KARACHI:
For millions of Karachi residents facing chronic water shortages, the long-awaited K-IV project was supposed to be the solution. Instead, two decades after its initial conception, the mega water project remains mired in delays, rising costs and unfinished infrastructure, with officials now saying it could still take at least three years to complete.
Top officials of the Karachi Water and Sewerage Corporation (KWSC) have admitted that at the current pace of work, the federal government’s completion target of December 2026 appears increasingly unrealistic. According to project officials and sources, the project is expected to be completed in early 2029, provided there are no further delays.
Karachi currently needs about 1.2 billion gallons of water per day, but only receives about 650 million gallons, leaving a significant supply gap. The K-IV project was designed to help bridge this deficit by bringing additional water from Keenjhar Lake to the city.
The project was officially restarted in 2014 as a joint initiative of the federal and Sindh governments, with an estimated cost of Rs25 billion. However, repeated design reviews, administrative hurdles and changing government priorities have significantly delayed progress. Today, the estimated cost of the project stands at around 224 billion rupees, with officials warning that further increases remain possible.
Sources told The Express PK Press Club that the augmentation work between Nipa Chowrangi and Hassan Square, a stretch of just 2.7 kilometers, began in November 2025 but is yet to be completed. Officials note that this is only the preliminary phase of the project, while the most difficult component – construction of the R-1, R-2 and R-3 distribution corridors – has not even begun.
More importantly, contracts for these major pipeline segments have not yet been awarded.
According to project documents, the R-1 corridor will extend for 26 km, the R-2 for approximately 40 km and the R-3 for approximately 28 km, bringing the total length of the new distribution pipelines to approximately 94 kilometers. These routes will pass through some of Karachi’s busiest urban corridors and densely populated neighborhoods.
Project sources estimate that laying the R-1, R-2 and R-3 pipelines alone will cost around Rs 80 billion. Around 80 percent of this amount is expected to be financed through loans from international financial institutions, while the Sindh government will provide the remaining 20 percent. The rest of the project – including transmission infrastructure, pumping stations, filtration plants and associated facilities – is estimated to cost around Rs 124 billion.
Under the project, the federal government is responsible for the construction of the transmission system, pumping stations and filtration facilities, while the Sindh government is responsible for land acquisition, augmentation works, power supply and irrigation-related infrastructure required to facilitate water supply to Keenjhar Lake. Officials warn that the most disruptive phase of the project is yet to come. The installation of 72- and 96-inch diameter pipelines will require extensive excavations along several major roads and arterial roads in Karachi, which could cause major traffic jams and disruptions for commuters.
One of the key routes, the R-2 Corridor, is planned to start from the Northern Bypass Toll along the Super Highway, passing through Jangal Goth, Sohrab Goth, Abul Hasan Isphahani Road, Disco Bakery, Gulshan Chowrangi, Rab Medical Center, Sir Syed University and Nipa Chowrangi, before connecting to the Augmentation Line and continuing through Hassan Square, Gharibabad, Liaquatabad, Nazimabad, Habib Bank Chowrangi and finally reach Gulbai.
Sources further claim that parts of the ongoing augmentation works have faced quality concerns from international financiers.
A senior KWSC official, speaking on condition of anonymity, said work on the city’s main water distribution network had not yet started and contracts remained pending. “If progress continues at the current pace, completion of the work by 2029 is possible. However, any further delays could push back the timetable even further.”
Once completed, the K-IV project is expected to provide an additional 250 million gallons of water per day to Karachi, increasing the total daily availability to approximately 900 million gallons. Even then, experts estimate the city could continue to face a deficit of between 300 million and 400 million gallons per day.
A senior minister in the Sindh government acknowledged that repeated design changes and escalating costs have complicated implementation, warning that several difficult stages of the project remain ahead before Karachi can finally receive the additional water it has waited decades for.
