Every swimming pool, hotel pool, water park and jacuzzi must test its water regularly under the Regulation of the Minister of Health of 9 November 2015. MICHLOR collects samples on site, sends the analyses to a PCA-accredited laboratory and compiles documentation ready for a Sanepid inspection. You get the result and the report, not the problem.
Water that looks clean can still exceed microbiological limits you cannot see with the naked eye (and that is where most of it happens). The Ministry of Health regulation splits the requirements into two groups: microbiological parameters tell you whether bathing is safe for health, and physicochemical ones tell you whether treatment and disinfection are working properly. Both sets are tested, regularly and in an accredited laboratory.
Regulation of the Minister of Health of 9 November 2015 on the requirements for water in swimming pools
Consolidated text: Journal of Laws 2022 item 1230. In force in 2026. It does not apply to pools filled with medicinal waters.
We match the scope to the type of facility, so you do not pay for parameters your basin does not need. The analyses are carried out by a PCA-accredited laboratory using the reference methods from the regulation.
Frequency is where inspections most often catch facilities out. The regulation separates routine measurements, taken by the operator, from laboratory testing. Below are the minimum frequencies for a standard basin.
| Parameter | How often |
|---|---|
| pH, redox, free chlorine, temperature (routine measurement) | at least every 4 hours |
| Combined chlorine (routine measurement) | at least once a day |
| Escherichia coli, Pseudomonas aeruginosa | twice a month |
| Total viable count, oxidisability | once a month |
| Legionella sp. — standard basin | 4 times a year |
| Legionella sp. — jacuzzis and basins generating aerosol | 12 times a year |
| Trihalomethanes, chloroform, nitrates | once a quarter |
| Cyanuric acid (where used) | 4 times a year |
Outdoor pools: at least 3 tests per season, and during long spells of hot weather at least twice a month. Basins used for infant swimming lessons are tested more often. The schedule is agreed with the relevant sanitary inspector, and MICHLOR helps you draw it up in line with the regulation.
The regulation covers every publicly accessible basin, whatever its size.
This is a distinction no competitor's price list explains, and it can decide the outcome of an inspection. One building holds two different water systems, and an inspection may check both.
Water in the pool basin is covered by the 2015 regulation (microbiology, chlorine, Legionella in jacuzzis). Drinking water and internal plumbing is covered by the Act of 13 March 2026 amending the Act on collective water supply (Journal of Laws 2026 item 605), which lists hotels and tourist facilities as priority premises and requires a risk assessment of the drinking water system (Legionella, lead) by 30 June 2028.
More about the new obligations: Legionella: the building owner's obligations in 2026. Ongoing oversight is provided by water monitoring for businesses.
We establish the type and number of basins, their temperatures and whether there are jacuzzis and showers. We then propose a scope of testing and a schedule compliant with the regulation.
We come to your facility in Warsaw or Mazovia and collect samples following the correct procedure. Where, when and how a sample is taken has a real effect on the result.
We commission the testing from a PCA-accredited laboratory using reference methods. Accreditation is the condition for Sanepid to accept the result at all.
You receive the analysis report and a complete set of documentation ready for the sanitary inspector. Where a result exceeds a limit, we advise on corrective action or carry out disinfection.
Routine measurements (pH, free chlorine, redox, temperature) are taken every 4 hours during opening times, and combined chlorine once a day. Laboratory testing: microbiology once or twice a month, Legionella 4 times a year for a standard basin and 12 times a year for a jacuzzi, and trihalomethanes and nitrates once a quarter.
Yes. The obligation follows from the Regulation of the Minister of Health of 9 November 2015 (consolidated text, Journal of Laws 2022 item 1230) and applies to every publicly accessible swimming pool, hotel pool, water park and jacuzzi. The results are submitted to the state sanitary inspector.
Microbiological: Escherichia coli, Pseudomonas aeruginosa, total viable count, and in jacuzzis and showers also Legionella. Physicochemical: pH, free and combined chlorine, redox potential, turbidity, trihalomethanes, chloroform, nitrates, oxidisability, and aluminium where a coagulant is used.
Yes. Pool water analyses must be carried out by a laboratory accredited by the Polish Centre for Accreditation, using the reference methods set out in the regulation. Only such a result will be accepted by Sanepid. MICHLOR works with an accredited laboratory.
The price depends on the number of basins, the range of parameters and how often testing is done. A quarterly set of trihalomethanes costs one thing; monthly microbiology or 12 Legionella determinations a year in a jacuzzi costs another. We prepare an individual quote once the configuration of your facility is established, usually within 24 hours.
Corrective action must be taken and the test repeated. Where Legionella or microbiological parameters are exceeded, the system usually has to be disinfected and a follow-up analysis carried out. MICHLOR does both the testing and the disinfection, so you solve the problem with a single contractor.
Do you run a swimming pool, a hotel with a pool or a spa area? We will take care of the water testing, from sampling through to the documentation for Sanepid. Tell us about your facility and we will prepare a quote.
We work across Mazovia, Łódź, Podlasie and the Lublin region. We reply the same working day.
