How Water Bills Are Calculated in Pakistan's Major Cities
Pakistan's city water utilities use a metered slab system — the more cubic metres you consume, the higher the per-unit rate above each threshold. Unlike electricity, most WASAs also apply a minimum charge for low-usage months to cover fixed infrastructure costs. Here's what appears on a typical WASA bill:
Water Supply Charge
Metered consumption × the applicable slab rate. The main line item on every WASA bill. Rates vary by city and are reviewed by provincial governments.
Sewerage & Sanitation
A fixed percentage or flat charge for wastewater collection and treatment. Applied on top of the water supply charge in all major cities.
Meter Rent
A small monthly charge for maintaining the water meter. Some WASAs bundle this into the connection fee while others bill it separately.
Arrears & GST
Any unpaid prior-month amounts are added to the current bill. 17% GST applies to commercial water connections; domestic connections may be partially or fully exempt.
