Cleans and Disinfectants
British Standard 6700
This standard relates to new domestic pipework installations and states that new installations or modifications should be disinfected as part of commission cleaning 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.

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.
This approach to the cleaning and disinfection of cooling towers is taken whenever possible by AMES water treatment service technicians. Where it is not reasonably practicable, AMES Water Treatment have developed a specialised range of products for this application.
Shower heads act as filters, trapping debris and scale. These act as a nutrient and a safe habitat for bacteria. It is therefore vital that showers are cleaned on a regular basis as part of an overall legionella control programme.
