Addressing the perils of stagnant water in healthcare

Heating, cooling, plumbing, and infrastructure specialist, Uponor’s new CIBSE-approved CPD, ‘Systems for Water Hygiene’, aimed at mechanical design engineers and plumbing installers, highlights the risk of Legionella on the plumbing network, advising on best practice installation layouts and new technology, with a focus on ‘the perils of stagnant water on the network’.

Dave Lancaster, applications specialist, explained: “Our CPD highlights the fact that Legionella will breed rapidly in any plumbing installation where stagnant water can collect at temperatures between around 25˚C and 45˚C. It also suggests pipe network designs, new product innovations, and materials that can be used to minimise the risk, for a much healthier, more hygienic, installation.”

The CPD explains that the risk of Legionella on the pipe network has increased in recent years due to new water-saving technologies used to reduce flow velocity, and how design innovation can improve water safety while supporting more efficient demand. It outlines the varying levels of risks for Tee, Serial, and Loop installations, highlighting the benefits of Serial and Loop installations in avoiding dead ends and deadlegs where stagnant water can collect if the plumbing is not in regular use or flushed regularly, and ‘the benefits of using PE-X or MLC (multi-layer composite) pipe’.
