A British company co-owned by water treatment specialist and the technology’s inventor Ian Helmore and BBC Dragons Den “dragons” Deborah Meaden and Theo Paphitis has developed a shower system that uses low voltage technology to reportedly eliminate the risk of Legionella bacteria release on shower activation.
Steri-Spray’s patented UV technology is designed to minimise Legionella outbreak risk by keeping its shower heads free from bacteria growth at all times, and treating incoming water supply to destroy any bacteria in the feedwater passing through the unit. The company elaborates: “Water flows in via a flow-regulated inlet pipe and safety latching water valve, and thence into the UV reaction chamber, inside which it passes around the outside of a quartz tube encapsulating an ultraviolet lamp. UV light passes through the quartz tube and penetrates the water, destroying any bacteria by breaking down its cell wall. The lamp’s continuous operation eliminates bacteria even during low use, obviating the need for routine purging or flushing. In addition to Legionella, the technology also reportedly eliminates other harmful bacteria such as Steno. Failsafe and monitoring devices within Steri-Spray showers constantly analyse the system to ensure that correct operation. In the event of failure, safety devices automatically activate to ensure no untreated water can exit. A singleuse flexible showering attachment directly connectable to any model is available for those requiring the flexibility of a shower hose.
