Problem statement:
Polluted water bodies, such as rivers and streams, suffer from high levels of organic waste, heavy metals, and low oxygen, harming ecosystems and biodiversity. Our idea of floating islands aims to naturally purify water using specific plants and filtration systems.
 
Who is affected by the problem? Who is the target group for your solution?
Communities living near polluted rivers, especially in urban or agricultural areas, are affected. The target group includes environmental agencies, local municipalities, schools, and youth eco-leadership programs seeking sustainable water purification solutions.
 
Why is this problem urgent / important? What is the cost of not solving this problem?
Leaving polluted rivers untreated results in long-term damage to ecosystems, public health risks, and loss of biodiversity. The cost includes reduced quality of life, water scarcity, and economic loss for communities depending on these water sources.

Briefly explain how your solution addresses the problem:
Our floating islands combine aquatic plants, gravel, and UV filtration to absorb pollutants, trap sediments, and oxygenate the water. This low-cost, nature-based system improves water quality without chemicals or heavy infrastructure, making it accessible and eco-friendly.
 
What is new or different? What sets your approach apart from others?
Unlike traditional water treatment plants, our solution is decentralized, sustainable, and educational. It integrates environmental science with youth involvement, offering a hands-on tool for learning and action. The use of floating wetlands with native plants and solar-powered UV lights is both innovative and scalable.
 
Potential impact: What change or benefit would result if your idea succeeds?
Cleaner rivers, restored habitats, and increased biodiversity would result. Communities would gain a sustainable tool for water stewardship, while youth participants develop environmental leadership skills. If scaled, this solution could support climate resilience and reduce pollution in urban and rural waterways worldwide.
 

What existing alternatives or competitors do you see out there?
Traditional solutions include centralized wastewater treatment plants, chemical treatments, and mechanical filtration systems. Some floating wetland projects exist, but they are often expensive, lack community engagement, or focus solely on aesthetics rather than measurable water purification.
 
What gives you confidence your solution could work?
Our pilot experiments demonstrated clear reductions in pollutants, improved dissolved oxygen levels, and visible water clarity. Scientific studies support the effectiveness of phytoremediation and constructed wetlands. The combination of local materials, ecological design, and youth involvement makes the solution both practical and replicable in diverse settings.
 
What is the biggest anticipated challenge for the implementation of your solution?
Securing long-term funding and community buy-in may be challenging. Maintenance and monitoring require local ownership, which depends on education and sustained engagement. To overcome this, we plan to partner with schools, municipalities, and environmental organizations to ensure continuity and shared responsibility.
