Households and businesses connected to the municipal water network in Visby, Lummelunda, Brissund, Själsö, Väskinde, Vibble, Västerhejde, Tofta, and Västergarn need to reduce their water usage, according to Region Gotland. The regional authority states that reducing water usage is necessary to prevent potential loss of water pressure or complete stoppage. The water issue stems from ongoing major works since winter to improve drinking water quality and reduce plankton organism levels, combined with planned annual maintenance.
These works temporarily reduce water production capacity. Region Gotland has been aware of the risk since winter and is closely monitoring water consumption. ' A temporary water treatment plant is being constructed and is expected to be operational by summer.
According to Region Gotland, the temporary water treatment plant will increase drinking water production and stabilize the situation. Until the temporary plant is operational, it is important for affected areas to conserve drinking water, and the rest of Gotland can also help by using water sparingly. se/sparavatten.
The ongoing works involve upgrades to filtration systems and infrastructure to address persistent issues with plankton blooms, which have affected water taste and safety in recent years. Region Gotland reports that current water levels in reservoirs are below seasonal averages, exacerbating the strain from reduced production. Authorities are coordinating with local businesses, especially in tourism and agriculture, to implement water-saving practices without disrupting essential services.
Historical data shows that similar conservation efforts during past droughts helped maintain network integrity, but this year's combination of maintenance and low supply presents a unique challenge. Residents are advised to limit activities like car washing, garden watering, and long showers, while industries are exploring recycling and alternative water sources. The temporary plant, once operational, is projected to boost capacity by 30%, but delays could extend the conservation period.
Region Gotland is also evaluating long-term solutions, such as desalination and enhanced rainwater harvesting, to prevent future crises. Public awareness campaigns include social media updates and community workshops to educate on sustainable water use. Monitoring systems are being enhanced to provide real-time data on consumption and network pressure, allowing for quicker adjustments if needed.
The situation underscores the broader vulnerability of island communities to water scarcity amid climate change and aging infrastructure.
