“Lessons in Every Drop” focuses on the role of education in shaping public awareness about sanitation, health, and civic responsibility from the late 1800s to the present. The exhibition brings together textbooks, posters, and classroom materials used to teach students about the Carriedo Waterworks and the importance of clean water.

Archival photographs show how early schools integrated hygiene lessons, while oral histories capture how teachers linked public health to the well-being of communities. A section highlights the work of Filipino women educators, who were instrumental in spreading knowledge about water safety and disease prevention.

Interactive displays allow visitors to flip through digital versions of rare schoolbooks, while younger audiences can try simplified versions of historical classroom exercises. The exhibition closes by comparing past campaigns on handwashing and sanitation with modern initiatives, including pandemic-era public health messaging. By connecting education and water, “Lessons in Every Drop” demonstrates how infrastructure is also a lesson in citizenship.
