370 Unlocking Legionella Solutions: Perspectives on Regulations and Best Practices

"Be curious, maintain an open mind, and maintain your high standards." - Lee Bainbrigge

Our water treatment community is a close-knit brotherhood and sisterhood, regardless of where we live. We face similar challenges and share a common goal: to grow and learn from each other. Our latest podcast episode features a conversation that delves into the differences and similarities in Legionella control practices and regulations between the United States and the United Kingdom. This insightful episode features Lee Bainbrigge, Chief Sales and Marketing Officer of SMS Environmental Ltd as our charming lab partner.

Key Insights from Lee Bainbrigge on Legionella Control:

Differences in Legionella Management and Documentation In both countries, the primary Legionella control methods are keeping water moving and using temperature control. However, the UK places a stronger emphasis on documentation and compliance systems to record control measures. "The types of control you are using, you need to record it, you need to write it down in a compliance system," Lee explained. If a system tests positive for Legionella, it is crucial to effectively and clearly communicate to the client, "There's Legionella in the system. Let's look at doing something about it." In the UK, these communications are meticulously documented and kept as digital records for future reference.

Crafting Effective Legionella Legislation When discussing what lawmakers should consider when writing Legionella legislation, Lee advised caution and balance. He noted that the guidance in the USA is relatively proportionate and effective when in the right hands. "Effectively, the guidance you've got in the USA is relatively proportionate... In the right hands, you're going to do a good job with the guidance that you've got," he noted. In contrast, the UK's approach can sometimes be overly prescriptive. Lee suggests a middle ground, advocating for guidance that is neither too relaxed nor too stringent, ensuring efforts and resources truly reduce risk. "I think the most reasonable guidance you could come up with is somewhere in between the two. There are pros and cons on both sides," Lee mentioned.

ASHRAE 188 and Its Direction in the USA Lee affirmed that the USA is on the right track with ASHRAE 188 for Legionella control. "Yes, absolutely!" he responded when asked if the US is heading in the right direction. He highlighted the importance of competent professionals conducting Legionella risk assessments to ensure effective control measures. "Make sure that the people that are carrying out your Legionella risk assessment are competent and you're actually getting good advice at the beginning of your control scheme," he advised.

Challenges and Technology Opportunities in the UK In the UK, current challenges include maintaining competency and training within the industry, adapting to novel systems like heat pumps, and dealing with reduced water flow in buildings. Lee mentioned the potential of new technologies, such as the Internet of Things (IoT) and remote monitoring, which could revolutionize Legionella control, although current guidance has yet to fully incorporate these advancements. "We have got challenges with... new novel systems coming into our domestic hot and cold water systems. The use of heat pumps and different ways of sourcing energy and reducing water flow are all having an impact on Legionella control," Lee explained.

Building a Global Culture of Learning Lee is a strong advocate for collaboration within the industry. He believes in learning from each other and sharing best practices, which can greatly benefit organizations and improve public health protection. "I’m a big believer of us being collaborative in this industry," Lee shared. "When we see what somebody else is doing and establish what’s working for organizations, that is just so great to see."

Professional Standards and Certifications Lee discussed the significance of the Certified Water Technologist (CWT) certification. SMS Environmental Ltd. values high standards and depth of knowledge within its team, which is why they are strong proponents of the CWT certification. "We don't have in the UK an equivalent qualification specific to water treatment," Lee explained. "We've certainly looked at the CWT and gone, 'this does really what people that have been involved in the organization in the industry far longer than me tell me was very much the way the sector was born.'"
