The first known sewer system was developed by the ancient Indus Valley Civilization around 2500 BCE, particularly in the city of Mohenjo-Daro. This sophisticated system included covered drainage channels and toilets connected to a centralized sewage system, showcasing advanced urban planning for its time. Additionally, ancient Rome also made significant advancements in sewer construction, with the Cloaca Maxima, one of the world's earliest sewage systems, built around 600 BCE.
