solarsack

The SolarSack is a water purification system, made of co-extruded blown film in five layers, one of which is polyethylene, the others of undisclosed material that provide strength, UV resisance and UV transparency (to destroy bacterial contamination). The sack is simple to use to ensure water is safe to drink: it is filled with non-dirty water and left out in the sun (clear side up) for four hours. The purified water then needs to be used within three days. Using the SODIS (solar water disinfection) process, the innovative sack removes 99.999% bacteria, viruses and other harmful pathogens by harnessing UV-rays and heat from the sun. Designed to be easily transportable and stored, it can be re-used up to 500 times, purifying up to 2000 litres of water during its lifetime, the equivalent of providing drinking water to a family of four for one year. Costing less than $2, the SolarSack is currently in use in Uganda, Ghana, Rwanda, Kenya and Nigeria and the company have established local partnerships to recycle used sacks. Developed by Alexander Locke during a research trip to the Adjumani refugee camp in Uganda in 2017, the main intention of the SolarSack was to provide an environmentally friendly way of providing safe and clean drinking water at low cost. As an alternative method to boiling water using woodfuel, SolarSacks save carbon emissions and prevent deforestation.
