The ROSA project (ResourceOriented
Sanitation concepts for periurban
areas in Africa) proposes
resourcesoriented
sanitation concepts as a route to sustainable sanitation and to meet the UN
Millennium Development Goals. These concepts are applied in ROSA's four pilot cities in Eastern Africa:
Arba Minch in Ethiopia, Nakuru in Kenya, Arusha in Tanzania, and Kitgum in Uganda. With in the
framework of the ROSA project several pilot units have been constructed for the treatment and safe use of
human excreta, grey water and solid waste. Researches were also carried out targeting the gaps for the
implementation of these resourceoriented
sanitation solutions. In this paper the methods followed for the
construction of toilet units constructed in Arba Minh town which include UDDT (urine diversion Dry
Toilets), Fossa Alterna & Arborloo are described. In addition the implementation of the resource
oriented concepts are addressed to share the knowledge acquired while implementing these toilet units
