The Delhi government has told the Supreme Court that Haryana has not taken any concrete step to address its grievance over discharge of untreated pollutants causing rise in ammonia level in the Yamuna and release of insufficient water which led to reduction in supply in some areas here. The Aam Aadmi Party (AAP) government has filed its rejoinder affidavit in the apex court in response to the reply of Haryana and its Department of Irrigation and Water Resources. A bench headed by Chief Justice S A Bobde, on March 26, had directed the Haryana government and others to continue with the status quo on supply of Yamuna water to Delhi, making it clear that it should not be reduced to the national capital which is facing a shortage.
