Anticipating a 'crisis situation' in Delhi, the Aam Aadmi Party (AAP) government has asked Haryana to restore supply of raw water that is released through the Munak canal.
Haryana supplies water to treatment plants in Delhi through the canal which caters largely to areas of west and south Delhi such as Dwarka.
Delhi chief minister Arvind Kejriwal has written to Haryana's chief minister ML Khattar asking him to take immediate action.
This move of the government comes a day after it announced that 20,000 litres of free water will be provided to households in the Capital.
"Raw water released by Haryana Irrigation Department in the Munak carrier lined channel have suddenly been reduced substantially leading to major disruption in production of drinking water supply at the water treatment plants of Delhi," Kejriwal has written in his letter to Khattar.
The letter further states that despite repeated requests by the Delhi Jal Board (DJB), Haryana has not restored the supply.
"With the summer season drawing closer, the continued reduction in supply is bound to lead to a crisis situation in Delhi," reads the letter.
Seeking to resolve the issue Kejriwal has also sought an appointment from Khattar to discuss the issue with his team of officer.
In December last year, the Delhi high court had asked Haryana to start releasing water in the 102-km concretised canal - instead of the existing kuchha waterways - to check huge waste of water due to seepage.
Haryana had been refusing to switch to the new channel because of Delhi's demand that savings - in addition to the regular supply - should also come to it. However, it had started the supply after the court's intervention.
