Perhaps you supply water to high-risk groups such as children, older people, or immunocompromised individuals.
Always bear in mind that a compromised plumbing system can detrimentally affect the quality and safety of the water it delivers, risking illness or even a fatality among at-risk groups. Many outbreaks of waterborne disease can originate from a distribution or plumbing system, for instance Legionnaires disease or salmonellosis.
Drinking water deteriorates between the treatment plant and point of use.
A recent study by Li et al (2022) of one system in the Netherlands traced how changes occur to the microbiology and quality of water as it travels from treatment plant to use.
The study investigated the risks that plumbing systems can pose to water quality and safety and pointed to solutions. Learn more about the findings of this study here.
