The need for water hygiene is a basic requirement that most would appreciate. Water should be provided by the relevant water authority in a condition that is acceptable and fit for its purpose. However, once water is distributed into the pipework of a building, its condition becomes the responsibility of the owner / occupier.
In order to meet this standard, there is often a need for plant etc. to be disinfected/chlorinated i.e. cooling towers, cold water storage tanks, domestic water systems, mains supply.
Listed below are some typical examples of when a disinfection should be carried out: -
-
Before the commissioning of new pipework installations
-
Modification to existing pipework
-
Bacterial contamination of a system
-
Sample analysis reveals Legionella presence
-
Water storage tank cleaning as per ACoP L8 / HSG274 Part 2 requirements
-
General maintenance and to maintain hygiene standards
The recognised standard for water system disinfection is BS8558 / PD855468. Wherever possible Envirocure Ltd will ensure this standard is met and will safeguard its compliance with independent verification.
