If you haven’t noticed, we are having a bit of a water crisis in the Western Cape. With dwindling dam levels and only a faint promise of rain on the horizon, it has become clear that we need to a fresh approach if we want to solve this dilemma.

H2O Catchers has an idea: Turning fog into water.

According to H2O Catchers, this method of capturing water has already been explored around the world. Previous research has shown that fog catchers can capture anywhere between 100 to 10 000 liters per day, depending on the density and amount of fog.

They would like to refine the process, making it more sophisticated and sustainable for the environment and humans.

What’s the plan?

“Our goal is to capture water from fog in certain areas of the Western Cape in order to provide rural areas, towns and cities with fresh water,” explains Grant Vanderwagen, Managing Director and Vanderwagen House.

A couple of years ago while watching CNN I noticed this simple yet effective way to capture water from fog. […] I had never thought about doing more research because I thought there wouldn’t be a need. Quick reality check, isn’t the Western Cape in it’s worst drought in over a century?”

H2O Catchers are looking for partners and funders to help them achieve their goals. “We are in the process of seeking funding in order for us to create our first Fog Farm here in the Western Cape,” says Vanderwagen. 

Funding and support will allow them to set up their first 100 H20 Catchers in areas that experience heavy fog. “Our plan is to keep testing new methods of sourcing water by using different mesh nets and structures that could be used to collect fresh water.”

How does it work?

They are already working on a design prototype that can be created out of recycled materials. You will have a 3m X 3m shell that is light-weight, eco-friendly, easy to maintain and of course effective. They are also exploring ways to 3D print the shells.

They will then use mesh to capture water from the fog. While there are a number of materials that can be used for this, they will be testing 4 top materials. “New developments of 3D net structures and spiderweb-type materials are producing good results but are still in early stages” Vanderwagen explains.

They need your help

“In order for us to tackle the water crisis in the Western Cape we would need to get our project up and running within a few months. We are looking for businesses that can add value to our efforts in terms of plumbing supplies, building materials, recycling production, 3D printing and knowledge into weather and fog patterns,” says Vanderwagen.
