My name is Ahmad Odeh, I am a 10th grader in the Jordanian international schools. I am looking forward to participating in the Stockholm Junior Water Prize.
Tell us what the water concern in your country is!A concerning amount of 2.25 m3 of water is wasted yearly waiting for hot water to come down from solar heaters. Even provided water in jordan is mostly wasted due to the lack of preservation.
This is what I think is one of the solutions for a sustainable future:ECOFLO PRESENTS: a hot water recirculation pump that recirculates cold water from the pipes of the solar heaters to the upper tank until reaching desired temperature…. It features a heat detector that will shut it off when the temperature is reached.

EcoFlo: Saving Every Drop One Circuit at a Time
The global water crisis is one of the most pressing environmental challenges of the 21st century, with approximately 2.1 billion people lacking access to clean water. Water waste, particularly in domestic hot water usage, exacerbates the problem by reducing water availability, especially in regions already facing water scarcity. This research presents Ecoflo, a sustainable, energy- free solution designed to optimize water usage in households with solar water heating systems. The Ecoflo system consists of a recirculation pump that allows cold water to be cycled back into the system until it reaches the desired temperature, thus reducing water waste. This study focuses on assessing the system’s efficiency in saving water, its ease of installation, and its environmental impact. A pilot study…
