Turning the Tide on Water Pollution: TCC-CIMET’s Innovative Solution for Safe Water

Illegal mining, popularly known as  galamsey, remains one of Ghana’s most serious environmental threats, contaminating rivers, streams, and other critical water bodies. The consequences are far-reaching: polluted water sources endanger public health, compromise livelihoods, and threaten the long-term sustainability of communities across the country. For many households, access to safe, clean water is becoming a daily struggle.

In response to this pressing challenge, Fellows at the TCC International Centre for Innovation, Manufacturing, Entrepreneurship and Technology Transfer (TCC-CIMET) have developed a low-cost, mobile clay water filter designed to restore access to safer water at both the household and community levels.

This innovation is more than a filter—it is a community-centered solution built on practical engineering and local resources. Key features include:

• Locally sourced materials: Ensuring affordability and accessibility for communities.

• Frugal engineering: Simple, effective design that maximizes performance while minimizing cost.

• Deployable and practical: Easy to implement at the household or community scale.

• Needs-driven design: Developed with real community challenges and user experience in mind.

Beyond providing clean water, this solution demonstrates how research, innovation, and local capacity can come together to address urgent environmental and public health challenges. It exemplifies human-centered innovation—technology that not only solves a problem but also empowers communities and improves quality of life.

At TCC-CIMET, we believe that clean water is a basic human right, and with practical innovation, it is achievable. This clay filter is a tangible step toward healthier, safer, and more resilient communities across Ghana.
