Legionella is a type of bacteria commonly found in water. It occurs in low numbers in natural water sources such as rivers and lakes. However, they can also be found in purpose-built water systems such as evaporative condensers, hot and cold water systems, cooling towers and spa facilities.

Legionella risks

The inhaling of infected water droplets results in Legionnaires’ disease – a serious condition that causes breathing difficulties and chest pain.

It is essential that owners of new buildings are aware of Legionella when pre-commissioning new water systems and that they adhere to the legal requirements of the Health & Safety at Work Act 1974 1.

Legionella sampling and disinfection

Legionella sampling is essential to ensure healthy water systems, and the implementation of an accurate, pre-planned maintenance (PPM’s) system is vital. This may involve precise temperature monitoring of the water.

At Higgins we are fully equipped to advise and carry out the Legionella assessment, the disinfection of water systems and the continual sample monitoring for your business.
