This case study reports design and construction of UDDTs at 3 primary boarding schools (with up to 210 pupils each) in rural Gujarat, India. The “compost” (i.e. desiccated faeces and cover material) and urine are applied as soil conditioner and nitrogen-rich liquid fertilizer to flower beds, kitchen gardens, etc.

This case study reports pilot-scale implementation of UDDTs for eight households in Arusha, Tanzania. The UDDT technology was adopted from the NGO EEPCO (Environmental Engineering and Pollution Control Organization), and chosen due to the fact that the structure is permanent and there is the possibility of using the products from the toilet for local agriculture. Urine is used at the farms around the households as fertilizer.

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.
