Update on the water authority tax assessments
In recent years, you have received your water authority tax assessment later than usual. This was due to problems with the update of our computer system in 2021. This created a backlog of assessments to be sent out. We have worked hard to resolve this. Starting with the 2025 assessment, you will once again receive 1 water authority tax assessment per year.
Apologies for the delay
We completely understand the inconvenience of receiving multiple assessments in a short period of time. The board of the regional water public authority apologises for this. They take full responsibility for the problems that arose with the introduction of the new water authority tax system.
