Portable filtration device design models tech for good to combat unsafe drinking water

Kenna and Margot are students in the US. They were inspired to create a solution to the problems faced by people around the world where the impacts of poor access to clean water and sanitation can cause illness or death.

I am really glad that our work paid off, and I hope that our prototype will inspire people to start paying more attention to water access for everyone.

Kenna, winner, 8 to 14-year-olds in North America.

When learning about this issue they discovered that three out of ten people in the world lack access to safely-managed drinking water. The purpose of their design is to prevent viral and bacterial infections from being spread including, Hepatitis A, E coli and Cholera.

The design is made to be affordable and portable so that it can be used by as many people as possible. They have achieved this by creating a prototype that uses renewable energy with solar power and simple UV LED hardware components to sterilise the drinking water.

Kenna and Margot’s device is the winning entry in the do your :bit category for 8 to 14-year-olds in North America. It is dedicated to contributing to Global Goal 6, Clean water and sanitation.

You can watch the video to find out more about how their prototype is designed.

The do your :bit challenge is an annual competition which sets young people the challenge to innovate and design solutions relevant to the impacts of the Global Goals that are meaningful to them.

Children and young people innovating with technology

The do your :bit challenge adds social purpose to digital learning and allows students to apply their digital skills to real world solutions. All projects and lesson resources are available for free and entries can be submitted into two age-range categories, 8 to 14-year-olds and 15 to 18-year-olds. 8 to 14-year-olds can submit either a paper prototype or working micro:bit solution.

Read about all of this year’s winning entries.

The next do your :bit challenge opens in early 2022, you can find out more about the challenge and access Global Goals project resources and lessons here.
