The Munak Canal is a 102 kilometer long aqueduct that is part of Western Yamuna Canal in Haryana and Delhi states in India. The canal conveys water from the Yamuna River at Munak regulator in Karnal district of Haryana and travels in a southerly direction via Khubru barrage and Mandora barrage, terminating at Haidarpur in Delhi. It is one of the primary sources of drinking water for Delhi. A memorandum of understanding was signed between the Haryana and Delhi governments in 1996 and the Canal was constructed by Haryana between 2003 and 2012 on payment by Delhi. Originally a porous trench, the canal was eventually cemented due to excess seepage, saving 80 million gallons of water per day.
