WATER PROJECT

Harvesting Water from Air

Iran is one of the most water-stressed countries in the world. In the arid south of Iran there is a lack of drinking water and water for agriculture. Currently, the locals depend on water transport by truck or ship, or rely on power-expensive sea water purification techniques. But despite the lack of rain, atmospheric humidity is high in the region bordering the Persian Gulf and the Sea of Oman, creating a potential for water harvesting from air.

A simple, environment-friendly solution exists: The Dew Catcher. This ingenious device simply consists of nets that trap dew the same way spiderwebs do. The captured water then flows into reservoirs for later use. The dew catcher has already been successfully tested in several arid countries around the world, including Peru, Chili, Yemen, Oman and several African countries. Scientific studies indicate that the coastal regions at the Persian Gulf are humid enough to draw up to 100 litres of water per square meter of mesh each day.

Dew catcher

The Dasht foundation aims to build and test dew catchers on the arid island of Hormuz in the Persian Gulf. Construction is simple: we set up two masts, with a durable mesh in between, and collectors below. The moisture trapped in the mesh makes its way to storage containers through gravity. The water can be made suitable for drinking through filtering, or it can be used to grow fruits and vegetables. This can yield a stable source of income for local communities.

We seek support for a feasibility study through crowd funding. Our aim is to install 2 dew catchers of 4 square meters each on Hormuz after which we will monitor their water production. We will involve locals and instruct them on how to use and maintain the dew catchers. In a few years time, fog harvesting at larger scales may help revitalise the area, providing the local communities in the arid south of Iran with the water supply that they so desperately need.

With no other sources of funding, we kindly ask you for financial support. Dasht is a non-profit foundation that guarantees full transparency in how donations are used. Click here to help us get this project off the ground!
