Legionella risk analysis for swimming pools

You are required to prevent the formation of Legionella if you operate a publicly accessible pool such as:

• swimming pool
• swimming pool in, for example, hotels, saunas, and camping sites
• medical bathing facility (pool)
• children’s paddling pool

Legionella risk analysis

You must ask a BRL 6010-certified consultant (in Dutch) to conduct a risk analysis. If the analysis indicates that there are risks, you must:

• have a Legionella management plan (in Dutch) drawn up by a BRL 6010 certified company and follow its guidelines. this includes for example:

  • where your tap water comes from and what the quality is
  • which taps should be tested regularly
  • the results of the risk analysis
• maintain a logbook recording the measures you take to prevent the formation of legionella
• perform a water check at least 2 times a year

You must have a risk analysis carried out before you open your swimming location, and within 3 months after changing a water installation. The risk analysis and your management plan must be available for inspection at the pool site. The provincial authority can request access to your management plan and logbook. You can use the Dutch-language Legionella prevention tool to see which measures against Legionella you can take.

Reporting Legionella

Does the water check indicate 100 colony-forming units of Legionella per litre (cfu/l) or more in the bathing water? Then you must report this to your provincial authority as soon as possible. You do this via the online service counter Omgevingsloket (in Dutch).
