Water Bill Guide
An example combines about TRY 32/m³ water and TRY 14/m³ wastewater. Municipal tiers and subscriber class change the official bill.
Two volume charges
The same measured m³ may price clean water and wastewater separately. The 32 + 14 example is a reference only.
Use the water-bill calculator for a rough total, then replace rates with your municipality’s tariff.
Some municipalities print combined lines while others split clean water and wastewater clearly. Always reconstruct both unit rates from the tariff booklet, not from a neighbour’s informal average.
Municipal tiers
Crossing a monthly threshold can move later m³ into a higher band, so average unit price is not constant. Subscriber class also matters.
If you are close to a tier edge, fixing a silent cistern leak can be worth more than waiting for the next price announcement. Track weekly m³ for one month to see whether behaviour or price is driving the bill.
Shared meters and leaks
Building allocation can diverge from individual estimates. Unexpected spikes call for index photos and leak checks via official channels.
Fixed municipal lines
Maintenance or environmental charges may sit outside a pure volume formula. Do not expect a perfect match to m³ × rate alone.
Saving near a tier edge
Fixing leaks or shifting garden watering can delay entry into a higher band. Keep summer irrigation as a separate budget line. Informational only.
Garden irrigation on sandy soil can dominate summer volume. Drip lines and morning watering reduce evaporation losses. Keep that seasonal block separate in your annual water budget.
Calculation order
Record indexes, pick subscriber class, verify both unit rates, check tiers, then add fixed lines.
Practical tips
- Photograph opening and closing indexes.
- Select the correct subscriber class.
- Enter clean water and wastewater separately.
- Check municipal tier thresholds.
- Treat calculator output as an estimate.
FAQ
Why a wastewater line?
Sewerage is often priced as a separate service on the same measured volume, using a different unit rate.
Are 32 and 14 exact?
No. They are illustrative. Municipalities and periods differ.
What is a tier?
A consumption threshold after which further m³ are billed at a higher rate, so the average price rises.
Shared meter share?
Depends on the building rules (equal split, area, etc.). Individual tool estimates may not match allocation.
Exact payable amount?
Only the water authority invoice is binding.
