Understanding Your KWSB Water Bill

A water bill contains technical billing terms that are useful to understand. Below is a detailed breakdown of the key elements found on a standard Karachi Water and Sewerage Corporation bill:

Consumer / Customer ID

A unique numeric identifier assigned to your property connection. This number is required for all online checks, payments and official correspondence.

Tariff Category & Plot Size

KWSC categorizes connections into Domestic (Residential), Commercial, Bulk, and Industrial. Residential unmetered bills depend on plot area (e.g., 120 sq. yds, 240 sq. yds, 400 sq. yds, or 1000 sq. yds).

Water Supply Charges

The base fee calculated for pipeline water supply. Metered commercial properties pay based on volume (per cubic meter), while residential unmetered plots pay a fixed rate per category.

Sewerage Surcharge

Karachi – a fee based on percentage to cover the maintenance of underground drainage lines, main trunk sewers and sewage treatment plants.

Arrears (old Dues)

Amounts unpaid from the previous billing cycles. If you have made the final payment and your arrears are still showing then save your payment receipt for reconciliation.

Payment deadline & surcharge

The date your payment is due. If you pay after the due date , you incur a late payment surcharge which is added to the next bill cycle.

How Karachi calculates KWSB water bills?

Knowing how your water bill is calculated will help you quickly identify billing errors. KWSB / KWSC in Karachi has two major billing structures:

1. Residential Unmetered Connections (Plot Size Tariff)

Most of the residential houses and apartments of Karachi are running on unmetered basis. The bill is not based on the actual water consumption but on the actual physical size of the plot and the number of storeys/floors of the property:

  • Small Residential Plots (Up to 120 Sq. Yds): Fixed base rate at low level to make water available for small families.
  • Medium Residential Plots (200 - 400 Sq. Yds): Moderate rate structure adjusted according to covered area.
  • Large Residential Plots (500 - 2000 Sq. Yds & Bungalows): Larger capacities for water use have higher base rates.
  • Multi-Story Apartments: Charged per unit, or via a central bulk commercial/residential combo run by the building's union.
2. Commercial, Industrial and Bulk Metered Connections

Water flow meters are used for billing commercial establishments, factories, shopping malls and large residential complexes. The charges are based on the cubic meters or thousand gallons used :

  • Base Volumetric Rate: Multiplied by actual volumetric water consumption.
  • Sewerage Maintenance Charge: (15% to 20% of base water charge)
  • Conservancy & Environmental Levies: As applicable as per local municipal laws.
