Where the money goes
Your bill combines fresh water, wastewater treatment and often a base fee. Municipalities set rates individually. In rentals, water usually sits inside the Nebenkosten (ancillary costs) – you pay it even if you never see a separate bill.
Saving that actually matters
Hot water is the lever: heating water costs far more than the water itself. Shorter showers and efficient shower heads beat tap-discipline by an order of magnitude.
Check your ancillary costs
Once a year, read your Nebenkosten settlement line by line – water, heating and building electricity are where errors hide.
