Karachi Water Supply Shutdown Set for August 3–5 During Gharo Upgrade
KARACHI: Water supply to several major parts of Karachi will remain temporarily suspended from August 3 to August 5 as the Karachi Water and Sewerage Corporation carries out a critical upgrade at the Gharo Old Pumping House. The interruption will begin at 10am on Monday and is scheduled to continue for 48 hours, ending at 10am on Wednesday.
The affected localities include Ibrahim Hyderi, Landhi, Shah Faisal Colony, PAF Base Masroor, Karsaz and nearby neighbourhoods connected to the pumping system. Residents and businesses in these areas have been advised to prepare for reduced or unavailable piped water during the maintenance period.
According to the water utility, the shutdown is necessary to complete an important phase of the Gharo pumping facility's modernisation. Technical teams will install and activate new motors and pumps while upgrading electrical and switching equipment used to operate the water distribution system.
The work also involves transferring a 1,000-kilovolt-ampere transformer, laying new power cables and bringing a modern switching arrangement into operation. Officials said these tasks require the pumping house to remain offline so engineers can complete the installation safely and integrate the new machinery with the existing network.
A spokesperson for the Karachi Water and Sewerage Corporation described the upgrade as a major step towards improving the stability, efficiency and reliability of water supply from the Gharo system. The corporation expects the new equipment to strengthen the pumping station's operational capacity and reduce the risk of recurring technical disruptions.
Chief Executive Officer Ahmed Ali Siddique has instructed the relevant departments and engineering teams to finish the work within the announced 48-hour window. Officials have been directed to avoid delays and restore supply according to schedule so that inconvenience to residents is kept to a minimum.
The planned suspension is expected to affect households, commercial establishments, hospitals and other facilities that rely on daily municipal supply. Residents may need to store sufficient water in advance and use available reserves carefully until pumping operations resume after the upgrade work is completed.
Karachi regularly faces pressure on its water distribution infrastructure because of its large population, expanding urban areas and ageing pumping and pipeline systems. Maintenance at major installations can temporarily disrupt supply across multiple districts, but officials say such upgrades are necessary to improve long-term performance and prevent larger breakdowns.
The water corporation will monitor the project throughout the shutdown period and coordinate the restoration process once testing of the new equipment is completed. Supply is expected to resume gradually after 10am on August 5, although normal pressure may take additional time to return across all affected neighbourhoods.
