SanTech Hackathon 2023-24

Deadline: 28th of February, 2024

Ideators and problem solvers, unite!Come participate in FINISH Mondial’s fourth annual hackathon, where they will address the critical issue of recycling greywater for kitchen gardening and sustainable agriculture.

In order to promote sustainable agricultural methods, this hackathon seeks to foster technical innovation and provide solutions for cleaning and recycling graywater from homes. Greywater, or the wastewater from baths, showers, laundry, and sinks, may be converted into an invaluable irrigation resource that lowers water use and the need for freshwater in farming.

The hackathon will focus on four key areas:

  • Greywater Treatment Technologies:

Participants in this focus area 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 also, under this focus area, consider sustainability, energy efficiency, and ease of maintenance in treatment system designs.

  • Smart Irrigation Systems:

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, enhance plant growth, and minimize water usage. They should design user-friendly interfaces for controlling irrigation systems.

  • Sensor and Monitoring Solutions:

Participants can 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 innovations should explore real-time monitoring and reporting solutions to ensure ongoing water quality.

  • Community Engagement and Education:

Innovators can 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 innovations should provide for community involvement and cooperation in implementing greywater recycling practices.
