Financial building banks on UV protection against Legionella in plumbing

Major outbreaks of Legionnaires’ disease struck the Netherlands in 1999 and 2006, affecting the health of over 200 people. As a result, the Dutch government now requires all public buildings to conduct a risk analysis for Legionella and to implement a prevention and control plan. A financial building in Amsterdam found that the Legionella bacteria posed a threat to the building occupants—so the building managers acted quickly to find a solution that would ensure reliable protection.

Best Air Choice, a local clean air and water specialist, recommended and installed a UV Pure Upstream system in the basement where the water supply enters the building. All of the building’s plumbing was disinfected with ozonated water to minimize any risk of bacterial regrowth in the UV-treated water supplied by the UV system. Since commissioning of the system, the building consistently reports non-detectable levels of Legionella bacteria.

Best Air Choice identified UV Pure disinfection systems as the best technology to reduce the risk of Legionella and other waterborne pathogens in public potable water systems. The systems’ advanced Crossfire Technology provides a greater disinfection dose over a short path length than conventional “light-in-a-pipe” UV systems and consistently provides 4-log (99.99%) removal of Legionella as well as other potentially harmful bacteria, cysts and viruses.

“UV Pure’s Crossfire Technology is unique in the Dutch market. There are no other products that match the performance and reliability these systems offer.”

The company has been installing and servicing UV Pure systems in public buildings throughout the country and says their customers are extremely pleased that the systems consistently achieve the targeted reduction of Legionella bacteria while being simple to operate and maintain.
