The Indus River System Authority said on Wednesday that Pakistan has wasted 800,000 acre feet of usable water since April 1.

The country lost Rs132 billion by not utilising this water over the past two and a half months, according to Irsa officials. This huge quantity of water flowed down into the Arabian Sea.

The wasting of one million acre feet water causes a loss of around $1 billion, they said.

The authority has estimated a loss of 20 million acre feet water this year due to a shortage of water reservoirs.

It says 4 million acre feet water has been rendered unusable due to sand and mud accumulation in different dams.

Irsa officials have recommended immediately establishing water reservoirs with a capacity of 20 million acre feet.
