The Telugu Ganga project is a water supply scheme implemented in South India, to provide drinking water to Chennai city in Tamil Nadu and to provide irrigation facilities in the drought prone areas of Rayalaseema region. It is also known as the Krishna Water Supply Project, since the source of the water is the Krishna river in Andhra Pradesh. Water is drawn from the Srisailam reservoir and diverted towards Chennai through a series of inter-linked canals, over a distance of about 406 km, before it reaches the destination at the Poondi reservoir near Chennai.
