Drainage

Beneath many cities lies a hidden network of brick and stone passageways built to manage water flow and sanitation during rapid urban growth. These underground drains and irrigation systems represent some of the earliest forms of organized infrastructure, designed with remarkable craftsmanship and endurance. Over time, they have become forgotten spaces, echoing with the weight of history beneath modern streets and skylines. Walking above them, most people remain unaware of the intricate world just below that once carried the vital currents of the city and still quietly supports it today.
