Our product

4Life Solutions’ affordable and portable drinking water purification solution, the SaWa, is tackling these challenges. The Sawa is a household water sanitizer based on Solar Water Disinfection (SODIS) that removes +99,99% of bacteria, viruses, and protozoa from drinking water and sanitizes it within 4 hours only.

What are we looking for?

Globally, 2 billion people lack access to safe drinking water, and waterborne diseases cause more deaths each year than disasters and conflicts combined. SaWa provides safe drinking water due to its fast implementable, scalable, and easy-to-use solution. The purification process emits 500 times less Co2 per year than boiling water for sanitization. Though it not only reduces CO2 emissions, but also provides access to clean water, and tackles water-born diseases and deaths. It also reduces the medical costs per household and makes extra time available, especially for women and children, which they can use for generating income and educational activities, which is impossible with current disinfection processes.


SaWa is a solution that impacts all three pillars of sustainability - societal, environmental, and economic.
