Want to help breaking the
cycle of suppressed demand & Invest now!

We have already distributed over 450,000 cookstoves + water filters to the poorest 30% of families in Rwanda, touching the lives of over 1.5 million Rwandans.

We follow Sustainable Development Goals (SDGs)

Social & Environmental.

• Proven health impact: reduced child morbidity, mortality and significantly improved health through reduction of waterborne diseases and smoke inhalation.

• Overcoming traditional ‘suppressed demand’ barriers: low incomes are mitigated through
giving the devices away for free and challenges surrounding poor infrastructure are eased by the Rwandan Government providing logistics.

• Positive carbon footprint: reduced deforestation and CER generation.

• Strong gender angle: Empowering women and children to become educated through reduced time taken to collect firewood and water ultimately allowing them to make a greater financial contribution to society.

Economic & Commercial.

• Productivity & output: a healthier, more gender balanced, workforce increases GDP.

• Education & employment: implementation and training programs, future maintenance and manufacturing contracts.

• Commercial returns: aligned project impact with the ability to organically grow exponentially through the creation of a virtuous cycle of sustainability.

The impact of project Tubeho Neza

Inadequate and unsafe drinking water is the leading cause of diarrheal disease, which alone accounts for more than 500,000 deaths annually in children under 5 years in low-income countries (Pruss 2014).


Environmental contamination at the household level is a major cause of death and disease, particularly among rural populations in low-income countries. Household air pollution (HAP) contributes to acute lower respiratory infection (ALRI), the leading cause of death in children under 5; among adults, HAP is a risk factor for ischaemic heart disease, stroke, hypertension, chronic obstructive pulmonary disease, lung cancer, trachea, bronchus, cerebrovascular disease and cataracts (Gordon 2014; Smith 2014; Clark & Peel 2014).

Collectively, pneumonia and diarrhoea are responsible for an estimated 6.9 million deaths annually (The Lancet Diarrhoea and Pneumonia Interventions Study Group 2012). In Rwanda, 99.0% of rural householders cook with biomass, mainly on open three-stone fires, and only 2.2% have water on their premises (Rwanda DHS).


The intervention consists of the free distribution of cookstoves and water filters and the continued monitoring and promotion of their use. The cookstove is the EcoZoomTM Dura, a “rocket stove” that concentrates the combustion process while channeling airflow to more completely burn the combustible fuel provided.

28 in cookstove emission
50 percent reduction of diarrhea
73 percent reduction in household pollution for families cooking

The water filter is the Vestergaard Frandsen Lifestraw FamilyTM 2.0, a point-of-use microbial water treatment system designed for household use in resource-limited settings. The unit treats up to 18,000 liters of water, which can supply a family of five with clean drinking water for three to five years, and exceeds the World Health Organization’s (WHO) “highly protective” standard for household water treatment technologies (Clasen 2009). The intervention is promoted by initial and regular follow-up visits by community health workers (CHWs) hired by the MOH that are trained and compensated for their time on the project by the implementer.
