Nature of the work

A water service interruption in low- and high-pressure water mains is required for the commissioning of new water mains as part of the reconstruction of the water supply system.


Colour of the water: The interruption and resumption of water service could cause the water to become reddish in colour. This colour does not pose a health risk.

What to do in case of reddish water

Reddish water may cause certain inconveniences, such as stains on fabrics that have been washed. To avoid any damage, the municipal administration advises residents to check the water colour before using the washing machine or any other appliance that uses water. If the water is reddish in colour, let the cold water run for a few minutes until it is clear again.
