How Hard Water Scale Affects Legionella Growth

How does hard water scale affect Legionella growth? And does hard water scale contribute to biofilm? The presence of hard water scaling is a dangerous issue due to its strong contribution to biofilm and Legionella growth.  Industrial water softeners are the solution and should be a part of any Legionella control system or Water Management Plan. Softeners won’t remove scale but will prevent more from forming.  Several free Legionella control industrial water softener sizing guides and calculators can be found here.

These softener systems eliminate scale caused when calcium builds up from the water.  When hard water is heated, it has a much higher tendency to scale up the plumbing and equipment, especially in hot water heaters, boilers or hot water plumbing. This not only shortens the life of all plumbing systems and fixtures, but it also provides a medium for the growth of bacteria, Legionella, biofilm that protects Legionella, and other harmful germs and microorganisms within the water system. Further protection from legionella and harmful germs can added with the addition of a Legionella Control System.

With a minimal amount of planning and investment, the negative aspects of hard water and harmful Legionella growth can be avoided. A water system clear of scale prolongs the life of all water related equipment and fixtures and helps prevent Legionella and biofilm from proliferating.

Other significant savings are achieved by operating a company with softened water, which include: Water Conservation, Decreased Energy Costs, Maintenance Savings, and Reduced Liability.
