The UK Health Security Agency (UKHSA) is investigating a number of cases of Legionnaires’ disease in Rotherham, working with Rotherham Council and other partners to establish whether they may be linked to a common source. While the risk to the wider public has been described as low, the investigation is a timely reminder of the importance of effective water hygiene and Legionella control.
Legionnaires’ disease is a potentially serious form of pneumonia caused by inhaling tiny water droplets containing Legionella bacteria. These can be produced by building water systems, including showers, taps and other equipment. The bacteria can multiply under favourable conditions, particularly where water is warm, stagnant or poorly managed.
How Does Legionella Develop in Building Water Systems?
Legionella bacteria can grow in a range of man-made water systems if conditions allow. Factors such as infrequent water use, unsuitable water temperatures, scale and biofilm can increase the risk.
This makes regular monitoring and maintenance essential, particularly in buildings with complex water systems or vulnerable occupants. Healthcare facilities, hotels, offices, leisure centres and other commercial premises all need appropriate controls to manage potential risks.
Why Are Legionella Risk Assessments Important?
A suitable Legionella risk assessment helps identify potential hazards within a building’s water systems and establishes what measures are needed to control them.
Goodwater provides water hygiene services, including Legionella risk assessments, monitoring programmes, water sampling, remedial works and disinfection. Its approach helps building owners and facilities managers understand their responsibilities and implement appropriate control measures.
Risk assessments should be reviewed when systems or building use change, and control measures must be maintained rather than treated as a one-off exercise. Regular monitoring and clear records also help demonstrate that water hygiene arrangements are being managed effectively.
Managing Water Hygiene Risks
Different buildings and water systems require different approaches. Depending on the assessment, measures may include temperature monitoring, cleaning and disinfection, flushing infrequently used outlets, maintenance work or specialist water treatment equipment.
Goodwater also provides water treatment solutions designed to help manage bacterial risks in building water systems. The appropriate approach depends on the individual system, its use and the risks identified.

Taking a Proactive Approach
The Rotherham investigation highlights why Legionella control needs ongoing attention. Although the source of the reported cases has not been established in the initial reports - read more on the BBC here -, the wider lesson for building operators is clear: effective risk assessment, regular monitoring and properly maintained water systems are essential parts of responsible water hygiene management.
Goodwater works with organisations throughout the UK to assess and manage water hygiene risks, helping them maintain suitable controls and protect the people who use their buildings.
