The Hydroleaf

A Solar-Powered Rainwater Purification System and Drinking Fountain

Mostafa Bonakdar
, a design student from Tehran, recently launched a design for a solar powered rainwater catchment system. The Hydroleaf is a unique device that collects rainwater, then uses solar energy to power a water purification system which supplies a fountain on the same device.

The public hydration station features a photovoltaic solar canopy at the top of the structure that uses solar energy to power a water purification system. Rainwater is collected at the top of the structure and funneled through the purification system. A drinking fountain on the bottom of the Hydroleaf supplies the public with the purified water. The container is able to store up to approximately 60 liters of filtered water. The solar panels also offer a small shelter, perfect for covering a park bench or acting a bus stop.

The Hydroleaf has come with some critique including possible impracticality of the device due its high energy use. The ability for the structure to withstand harsh winter weather or high wind has also been called into question. The design has also merited much praise as it is a self-contained system that utilizes clean energy for water purification. Should the design prove efficient and practical, the Hydroleaf might someday provide safe drinking water to the masses, greatly reducing dependence on plastic water bottles and giving more people access to clean drinking water. We hope to see these in cities everywhere in the future.
