Neolithic agriculture sprang up in the Indus Valley region around 7000 years ago, in the lower Gangetic valley around 5000 years ago. Later, in South India, agriculture spread southwards and also into Malwa around 3800 years ago According to consensus in modern genetics, anatomically modern humans first arrived on the Indian subcontinent from Africa between 73,000 and 55,000 years ago. However, the earliest known human remains in India date to 30,000 years ago. Ancient India is often called the Harappan Civilization because one of the ancient cities was called Harappa. Harappa was just one of 1500 cities in the Indus River Valley. Another well-known city is called Mohenjo-Daro. Historians estimate Ancient India to be the biggest of all four early civilizations.
In cities related with the Harappan civilisation, each drain had a gentle slope so that water could flow through it. Very often, drains in houses were connected to those in streets and smaller drains led to bigger ones. As the drains were covered, inspection holes were provided at intervals to clean them
