The main opposition Congress did not attend the audio-visual presentation, saying such a move is against standard and traditional parliamentary practices.
In the three-hour presentation, Rao sought to highlight the alleged injustice meted out to Telangana in undivided Andhra Pradesh.
He also alleged that lower riparian Telangana and AP faced a "danger" of reduced inflows with Maharashtra and Karnataka building about 450 barrages on Godavari and other rivers.
The irrigation projects of Telangana in undivided AP were designed with a conspiracy of throwing them into either inter-state disputes or environmental issues so that water reaches the non-Telangana regions, he alleged.
Observing that his government's policy is to have friendly relations with neighbouring states, Rao said the recent understanding reached by his government with Maharashtra is a case in point.
The same applied to (new) AP as well, Rao said, adding he had even told the same to Chief Minister N Chandrababu Naidu earlier.
