Amazing savings: 14-year-old develops a simple invention that can reduce water waste by up to 7.300 liters per year just by taking a shower. Find out how it works!
Wasting water while showering is a critical issue that affects both the environment and people. finances household. We often don't realize how much water is wasted when we leave the shower on for long periods of time, whether while we soap ourselves up or just wait for the ideal temperature.
This habit, common in many homes, can have a major impact on water consumption, especially in places facing a shortage of this vital resource.
In addition to the environmental impact, wasting water while showering also has a direct impact on water and energy bills. With rising rates and growing concerns about sustainability, it is essential to adopt more conscious practices in our daily lives.

Small changes, like reducing your shower time or using flow control devices, can make a big difference, both for your wallet and for the planet.
Knowing this, an innovation emerged that draws attention for its simplicity and efficiency, created by a young girl of just 14 years old. Rani East-Jeffs, a 7th grade student on the north coast of New South Wales, Australia, developed the Aqua Loop, a device that could revolutionize the way we use water in the shower.
The invention earned him the prize NSW EduTech Young Inventor of the Year, an important recognition for young talent in the field of technology and education.
The invisible waste of water in the shower
To understand the magnitude of Rani's invention, it is important to look at a problem that often goes unnoticed in everyday life. When we turn on the shower, we often wait a few minutes for the water to reach the ideal temperature.
During this time, the cold water that comes out of the pipes is simply wasted. According to research carried out by the young woman, one minute of showering consumes, on average, 20 liters of water. If the wait for hot water is two minutes, for example, up to 40 liters are thrown down the drain without any use.
Rani noticed this waste and saw an opportunity. Instead of focusing on devices that reduce water flow, as is common in the market, she proposed a completely different solution: prevent water from coming out of the shower until it reaches the desired temperature.
The creation of Aqua Loop to save water
With this idea in mind, Rani developed the Aqua Loop, a simple and efficient device that is installed in the hot water pipe and detects the water temperature.
The device blocks the water from flowing out until it is hot enough for bathing. In other words, it prevents the waste of liters of cold water while we wait for it to heat up.
It all started with a school project. Rani’s school organized an activity focused on saving water, and the young girl decided to study the shower in her own home. Although her family already had an efficient water heating system, Rani calculated that she was still wasting 5 liters of water with each shower.
In a household of four people, this meant an annual waste of around 2.628 liters just waiting for the water to heat up.
"With Aqua Loop, the cold water doesn’t even come out of the shower. It is recirculated back into the hot water system until it reaches the ideal temperature”, Rani explained in an interview.
An unexpected recognition
What started as a simple school project ended up taking on much larger proportions. Rani, determined to pursue the idea, entered her project into the Young Inventors Conferences, organised by the Powerhouse Museum in Sydney.
During the event, his device caught the attention of Eman Soliman, founder and CEO of EduTech Australia, a company focused on technology education.
"We wanted to encourage girls to participate in the program, especially in robotics, and help them develop entrepreneurial skills, learn how to structure their businesses and create value propositions.”, Soliman explained.
The promising future of a young inventor
Thanks to the program's support, Rani East-Jeffs not only won first prize in the contest with the Aqua Loop, but also secured a grant to continue developing his invention.
Now, the young woman has the chance to bring her device to market and, who knows, make a significant contribution to saving water around the world.
Rani East-Jeffs’ story is an example of how small ideas can have a huge impact. Her invention not only offers a practical solution to an everyday problem, but also highlights the importance of programs that encourage creativity and innovative thinking from an early age.
By combining technology and sustainability, Rani is not only saving water, but also paving the way for a generation of young female inventors seeking solutions to global challenges.
At just 14 years old, Rani has already made a significant contribution to preserving one of the planet’s most precious resources, proving that innovation can come from anywhere — even the average household shower.
