When archaeologists discovered the 5,000-year-old site of Mohenjo Daro in Pakistan, they found that the city demonstrated an exceptional level of civic planning and amenities. The houses were furnished with brick-built bathrooms and many had toilets. Wastewater from these was led into well-built brick sewers that ran along the center of the streets, covered with bricks or stone slabs. Cisterns and wells finely constructed of wedge-shaped bricks held public supplies of drinking water.
