Corrective Measures

We ensure that your drinking water installation functions safely and optimally. Although most installations are well designed and maintained, situations may arise where adjustments are necessary.

Essential modifications to the water installation

Adjustments are essential when parts of the installation are rarely used. Unused pipe sections and outlets pose a risk, as legionella and other microorganisms can develop there. Timely and corrective measures to the water installation minimize these risks.

Corrective measures help prevent legionella and reduce the number of control measures and associated costs. In this way, your drinking water installation remains safe and efficient, without unnecessary additional expenses.
