The cleaning and disinfection of water systems on a regular basis is vital if hygienic conditions are to be maintained and is a service that B & V have considerable experience in. There are currently two standards that relate directly to this subject.

1. British Standard 6700

This standard relates to new, domestic pipework installations, and states that new installations or modifications should be disinfected before being placed into service. The method to be used is set out in the standard, detailing the contact times and disinfecting agents to be used. Heating, ventilating and pipework contractors that use our service will have the disinfection certificated on completion of the work and before the building is placed into use.

2. Legionnaires disease' 'The control of legionella bacteria in water sytems' ACOP (L8)

The H.S.E. Code of Practice relates to the control of legionnaires disease and recommends that as part of a complete maintenance and management scheme that regular cleaning and disinfection of the following equipment is carried out:                                                                                    

• Cold water storage tanks and down services
• Hot water calorifiers
• Cooling towers and evaporative condensers
• Air humidifaction plant
• Water outlets and shower heads
• Water features
• Misting systems

The frequency of cleaning and disinfection  is twice annually for cooling towers and once per annum for hot and cold water services. Other systems will have the frequency established in the Risk Assessment and Logbook but in general is dependant on the risk of the system and the potential for contamination.

Please contact us at sales@bvwater.co.uk for further advice on keeping your equipment clean and free from legionella.
