According to data, just 200 shower heads will cause about 10 million liters of tap water to flow into the sewer pipes every year. In order to save water consumption in shower heads, Australias Commonwealth Scientific and Industrial Research Organization (CSIRO) has developed a shower head that can save 50% of shower water consumption. This nozzle uses the negative pressure of the water flow to "suck" air in to form a hollow bubble, which not only ensures a comfortable bathing experience but also saves a lot of water. This nozzle can be installed on common bathing facilities currently on the market and is already on sale in Australia.
