This was decided at a meeting of top officials of the two states held under the chairmanship of the Prime Minister's Principal Secretary, TKA Nair, in the city last month.

Haryana officials, however, said there was a water shortage in the Yamuna and the state was not in a position to supply the same amount all the time.
