How tiered billing works

Usage is charged in blocks: the first 10 m³ at the tier-1 rate, the next 10 at tier-2, and so on. Only the water inside each block pays that block's rate, which is why the breakdown lists every tier separately before adding the fixed fee.

Matching your tariff

Providers publish different tables by region and customer class. Edit the tier limits and rates to mirror your bill, add or remove tiers, and set the admin fee. The defaults are a generic example, not any real tariff.

Water Bill Calculator FAQs

Why is my estimate different from my bill?
Sewerage charges, meter fees, taxes or a different tariff class may apply. This tool covers water tiers plus one fixed fee.
What does m³ mean?
Cubic meters. 1 m³ = 1,000 liters. Your meter usually reads directly in m³.
How can I lower my bill?
Fix leaks (a dripping tap wastes liters daily), use efficient fixtures, and water gardens at cool hours.
Does it handle sewerage charges?
Not separately. Roll them into the fixed fee or a tier rate if your provider bundles them.
Is my data uploaded?
No. The calculation runs entirely in your browser.
