The Telugu Ganga project is a joint water supply scheme implemented in 1980s by the then Andhra Pradesh chief minister N.T.Ramarao and Tamilnadu Chief minister M. G. Ramachandran to provide drinking water to Chennai city in Tamil Nadu. It is also known as the Krishna Water Supply Project, since the source of the water is the Krishna river in erstwhile 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 kilometres (252 mi), before it reaches the destination at the Poondi reservoir near Chennai.
