The Brackwede open-air pools have been a significant landmark of the city of Bielefeld and part of locals' life since 1926. After several renovations since its opening, in 2005, the maintaining company of the Brackwede open-air pools proposed to convert the pools into natural-water bodies through the application of natural water filtration systems. The pools are supplied from the natural underground stream of Ems-Lutter whose spring water is physically and biologically purified by natural mineral soil filter and water plants. Chlorine is prohibited in this pool - the nature itself ensures water quality (1). Since 2009, the Natural pool of Brackwede offers natural facilities for swimming and other water-related activities besides cultural, sport and recreational opportunities for all (1).
