Hello teacher! 

Oulu Waterworks provides PowerPoint slide shows for schools which could be helpful when teaching about water. Most of the slide shows are in Finnish, but one can be found below in English. The slide show is designed for middle school and upper secondary school students. 

As a part of the Oulun Päivät event, Oulu Waterworks offers a chance to tour the Puolivälinkangas water tower or the Taskila sewage treatment plant. The Oulun Päivät event takes place each year in September.
