Sabah Water Bill Calculator: How Many Blue Tanks Did You Use?
Type in your Sabah water bill and see your water as the blue rooftop tanks we all know. It works with the official Sabah Water Department (JANS) rates for houses, flats, shops and more, and shows how your household compares with the Malaysian average.

Estimates from the published JANS rates (checked 20 October 2026), assuming each band is charged at its own rate. We have not yet matched it line by line against a printed bill. If your bill doesn’t match, use “Report outdated info” below and we’ll fix it. The leak check appears when a home uses more than 1.5 times the Malaysian average; that cut-off is our own rule of thumb. Habit figures for pail baths, pour flushes, hand washing, drinking, mopping, plants and washing a car with pails are our own rough estimates. The hose car-wash figure is worked out from Awer’s estimate that a pail saves more than 224 litres compared with a hose (The Star, 27 August 2026).
Water bill FAQ
Q How much does water cost in Sabah?
For a house with its own meter (Domestic 1), the Sabah Water Department lists five bands: RM0.30 per m³ for 0–10 m³, RM0.60 for 11–20 m³, RM1.10 for 21–35 m³, RM1.30 for 36–60 m³ and RM1.80 above 60 m³, with a RM3.00 minimum charge (Sabah Water Department water tariff, checked 20 October 2026). The tariff page does not say how the bands add up; this calculator assumes each band is charged at its own rate, like the SESB electricity tariff. One m³ is 1,000 litres. Condos and flats on a shared bulk meter pay a flat rate instead: RM1.30 per m³ with facilities, RM0.90 without.
Q Why does a RM3 bill show "up to 10,000 litres"?
At RM0.30 per m³, the first 10 m³ cost exactly RM3.00, the same as the minimum charge. So any bill of RM3.00 could mean you used anything from nothing to 10,000 litres. The calculator shows "up to" in that case. Use your meter readings for an exact figure.
Q How big is a 400-gallon water tank in litres?
Malaysian tanks are sold in imperial gallons (4.546 litres), so a 400-gallon tank holds about 1,818 litres. Shops often sell a tank by a bigger "nominal" size than it usefully holds: one maker lists its 500-gallon tank as 400 gallons effective (Mui Fatt tank specs, checked 18 October 2026). Not sure of yours? Pick "Measure my own tank" and type in its height and widths.
Q How much water does a person use a day in Malaysia?
About 237 litres per person per day at home in 2022, according to the national water regulator SPAN (Malay Mail, 8 December 2023). This is the national figure, not a Sabah-only one. If your household is well above it, the calculator suggests a simple overnight meter check for leaks.
