System Cleaning and Disinfection of Legionella

The Health & Safety Commission's ACOP for 'The control of legionella bacteria in water systems (L8-2001)' specifies that keeping the water system and water within it clean is a key precaution for the control of legionella.

The DEFRA Water Supply (Water Fittings) Regulations 1999, also refers to circumstances where disinfection should be carried out.
