The Drains Beneath Mohenjo-daro

In the ancient city now called Mohenjo-daro, streets followed an organized layout and many buildings were made from standardized baked bricks. Archaeologists have also found numerous wells, bathing areas, and covered drains. Wastewater could move from some houses into channels along the streets.

These features reveal careful planning and repeated maintenance. Brick covers allowed sections of drain to be opened, while settling spaces could catch solid material before it blocked a channel. Water management was not confined to a single palace. Its structures appeared through residential parts of the city.

The remains, however, do not answer every social question. Similar brick sizes suggest shared standards, but they do not identify the officials or craftspeople who set them. A large bathing structure shows organized construction, yet its exact ceremonies or rules remain uncertain. Drains demonstrate capacity; they do not by themselves prove that every resident received equal service.

Mohenjo-daro belonged to the Indus civilization, whose script has not been securely deciphered. Without readable administrative records, buildings carry much of the evidence. The city's waterworks show technical coordination and daily concern with water, while their silences remind us to separate what ruins support from what we merely expect them to say.
