About Project

The TAB KIT Project, currently underway in Nepal, Bangladesh, Uganda, Mexico, and Bolivia, presents a new solution for clean and sustainable water access for the local population. Despite billions of dollars invested globally, the number of people without safe water remains high. Projections estimate that by 2030, 4 billion people and by 2050, 6 billion people will face water scarcity. In many rural regions, abundant rainwater often goes unused.

TAB KIT is easily assembled from locally available materials and costs only USD 50. This stands in sharp contrast to conventional systems costing around USD 1,000 and requiring more than 100 parts. It consists of three main components, all of which can be sourced within a 15 km radius, eliminating the need for manufacturing or complex distribution networks. With this system, each household can secure 100% of its daily water needs.

The system has already reduced the time women and girls spend fetching water by about 3 hours per day, improving safety, water quality, and enabling five times more water use. It has been reported that access to clean water resulted in a number of positive outcomes, such as improved health, cost savings, small business creation, and vibrant social interaction within communities.

TAB KIT was developed through co-design with local organizations and communities. Households took part in sourcing materials, installation, and improvements. It is now in use across five countries and further aims to reach 100 million people within the next decade.
