World Water Day: Save 40,000 litres of water each year with a simple and innovative austrian technology

This year’s motto of the World Water Day is “The Value of Water” and it urges people to use one of the planet’s most precious natural resources sparingly on the 22nd of March. In daily life, water consumption can be reduced most effectively if the corresponding savings measures are not associated with inconvenience or restrictions. Technical innovations like the ECOTURBINO make that possible. The mini-turbine developed by the Rabmer Group saves around 40 per cent water within every shower – and thus up to 40,000 litres of water per household each year.

Altenberg, on the 17th of March, 2021. Saving water at home not only helps to protect the environment, but also reduces operating costs. It is particularly worthwhile to save water in the bathroom – after all, this is where around two thirds of all water consumption in households take place. [1]

One minute inside each shower “swallows” 12 to 15 litres of water [2], so after six minutes around 80 litres end up in the drain. Although consumption can be drastically reduced by technical support – for example by using energy-saving shower heads – this often results in a noticeable loss of comfort. The Rabmer Group from Upper Austria solved this problem with the development of the ECOTURBINO. The mini-turbine can be installed without great effort and saves around 40 percent water and energy within every shower, without the user noticing a thing.

A household with four people reduces its operating costs by an average of 250 euros per year with the respective technology, saving 40,000 litres of water and half a tonne of CO2 annually. If only one in five of the total of 3.9 million private households in Austria were equipped with an ECOTURBINO, 9.7 billion litres of drinking water, 124,700 tonnes of CO2 and ultimately 385.5 million kWh of energy could be saved each year.[3]

How the ECOTURBINO works

The device is installed directly in the shower, as a connecting piece between the fitting and the shower hose. Normally, no tools are required for installation and no more than two minutes are needed. The mini turbine unfolds its full effect the very next time you take a shower.

A strong cross-sectional constriction inside the ECOTURBINO allows only a reduced amount of water to pass into the shower hose. The resulting negative pressure draws in air, which creates a swirling water-air mixture in the device. This hits the shower head at high speed and ensures a high water jet intensity despite lower water consumption.

Der ECOTURBINO spart somit Wasser bei gleichbleibendem Duschkomfort. Als zusätzlichen Bonus bietet er zudem einen hygienischen Mehrwert: Durch die starke Verwirbelung des Wassers unter Beimischung von Luft bleiben der Duschschlauch und der Duschkopf frei von Ablagerungen und Biofilm. Das wiederum mindert die Gefahr von Keimbildung und Legionellen.

Therefor the ECOTURBINO saves water while maintaining shower comfort. As an additional bonus, it also offers added hygienic value: the strong turbulence of the water with the addition of air keeps the shower hose and the shower head free of deposits and biofilm. This in turn reduces the risk of germ formation and legionella.
