Karachi Water & Sewerage Corporation

What Karachi Water & Sewerage Corporation does

Karachi Water & Sewerage Corporation (KW&SC) is a government-owned utility corporation operating under the Government of Sindh, Pakistan, with an exclusive mandate to provide water supply and sewerage services to the Karachi metropolitan area — a catchment of approximately 30 million residents and Pakistan's largest city. Founded in 1953 as the successor to earlier municipal water schemes dating back to 1881, the corporation manages the full water cycle from raw water abstraction at Keenjhar Lake on the Indus River system, through bulk transmission via the Hub and Dhabeji Pumping Stations, to distribution across the city and downstream wastewater management. The current leadership under Managing Director/CEO Engr. Syed Salahuddin Ahmed has prioritized enforcement against illegal hydrants and connections in partnership with Pakistan Rangers Sindh, and has restructured operations into four geographic zones in 2025.

KW&SC's service portfolio comprises four core customer-facing digital modules — Complaint Management, New Connection application, Bill Generation, and Online Tanker Booking — supported by a Grievance Redressal Management (GRM) Cell and a Hydrant Management Cell. On the infrastructure side, it is executing or planning several mega-projects including the K-IV Water Supply Project Phase-I (260 MGD capacity addition), the TP-IV Wastewater Treatment Project (over $400 million), the Nabisar-Vajihar Water Supply Project ($215 million), the Dhabeji Pumping Station Rehabilitation, and the Sewerage System Overhaul for District East. International development partners include the World Bank, Asian Development Bank, and European Investment Bank (which committed €60 million in 2026 for two Karachi water filtration plants serving 2.2 million residents as part of €160 million in post-disaster reconstruction funding).

The corporation's revenue model is a hybrid of regulated tariffs on metered and bulk connections (residential, commercial, industrial), one-time new connection fees, transaction-based hydrant operations (which grew from Rs. 997.7 million to Rs. 1.66 billion between July 2022–May 2024), and tanker booking fees for unconnected areas. However, the utility faces a structural 40 MGD supply shortfall against an estimated 650 MGD daily requirement, suffers an estimated Rs. 13 billion in annual losses from illegal connections, and remains dependent on provincial government and multilateral development bank financing for capital expenditure. Pricing is not publicly disclosed and is effectively regulated.
