Sweden Water Expo

New trade fair and meeting place for the water and wastewater industry at Stockholmsmässan

Welcome to Sweden Water Expo

September 16-17, 2026

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 is now launching Sweden Water Expo, a new regional and industry-wide trade fair and meeting place for the water and wastewater sector, which will premiere on September 16-17, 2026.

There is great interest in the initiative, which is supported by several important stakeholders. First to be presented as a partner is Stockholm Vatten och Avfall, the country’s leading water and wastewater company, which welcomes the investment in a new meeting place in Stockholm and Mälardalen.

The investment needs in municipal water and wastewater facilities amount to more than SEK 500 billion by 2040 (Source: Swedish Water). Of this staggering sum, more than half is estimated to be needed for reinvestment in aged water and wastewater treatment plants and worn and damaged pipes. In the country’s fast-growing regions, extensive investments are needed.

– The region is facing major future investments in water and wastewater networks, which need to go hand in hand with skills development and innovations. Stockholm is the country’s largest water and wastewater market and with our natural proximity to decision-makers and government officials regionally and nationally, we are convinced that Sweden Water Expo will give exhibitors great commercial impact. The initiative has been preceded by interviews with more than 100 Swedish water and wastewater managers who express their strong support for a meeting place in Stockholm, says Magnus Eriksson, Business Area Manager B2B Stockholmsmässan.

– Stockholmsmässan has been a well-established organizer of trade fairs in the built environment sector for decades. For example, in just a few weeks we will open the doors to Nordbygg, the Nordic region’s leading meeting place for the construction and real estate industry, for the 22nd time. With Sweden Water Expo, we now have the pleasure of getting to know a new and natural target group, but above all the chance to deliver a sustainable meeting place that brings people, companies and society forward, completely in line with our strategy,” says Staffan Ingvarsson, CEO of Stockholmsmässan.
