Incorrectly managed or installed water systems and pipework can provide the necessary growth conditions for Legionella and other bacteria. The first step in a sound water hygiene program is a Legionella Risk Assessment which will assess the system and advise remedial actions to correct any issues found. A Control Scheme will then be put in place to manage and record the required monitoring and sampling programs.
