Water supply to parts of Delhi and some districts of Uttar Pradesh is likely to be affected following the closure of Ganga canal for maintenance from October 17.
"The annual repair works will be carried out from October 17 to November 5," Superintending Engineer Kirshan Kumar said today.
The decision to close the canal for repair work has been approved by the Uttar Pradesh government and conveyed to the Irrigation Department, he said.
The Delhi Jal Board and district authorities have been informed about it, he added.
Almost 19 districts of Uttar Pradesh including Noida, Muzaffarnagar, Meerut, Bulandshahr, Itawa, Hathras, Firozabad, Kanpur and Agra will likely be affected in their irrigation and drinking needs.
Alternative private sources like tubewells and pumping sets may be used by farmers in the areas to meet their irrigation needs during the period.
The Ganga canal also supplies water to the Sonia Vihar water treatment plant in Delhi.
