Harvest rainwater with Water Bench

Water BenchThe Water Bench is outdoor furniture that collects and stores rainwater to irrigate outdoor spaces independent of public water supply. Inspired by the Chesterfield couch design, MARS Architects created the park bench in connection with the BMW Guggenheim Lab project as part of a series of sustainable urban strategies. MARS Architects was founded by Dutch architect Neville Mars and has offices in Shanghai, Mumbai and Hong Kong. They specialise in complex, site-specfic construction projects with a strong drive for sustainability and functionality.

Putting your park furniture to work

There are many parks all around the world using millions of liters of water to maintain a lush, green vegetation during the dry summers. On the other hand, the overflow of water received during the wet season is not being captured to cater for these dry spells. In order to balance this out, MARS Architects created the Water Bench which harvests and stores rainwater in an integrated water reservoir. The water is “absorbed” through the Chesterfield look-a-like buttons into a 500 liter tank. Alternatively, the Water Bench can be installed with an additional 500 liter underground tank. An even bigger model can store 1800 liters. All models are made from partially recycled polyethylene. The 1000 liter bench is priced USD 1000.

Other rainwater harvesting solutions

MARS Architects understands that even though the water supply infrastructure is increasing, the reservoirs are ever further removed from the cities, unable to keep up with demand. Therefore, their designs consider local solutions for a global problem. Rainwater harvesting is an obvious choice as regulations are already in place and no large infrastructure is needed for transportation. Next to the Water Bench, Mars Architects designed three more solutions to futher supplement the water system:

  • Water wall: store water separately in modular walls cells that are connected to the roof, serving as clear walls to allow daylight penetration and UV filtering
  • Weather tap: a combined rainwater catchment and solar desalination structure that can contribute to distributed water storage and supply
