      The preventative maintenance plans currently in place for the prevention of Legionella are viewed by owners of tap water installations as complicated, inaccessible and too elaborate. The general attitude of owners is that they have not received sufficient information on the risks, obligations and responsibilities covered in the management plans. Owners do not personally study the regulations in detail but hire external advisors for this purpose. However, the quality of the advice provided by such advisors differs greatly. These conclusions represent the outcome of a study carried out by Kiwa Nederland BV (Kiwa) and National Institiute for Public Health and the environment (RIVM) among employees of water supply companies who monitor compliance with the regulations for the prevention of Legionella. The 22 experienced inspectors who were interviewed in the study provided a second-hand interpretation of the view of the owners of tap water installations. In 2004, the Inspectorate of the Ministry of VROM and the water supply companies reached an agreement on how such inspections should be carried out. The procedures to be followed were formally laid down in the Inspection Guidance 2005. As such, the water supply companies are required to inspect - at least every 3 years - all tap water installations that are connected to their respective company and which fall within the scope of the regulations for the prevention of Legionella. The most important recommendations for improving current practice are to execute the regulations in a manner that is more tailor-made to the specific situation and to provide more and better information to the owners of tap water installations. Additionally, professional qualifications should be established for the advisors, and the user-friendliness of the preventative maintenance plans should be improved. The recommendations of this report are taken into account in the 2009 revision of the 'Drinking Water Decree' subdivision 'Prevention of Legionella'. Within the framework of the 'Intervention Strategy Prevention of Legionella', initiated in 2009, the Inspectorate of the Ministry of VROM will intensify the communication of information to the owners of tap water installations.
