Urine diversion low-flush toilets where installed in public toilet blocks of the Olympic park. Urine was collected for reuse and brownwater was treated in a septic tank and moving bed reactor before being transformed into compost. The aim of the system was to interlink the sanitation material flows as a water and nutrient source with the green areas of the park as a water and nutrient sink. Reduced water and energy demand as well as the substitution of fertilizer by urine and faeces-derived manure were expected advantages.
