WADI is designed to treat water at the household level. A crucial point of action when it comes to preventing water-borne diseases, especially for the youngest community members under the age of five. A systematic study of various methods and strategies revealed that treatment of drinking water at home prevents 39% of diarrhea cases compared to 11% when using improved water at the source. Intervention on a household level is key for long-lasting impact. With WADI, HELIOZ is providing safe drinking water to thousands of families across India, Africa and Southeast Asia – creating high economic and environmental impact and a reduction of carbon emissions on household level.
More than 2.1 billion people worldwide have no access to clean drinking water. The consequences of that include waterborne diseases such as diarrhea and cholera. In rural areas of the Global South, innovative and sustainable solutions are needed to cope with the water crisis.
Just an example from the project implementation in Bangladesh: The coastal region of Bangladesh (Bagerhat District) is severely affected by climate change and lack of clean drinking water. Due to the low income of households in Bangladesh, families cannot afford water treatment technologies and are dependent on available resources like firewood to help with boiling water. Boiling water with firewood leads to diseases of the respiratory system and high carbon emissions. In addition, the purchase of firewood leads to a financial burden for families.
HELIOZ helps with:
- The provision of safe drinking water for 2,100 households, (more than 10,000 beneficiaries)
- The disinfection of more than 15.3 million liters of water per year
- Project area: Bangladesh
- Partner: HELIOZ & CDD Bangladesh
HELIOZ will focus on climate projects and the generation of CO2certificates for the European Market. Furthermore, HELIOZ will extend its product portfolio from a household-based solution (WADI) to a community-based solution (solar water treatment unit).
Main Target Group
Beneficiaries of HELIOZ projects with WADI are rural households in the Global South without access to clean drinking water. The implementation of those projects is financed through CSR programs or carbon credits generated through climate projects based on the WADI.
The main users of the WADI are households in rural areas of the Global South, which often depend on contaminated ground water.
