The High Court has issued an injunction asking Dhaka Water Supply and Sewerage Authority (DWASA) to not charge the new tariff till August 10.
The bench of Justice M Enayetur Rahim passed the order after a virtual hearing on the matter on Monday.
On June 15, a Supreme Court lawyer Advocate Tanvir Ahmed filed the writ with the virtual bench for public interest.
In February, the authorities once again increased the water tariff for household and commercial consumers in Dhaka, making it effective from April.
Earlier, the tariff was increased in September 2019.
Under the new tariff ceiling, residential consumers will pay Tk14.46 for each unit (1,000 litres) of water, which is Tk2.89 or 24.97% hike from the existing tariff -- Tk11.57.
On the other hand, the commercial rate has jumped by 8%, or Tk2.96, to Tk40 from Tk37.04 per unit.
According to a circular, Wasa decided to raise the water prices following government instruction in order to adjust the production cost in view of the recent hike in gas and electricity prices, and to balance out sales with production and distribution costs.
