In Malawi, climate change is intensifying natural disasters like cyclones and droughts, severely impacting water availability. Our response, "The Better Kitchen Sink," aims to alleviate water scarcity and improve community resilience. This low-cost, low-tech greywater filtration system is gravity-powered, requiring no electricity, making it ideal for remote and resource-limited areas. It transforms greywater, constituting 70% of household water use, into reusable water, preserving vital drinking water reserves. Our system, designed with locally sourced materials, is practical for even the smallest homes. It not only filters water for reuse but also reduces environmental contamination and supports gardening and irrigation with nutrient-rich greywater. This empowers individuals to contribute actively to water management, fostering a community of informed citizens. Our project has reached significant milestones, including prototype development and production. We have initiated field testing in Malawi, where we brought 12 prototype sinks to refugee camps and rural villages, obtaining valuable in-person feedback and online feedback with our newly established feedback network system. We also expanded testing to India in December 2023 for feedback in another setting. Our dedicated team remains committed to using user feedback to enhance the product, advancing our mission to provide sustainable water solutions to impoverished communities.
