Water Hygiene and Disinfection

Providing Quality Service Nationwide

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.
