While BJP state president Satish Upadhyay tersely observed that "conditions" to AAP's promises are being revealed now, Congress chief Ajay Maken said the move would put "additional burden" on common people.
Upadhyay further termed the decision as a "stab on people's back".
"It is shocking that in today's important meeting of Delhi Jal Board no proposal has come for laying new water supply line in any area of Delhi but instead the Board has come up with a proposal to buy 250 new tankers," he said.
Maken said the government had "betrayed" the trust and confidence of the people of Delhi, who had believed in the "false promises" made by the AAP before the Delhi Assembly elections, "only to regret now".
