The vibrant pink and blue pipes visible throughout Berlin serve for transporting water from construction sites to the River Spree and other canals. The necessity for pumping groundwater arises from Berlin’s swampy terrain. The colors are attributed to the respective companies behind the pipes’ production: Pollems for the pink pipes and Brechtel for the blue ones. Beyond their utilitarian function, these uniquely colored pipes have evolved into a distinctive feature of the cityscape.
