On Wednesday 11 November and Thursday 12 November, Trosa Municipality’s water and wastewater department will carry out a scheduled technical upgrade on one of the municipality’s water supply systems. Work begins on Wednesday morning and is expected to wrap up on Thursday afternoon, aimed at improving long-term operational reliability.

According to the municipality, preparatory measures are in place to maintain normal water delivery throughout the maintenance window, and the assessment is that tap water will keep flowing without interruption. The notice does not announce a planned water shut-off.

Because unexpected pressure drops or brief disruptions can still occur during system upgrades, Trosa Municipality advises households to fill containers with drinking water in advance as a precaution for the two-day period. The municipal notice does not specify which individual streets or districts belong to the affected water system.
