Waterless urinal sheds in the inner city, Hamburg, Germany

In 1994 the BSU (“Office for urban development and environment”) developed a general concept for the construction and maintenance of the public toilets in order to reduce annual operation and maintenance costs. All urinals installed in Hamburg’s public toilets today are waterless urinals (instead of conventional water flushed urinals which use 4-6 L per flush). In eleven urinal sheds, urine storage tanks were also installed. This urinal sheds have reduced costs than the other public urinals and it is possible, that the collected urine will be used in agriculture in the future.
