Dhaka WASA Water Bill Calculator
Calculate your monthly Dhaka WASA water and sewerage bills. Estimate costs using official tariff rates, connection categories, septic/sewerage surcharges, and VAT.
Step-by-Step
- 1Choose your connection category (Residential vs Commercial).
- 2Select your measurement unit (Units/KL, Litres, or Gallons).
- 3Enter your total consumption from your meter reading.
- 4Specify if your building is connected to the WASA sewer system.
Official Tariffs
Residential = ৳ 16.61 / KL
Commercial = ৳ 46.62 / KL
Sewerage = 100% of Water Charge
Govt VAT = 5% on subtotal
KL = Kilolitre (1,000 Litres or 1 Unit on WASA meters).
Sewerage Fee
Dhaka WASA charges a sewerage connection surcharge equal to 100% of your total water bill if your property uses the WASA underground sewer system. If you utilize a local septic tank, you only pay the water consumption charge.
Understanding Your WASA Meter Reading
WASA meters have dials showing numbers in black and red. The black numbers show full cubic meters (1 m³ = 1 Unit = 1,000 Litres), which are used for billing. The red numbers measure fractional amounts in litres and decilitres, which are useful for leak detection but are not counted in monthly bills.

WASA Water Conservation Tips
- 1Check your WASA bill paper to see if you are billed for 'Sewerage' (সুয়ারেজ) before calculating
- 2WASA rates are based on Kilolitres (KL) — 1 KL is exactly 1,000 Litres or 1 Unit on your meter
- 3Regularly inspect your toilets and underground reservoirs for leaks to avoid high WASA bills
- 4Commercial rates are nearly three times higher than residential rates — ensure your building classification is correct
- 5Pay your utility bills on time through authorized banks or mobile financial services (bKash, Nagad) to avoid late fee penalties
