Pedro Friedeberg (1936-2026)— A Tribute to Drainage [acrylic paint. ink, cardboard, on panel, 1976]

The Indus Valley Civilization had one of the world’s earliest urban sanitation systems over 4,000 years ago. In cities like Harappa and Mohenjo-daro, many homes had bathroom areas and water-washed latrines connected to covered street drains.

We often rely on water draining through beds of grains, whether it's the soil foundation beneath a building or the sand-and-gravel-filter used in water treatment. But how does water move through these tortuous porous passages? (Video and image credit: J. Choi et al.)
