Sanitation Technology Hackathon 4: Greywater Recycling for Small-Scale Agriculture

The “Greywater Recycling for Sustainable Agriculture and Kitchen Gardening” hackathon aims to promote technological innovation and solutions for treating and recycling greywater from households to support sustainable agriculture and kitchen gardening. Greywater, which typically includes wastewater from sinks, showers, laundry, and baths, can be a valuable resource when properly treated and repurposed for irrigation, reducing water wastage and the need for freshwater in agriculture.

Hackathon 4 Objectives

• To encourage participants to come up with innovative and practical solutions that address water scarcity, sustainable agriculture, and environmental conservation.
• To facilitate collaboration between participants with diverse expertise, including engineers, environmentalists, data scientists, and community engagement specialists
• Promote the development of open-source technologies and solutions that can be accessible and adaptable for different regions and communities.
• To showcase the importance of circular economy principles, where resources are efficiently reused, and environmental impact is minimised.

Key Areas of Focus

Participants in this hackathon can choose from the following key areas of focus:

• Greywater Treatment Technologies: Innovators can develop cost-effective and efficient greywater treatment systems that can safely clean and disinfect greywater for agricultural use. They could also explore innovative methods for purifying greywater, such as filtration, biological treatment, and disinfection techniques. Innovators could as well, under this focus area, consider sustainability, energy efficiency, and ease of maintenance in treatment system designs.
• Smart Irrigation Systems: Under this focus area, innovators can create advanced irrigation systems that can be controlled and optimized to distribute treated greywater to kitchen gardens and small farms. They will explore possibilities of incorporating automation and data-driven solutions to optimize water distribution, enhancing plant growth and minimizing water usage as well as design user-friendly interfaces for controlling irrigation systems.
• Sensor and Monitoring Solutions: Innovators will be invited to design and develop sensors and monitoring tools that help users track the quality of treated greywater while ensuring that the treated greywater meets the necessary standards for safe agricultural use. The innovation should explore real-time monitoring and reporting solutions to ensure ongoing water quality.
• Community Engagement and Education: Under this focus area, innovators will be invited to develop outreach programs, educational materials, and awareness campaigns to promote the adoption of greywater recycling for agriculture within communities. This focus area further emphasizes the benefits of sustainable water use, environmental conservation, and resource efficiency. The innovation should provide for community involvement and cooperation in implementing greywater recycling practices.
