Lesotho is among the poorest countries of the world. About 40% of the population survives on less than 1.25 US dollars a day.Of the nearly 2 million people in the Kingdom of Lesotho, 1.4 million do not have access to basic sanitation.

That’s 71 % of the population who have to defecate outdoors or in unsecured sanitary facilities. Diarrhoea is the most common health problem, which is associated with a high number of deaths, especially in children under the age of 12.

BORDA’s partner organisation TED (Technologies for Economic Development) is active in a variety of ways to sustainably improve the population’s situation. TED constructs decentralised wastewater treatment systems, which not only protect people and the environment, but also produce biogas that can be used for cooking or heating. As well, the treated wastewater is rich in nutrients and can be used in horticulture. TED is also active in environmental and hygiene education campaigns.


Mali is one of the poorest countries in the world with its lack of resources and impacts of climate change. Food security and the fight against poverty were the top of the political agenda before the crisis. Since 2012, about 500,000 people have fled their homes due to conflict and seek refuge in other parts of Mali or outside of the country.

BORDA is actively involved in the most affected areas in northern Mali – Timbuktu, Rharus und Dogonland.The focus is to strengthen the resilience of people and institutions from the effects and consequences of the current crisis and the violent conflict in northern Mali, as well as create new prospects for sustainable development.

BORDA implements measures for food security and sustainable agriculture, including promoting employment and restoring necessary infrastructure.

Another project focus is implementing and distributing innovative, decentralised supply systems for water, energy and wastewater treatment in the field of agricultural use. Specifically, this involves implementing and disseminating the Stirling technology. In cooperation with the local partner Centre Pere Michelle (CPM), this technology has been tested in workshops and joint seminars have been conducted to identify how it can be applied in agriculture.

South Africa

About 18 million South Africans still have no or inadequate access to basic sanitation. In addition, there is an increasing number of wastewater treatment systems, which are poorly planned and operated.

BORDA started its activities in Durban in 2006 and develops wastewater systems in unserved peri-urban areas, particularly schools and informal settlements. The focus of the work in South Africa is on applied research and the development of decentralised wastewater treatment systems. In 2010, the research and demonstration station Newlands Mashu was put into service in cooperation with the University of KwaZulu-Natal (UKZN), the Durban public utility EWS (eThekwini Water and Sanitation), and the local NGO DES (Decentralised Environmental Solutions). The facility treats wastewater from more than 80 households; and it allows researchers to study the performance of individual treatment steps. They are also conducting long-term studies on the safe use of treated wastewater to grow fruits and vegetables. The results of research will be used for the further development of the technology for decentralised wastewater treatment and will help to identify the value-adding potential for energy, water and nutrients.

As well, BORDA cooperates with Hering South Africa Engineering, a private company that produces and markets sanitary facilities and decentralised wastewater treatment systems made of prefabricated concrete for schools and informal settlements.


There are about 41 Million people living in Tanzania. The population is growing rapidly, especially in urban areas. In informal settlements, people usually have limited or no access to water, wastewater and waste management systems.In the capital Dar es Salaam, less than 20% of the more than 4.3 million citizens are connected to a wastewater system.

A lack of wastewater and waste management doesn’t only affect public health and the environment, but also the economy and the people’s livelihoods.

BORDA started its activities in Tanzania in 2007. Since 2010, BORDA’s activities in southern and eastern Africa are coordinated by the regional office in Dar es Salaam. The main focus of the work in Tanzania is developing technical solutions and business models for managing wastewater, faecal sludge and waste in cities and their outskirts. Targeted training and apprenticeship, combined with support and monitoring of local demonstration projects, aims to transfer expertise in water, wastewater and waste management. BORDA cooperates with a wide range of partners, including: the Tanzanian NGOs s (Environmental Engineering and Pollution Control Organisation) and Nipe Fagio, German GIZ (Gesellschaft für Internationale Zusammenarbeit), and the British NGO WaterAid.

Together with WaterAid in 2013, BORDA developed and constructed a faecal sludge treatment system in Kigamboni, Dar es Salaam. As well in September 2013, BORDA built the composting and recycling centre Gongolamboto and in cooperation with the district council of the suburb Ilala in Dares Salaam.


Although Zambia is politically quite stable, most of the population lives in poverty. About 50 % of the almost 13.5 million people in Zambia have no or insufficient access to sanitation. The hygienic conditions and infrastructure are far from adequate. This is accompanied by extremely high infant mortality and a low life expectancy, which is also due to the high rate of HIV infection.BORDA’s activities in Zambia started in 2007. Their aim is to supply rapidly growing poor urban areas.

The focus is on training and on-going education of professionals in wastewater management, and  technical support and monitoring of the localpublic utilities in planning, construction and operation of decentralized wastewater treatment. The infrastructure is financed through a special fund of the Zambian Devolution Trust Fund (DTF). The Zambian umbrella association WASAZA (Water and Sanitation Association of Zambia) is BORDA’s strategic partner and educational institution in collaboration with the municipal utilities. In addition, local tradespeople learn about the planning, construction and operation of high demand agricultural biogas plants.

Another focus lies in developing technical solutions and sustainable business models for collecting and treating faecal sludge from pit latrines and septic tanks. Together with the British NGO WSUP (Water & Sanitation for the Urban Poor), BORDA is working to improve wastewater management in urban areas, where the population won’t be connected to a sewerage system in the foreseeable future. One of the first projects in Lusaka’s Kanyama district went into operation in 2010.
