Stockholm and Mälardalen are home to half of Sweden’s population and growth is expected to continue at a rapid pace. Being able to deliver a robust and reliable water and wastewater infrastructure in the region will be key to sustainable and safe development. Future new and reinvestment in the water and wastewater networks is therefore expected to be extensive, while community development needs to involve many different actors. To meet these needs, Stockholmsmässan has developed Sweden Water Expo, a new regional and industry-wide trade fair and meeting place for the water and wastewater sector.
