Water Systems can potentially be a source for Legionella growth

tapsAny water systems that have the right environmental conditions could potentially be a source for Legionella bacteria growth. At low temperatures (under 20°C) the bacteria survive but do not multiply, over 60°C the bacteria die, therefore the optimum growth of the bacteria is 37°C. Where there is stagnant water in a system, the bacteria will flourish. However the Legionella bacteria can only infect your body through inhalation of contaminated water droplets. This would be through systems such as hot tubs, fountains, cooling towers and/or taps and showers.

Approved Code of Practice by the HSE (ACoP L8)

By following the Approved Code of Practice by the HSE (ACoP L8) the risk of contamination of the disease will be minimised. This Code of Practice is designed to ensure that providers establish and maintain management systems which deliver consistent provisions for the prevention or control of Legionella.

Control of Legionella in spa-pool systems

This guidance is primarily for those who manage or operate spa-pool systems and explains how to manage and control the risks from Legionella and other infectious agents. It will also help service suppliers, designers, manufacturers, importers, suppliers and installers of spa-pool systems meet their legal responsibilities.
