XWater is a smart urban pavement water management system that comprises hexagonal concrete pavement units and a water storage system. The pavement units contain micro detention cylinders that slow down and store rainwater, which can then infiltrate into the ground. This feature allows cities to replenish groundwater and mitigate the rate of urban sinking.

This integrated system seeks to tackle waste contamination in Singapore through the implementation of smart dustbins equipped with a lightweight and highly accurate model that can differentiate recyclables from non-recyclables. The prototype utilises Raspberry Pi and computer vision technology, achieving a high accuracy of 82.1% in sorting recyclable and non-recyclable trash.

Super Solar System uses water cooling to boost solar panel efficiency and generate extra electricity. It diverts water from rooftop tanks to pipes placed beneath the solar panels, creating a continuous flow of water that effectively cools the system. This approach not only enhances panel efficiency by reducing its temperature but also generates additional electricity through a thermoelectric generator that utilises the waste heat from the panels.

Check out the range of innovative solutions from our finalists, who were also showcased at Ecosperity Week 2023 in Singapore.

Sustain-a-City: An Urban Innovation Challenge

Did you know…

Cities cover only 2 per cent of the world’s surface and are home to slightly over half of the world’s population. Yet they consume a disproportionate 78 per cent of the world’s energy, and produce over 70 per cent of global greenhouse gas emissions.

What would a sustainable, net-zero city look like?

Sustain-a-City: An Urban Innovation Challenge is open to all registered students between 18-25 years old (as of registration date). Grab your friends, form a team of up to 3 and register before 5 April 2023!

Participants will attend 3 virtual design workshops this April 2023 conducted by Arkki’s Design and Creative Coaches. That’s not all. Our coaches will also engage your team with 1-on-1 coaching sessions to guide all of you towards a successful submission.
