This is an estimate based on published 2026 tariff schedules. Confirm your exact rates on the printed WASA bill.
How to use
- Choose your city, connection type and billing mode.
- For unmetered billing enter your plot size in marla; for metered billing enter monthly gallons.
- Your estimated bill with water, sewerage and late-payment breakdown appears instantly.
Note: Unmetered charge = base monthly rate x plot-size multiplier. Metered charge = gallons / 1000 x rate per 1000 gallons. Sewerage surcharge applies to the water charge; late payment adds a surcharge on the total.
Tips
- Compare your estimate with the printed bill — if it differs, update the base rate in the tariff editor so future estimates stay accurate.
- Metered billing is usually cheaper for small households; ask WASA about switching if your usage is low.
- Pay before the due date to avoid the late payment surcharge.
