I have consumed about 16m³ after four months of living in the house and previous construction history (I did not take a reading when moving in) (three people). So we are far from 150m³ per year. There is also a monthly basic fee of €15 for drinking water and €7.50 for wastewater. So I mostly pay the basic fee
Wow, hats off! And that with 7 days and 3 people! Didn’t you have a construction management that took a reading during handover? They should document that in your interest, right? But in the end, thrifty! Our environment thanks you!!
