ISLAMABAD: Residents in the twin cities of Rawalpindi and Islamabad are preparing for considerable interruptions in their water supply as the annual maintenance of Khanpur Dam, the main water source for both cities, is set to occur from February 10 till February 20.
The maintenance is designed to eliminate sediment accumulation and ensure optimal water flow, essential for the water distribution network serving millions in the area.

Khanpur Dam is situated around 50 kilometres from Islamabad. It has been supplying water to the twin cities since its construction in the 1980s.
It provides water for residential, agricultural and industrial purposes. However, sediment buildup over time can impare its capacity and efficiency, making its regular maintenance necessary.
Officials from the Capital Development Authority (CDA) announced that the desilting operation will cover the area from Khanpur Dam to the Sangjani filtration facility. The entire process is expected to conclude by February 23, after which normal water supply levels are expected to resume.
The CDA released an official notice outlining the specific areas that will be affected during the maintenance period.
In Islamabad, sectors that will face water shortage include D-12, G-10, G-11, F-10, F-11 and G-9.
Similarly, different neighbourhoods and colonies in Rawalpindi, such as Dhok Hasso, Ratta Amaral, Pirwadhai and Faiji Colony will also experience disruptions.
The CDA recommended that residents store water in advance and minimise their consumption during the mentioned time period.
The expected decrease in water supply is substantial, with Islamabad expected to receive 5.5 million gallons less per day, while Rawalpindi will encounter a shortfall of 13 million gallons daily.
