How The Risk Of Legionella Is Increased

How The Risk Of Legionella Is Increased

- Stagnant Water:

Legionella thrives in stagnant or slow-moving water. Risks increase in plumbing systems, cooling towers, or fountains that are not regularly used or maintained.

- Warm Water Temperatures:

Optimal growth occurs between 20-50°C. Systems like hot tubs, hot water tanks, and heated swimming pools often operate in this temperature range.

- Poor System Maintenance:

Biofilm, scale and sediment in water systems protect bacteria and encourage their growth. Infrequent cleaning and disinfection of these systems elevate risk.

- Aerosol Generation:

Legionella spreads when contaminated water is aerosolised and inhaled. Showers, misters, air conditioning, and whirlpool spas can create aerosols.

- Ageing Infrastructure:

Older plumbing systems can harbour more sediment and corrosion, both of which can promote Legionella growth.

- Immunocompromised Populations:

Facilities like hospitals and care homes are at higher risk due to the vulnerability of occupants.
