutions for urban areas and smaller scale technology for communities without access.
