Every drop counts with new rain harvesting panels at the V&A Waterfront

The V&A Waterfront will be among the first companies in South Africa to test a highly innovative new design in rainwater harvesting technology.

The Aquatecture rain harvesting panel collects water by diverting raindrops flowing over the perforations on the surface to the inside of the system.  From there the water trickles down into a collection tank where it can either be stored for later use, or can be pumped back into a building’s grey water system.

The panel is also currently being developed to harvest moisture from the atmosphere.

Aquatecture is the brainchild of South African born designer Shaakira Jassat. Although she lives in the Netherlands now, Jassat witnessed Cape Town’s devastating drought when she attended the Cape Town Design Indaba as a speaker in 2018. She was determined to design a rain harvester that was compact and aesthetically suited to the urban environment, which is now the Aquatecture panel.

Manufactured from aluminium, the panels are resistant to corrosion and can be installed on the exterior of buildings or they can be used as freestanding units in areas with more open space. They will be tested at the Granger Bay parking garage over the next two years, and all water collected will be used at the Oranjezicht City Farm Market. This test facility is made possible in collaboration with Arup, Geustyn & Horak, JoJo Tanks, Baloo Plumbing and Longspan Gutters.

New Aquatecture rainwater harvesting technology to be tested at the V&A Waterfront.

Rainfall data specific to the area will be collected during the testing period and measured against weather variables, for example, the direction of rain, wind, and the amount of rain that fell during each period. The panels will also be tested for efficiency and impact on the surrounding environment.

V&A Waterfront CEO David Green said, “The V&A Waterfront has been at the forefront of water saving in Cape Town since 2009, when we first introduced water conservation measures. We recognised even then that water was a highly pressured resource. By 2016 when the drought was first making its effect felt, the Waterfront had saved 25% on overall water consumption based on year-on-year figures from 2010.

“Saving water is now an integral part of every development and of our overall sustainability programme.  In addition to rainwater harvesting, the Aquatecture panels are also compact and visually appealing so they will integrate well into most urban architectures.”
