Water Hygiene / Legionella Control
Monitoring & Maintenance

Regulations require employers to monitor and maintain domestic hot and cold-water systems to reduce the risk from legionella bacteria. The employer should keep suitable records of the tasks carried out and they should be reviewed at least annually.

Hot and cold-water systems include cold-water tanks, calorifiers, water heaters, showers, Thermostatic Mixing Valves, expansion vessels etc. These need to be regularly inspected for temperature, cleanliness/operation and the water should be kept moving through the water system, so it does not stagnate.

Following a Legionella Risk Assessment and the production of a Written Scheme, this should detail the required control scheme that should be implemented and followed to maintain a safe water system. C&S Water Treatment Ltd will follow these documents to ensure a bespoke control regime is implemented. All our team are trained to City and Guilds standard and are regularly checked for competency.
