  • Deadlines & processing time

    What deadlines must be paid attention to?

    You must notify the local health authority of a water supply system or non-drinking water system 4 weeks before commissioning or recommissioning, construction or transfer of ownership. Structural changes must also be notified 4 weeks before the start of the measure.
