2.6 billion people on this planet do not have access to a proper toilet. Each day hundreds of children are dying underage due to fecal-oral-transmitted diseases. The iPiT team tries to contribute to find solutions for the worldwide sanitary crisis by addressing the main objectives in their pilot project in Darkhan within the frame of the MoMo project.

The iPiT is a key component of an integrated sanitation system. Therefore, it is specifically designed to match the specific needs of the overall system. The toilet and the containers have to function as a unit. Urine and feces are separately collected in 2 different containers. Replaceable, stackable and easily transportable containers are crucial components of the toilet.

Through separate collection of urine and feces it is possible to apply the most suitable way of treatment (biogas digester and composting) and value added reuse of nutrient-rich fertilizer in agriculture. The production of energy and fertilizer shall contribute to the economic sustainability of the system.

Another very important criteria in the development process of the iPiT is the enhancement of the user comfort. The toilet should as well be safer and easier to use for children and elderly people. Most of the old latrines have wooden boards over the cesspit and in wintertime (with temperatures down to minus 40°C), these are very dangerous to use. Additionally the old latrines are very unhygienic, contaminate the soil and the groundwater and are therefore the main reason for the spread of fecal-oral transmitted diseases.

The iPiT is one main component of the integrated sanitation system with following research objectives:

• development of the iPiT as part of the integrated sanitation system, which is suitable for a large scale implementation in Mongolia
• emerge business opportunities for local services which include iPiT production, collection, transport and treatment of the organic matter
• identification of the potential for optimization in terms of acceptance, comfort and maintenance of the toilet technology
• identification of the potential for optimization of the integrated sanitation system in terms of material flows, energy flows and cash flows

From the beginning of the project the families, which use the toilets and other stakeholders were integrated in the whole planning process. Capacity development for all stakeholders is essential for the acceptance of the new toilet system.

Preliminary results:

• children stop open defecation and start to use the new toilets
• improvement of hygiene - toilet user keep their toilets clean
• high demand for the iPiT among neighbors and guests
• high level of acceptance
• demand for fertilizer made from urine and feces is increasing significantly
