Book a visit or order brochures
We organise guided tours of the Viikinmäki wastewater treatment plant and Vanhakaupunki water treatment plant. You may book a visit via the links on the left.
The Viikinmäki wastewater treatment plant welcomes various groups of visitors (e.g., educational institutions, associations, organisations, companies). At Viikinmäki, we also organise student visits for upper comprehensive school grades 7 and up and students in secondary education. For safety reasons, we cannot arrange visits at the plant for schoolchildren younger than 7th graders.
At the Vanhakaupunki water treatment plant, we organise tours for water management students, other expert groups and journalists. The water treatment plant does not offer visits for students in upper comprehensive schools or secondary education.
The visits are not suitable for the physically handicapped. The maximum size of a group is 25 persons.
The visits are free of charge for schools, water management students and, for example, Helsinki-based associations.
The price for company visits is EUR 350 + VAT 24%.
