‘capture the rain’ skyscraper by ryszard rychlicki and agnieszka nowak

polish architectural students ryszard rychlicki and agnieszka nowak of H3AR received a special mention for their proposal in the 2010 skyscraper competition.

‘capture the rain’ skyscraper is a building whose roof and external shell, which consists systems of gutters, are aimed at capturing as much rainfall as possible to meet the daily needs of its inhabitants. average daily consumption of water per person is 150 liters, out of which 85 liters may be replaced by rain water. within the last thirty years water consumption has significantly increased. there are lots of factors that contribute to such an increase such as increasing number washing machines and dish washers, increasing popularity of garden showering devices and flushing toilets. a third of water being used in households in western countries is flushed in toilets. since 1900 the total water consumption in the US has increased by 1000%. at present, an average american uses five times more water that a citizen of developing countries. such an increase is related to among others improved living standards. on the other hand, a national hobby of the danes is collecting rain water for washing and watering plants. within the last ten years average use of pure water in denmark dropped by 40% and inhabitants of the so called eco-villages use a third part of the national average.

in view of this data, they decided to design a tower, whose structure will allow for capturing and processing as much rainfall as possible to provide with water for its inhabitants. millennia plants have been developing systems of capturing and processing rainfall. such systems helped them to deal with water deficits or surpluses. similarly, they wanted to copy their simple mechanisms of rainfall capturing and processing. initially, in designing the tower, we focused at shaping and modeling the surface of the roof to capture as much rainfall as possible. under a roof’s surface, there are water reservoirs in the form of a large funnel and reed fields, which serve as a hydro botanic water treatment unit. the unit processes water into usable water that is further transmitted to apartments. a network of gutters on the external surfaces of the building is designed to capture rainfall flowing down the building. such flowing rainfall is transmitted to floors and its surplus is stored in a reservoir under the building. water captured and processed by the building may be used for flushing toilets, feeding washing machines, watering plants, cleaning floors and other domestic applications. having analyzed rainfall in several large cities in developed countries, we obtained a formula that shows what percentage of daily pure water consumption may be replaced with rainfall thanks to the technology applied in their building.

  • Great concept! Congratulations! Hopefully, someday soon we get to incorporate this kind of efficiency in structures around us.

  • rodrigo: believe it…I live in Mozambique and I only have a 500L water tank in my house, which defines my daily use. It is normally just enuogh for 4 people…it’s sad but it’s good to have a direct feedback on how much water we use.

  • average daily consumption of water per person is 150 liters?? ummm…..i don’t think so

  • Sorry to say Hammer, but maybe you don’t know that much on how the US sewer systems work? The millions and millions of gallons of untreated water that is dumped from waste water facilities during a large rain event because it puts the facility over capacity. Aside from collecting usable water, rain water collection would help with storm water run-off and help reduce the amount of pollution into local waterways. The number one pollutant in local streams, rivers, lakes & delta’s is storm water run-off. Find out where your local sewer systems dump their water & you might change your mind…..
