EU-GTZ/SIDA EcoSan Promotion Project

Type of project:
Rural household and school based sanitation

Project period:
Start of construction: October 2008
End of operation: May 2010
Ongoing monitoring period until Nov 2010

The EcoSan Promotion Project (EPP) was a project component of the GTZ Water Sector Reform Programme in Kenya and co-funded by the European Union, SIDA and GTZ. It worked in close partnership with the Ministry of Water and Irrigation (Maji House). During the project period (November 2006 - June 2010) 804 doors of double chamber Urine Diverting Dehydrating Toilets (UDDTs) and 13 Decentralized Treatment System (DTS) were installed. Many engineers, artisans and professional companies were trained in the planning and construction of such toilets.

The project’s aim was to develop, test and promote the Ecological Sanitation concept including development of technical designs for large and small-scale sanitation projects in Kenya. The project focused on rural household and school based sanitation but also implemented toilets on public places like bus stations and institutions like prisons. In the rural areas EPP worked directly with CBOs and school authorities. Initially also a few NGOs helped in the implementation such as KWAHO and ALDEF. The EPP also worked together with the water sector institutions such as the Water Services Trust Fund (WSTF), various Water Services Boards (LVSWSB, LVNWSB, ATHI WSB, TANATHI WSB), KEWI and many Water and Sanitation Companies like NAIVAWASS in Naivasha. The WSTF will continue to fund EcoSan facilities around the country in coordination with the regional Water Services Boards and Water and sanitation companies.

Here you can see some nice pictures of UDDTs build by the EPP in Kenya:

UDDTs in schools:

The UDDTs shown above are double chamber urine diverting dehydration toilet. Faeces and urine are separated through a special plastic squatting pan.

See picture below:

The faeces are collected in chambers, where they are dried for at least 6 month while the urine is collected in a 20 liter container connected with a pipe.

The urine and the dried faeces of the UDDTs are used as fertilizer on the farms of the UDDT owner. Main crops which the products are used for are maize, bananas, kales and mangos.

For schools or public places with provision of water supply EPP promote a system of low-flush toilet that are connected to a decentralized wastewater treatment system called DEWATS where the human waste is used for production of biogas and irrigation water for agricultural production. The biogas is then used in the kitchen for cooking and helps to supplement firewood. The treated water is rich in nutrients and is used for growing all stable foods like maize, bananas, mangos and vegetables.

All toilet users were trained and educated on the use of the facility and the reuse and benefits of the human waste. Furthermore health and hygiene promotion was also included as there is a lack of awareness like handwashing after the toilet use. The monitoring and training activities will be ending in November 2010.
