About water bill calculator
Municipal water bills usually combine a rate per kilolitre (1,000 litres), a fixed charge and a sewerage charge.
Formula
Bill = kilolitres used × rate + fixed charge + sewerage (often a percentage of the water charge). A family using 15 kl at ₹10 per kl with a ₹100 fixed charge and 30% sewerage pays 150 + 100 + 45 = ₹295.
Saving water
- Fix leaking taps and toilet cisterns. A dripping tap can waste thousands of litres a month.
- Use a bucket rather than a running shower or hose.
- Run washing machines with full loads.
A worked example
A family of four using about 135 litres per person per day uses 540 litres a day, or 16.2 kilolitres a month. At ₹8 per kilolitre that is about ₹130 for the water, before any fixed or sewerage charges.
Where the water goes
- Bathing and toilets use the largest share in most homes.
- A leaking tap can waste hundreds of litres a month.
- Metering and tiered rates push households to save.
