Running a swimming pool means giving people access to water, and the duty of supervision grows with every metre of poolside. A child drifting unnoticed into the deep end, or a dive from the tower that goes wrong, can threaten the whole operation. On top of that come chlorine storage, filter plants and a season in which every lost day eats into turnover.
Are we automatically liable if something happens in the pool?
Not automatically, but quickly. Parents and adult guests carry a share of their own responsibility, but as soon as supervision, signage or water quality fell short, the operator's duty of care applies. After a drowning incident or a fall from the slide, the sums involved are ones a single pool could never carry on its own. Public liability insurance investigates the claim, pays justified ones and defends against unjustified ones.
What goes wrong in this trade
01
Drowning and near drowning
A single unwatched moment at the non-swimmers' pool or in the toddlers' area can turn life threatening within minutes. This is the most serious risk in running a pool.
02
Falls from the diving tower and slide
A dive into water that is too shallow, a collision at the bottom of the slide, a slip on wet tiles: spinal and head injuries are not unusual here.
03
Water treatment and chlorine
Chlorine gas or chemical incidents in the plant room endanger staff and sometimes guests, and can bring the whole operation to a halt along with regulatory action.
04
Filter and pump failure
If water treatment fails, the pool must close until the readings are right again. Spare parts for older plants often take a long time to arrive.
05
Weather at outdoor pools
Hail and storms hit pools, sunbathing lawns and outdoor plant directly, and a wet summer also hurts turnover.
06
Staff in and around the water
Lifeguards work under a heavy duty of supervision themselves, perform rescues under time pressure and are exposed to accidents and psychological strain in the process.
07
Hygiene and water quality
Contaminated water or an outbreak of infection among guests can lead to closure by the health authority and raise questions of liability.
Covers injuries to guests from drowning, falls and slide accidents; given the risk of lasting harm the sum insured should be well above standard levels.

What it costs: example prices
Premiums vary sharply between a small club-run pool with one basin and a leisure pool with several slides and a diving tower. Visitor numbers, staffing and turnover drive the rating, and differences of several hundred per cent between quotes are common.

Practical tips from your broker
Choose at least 10 million euros of cover for bodily injury, since after-effects from drowning or head injuries can run for decades.
Have the duty of supervision and the staffing level for each basin described expressly in the policy, otherwise a claim can turn into a dispute over whether it was met.
Have the chlorine store expressly included in both building and liability cover, it is one of the biggest single risks in running a pool.
Keep thorough records of water samples, maintenance logs and rescue drills: after a claim this is your most important evidence that you met your duty of care.
Set the indemnity period for business interruption to at least 12 months if spare parts for the filter plant have long delivery times.
Check whether seasonal staff and volunteer supervisors are covered through group accident insurance; the statutory accident insurer only covers accidents at work.

Frequently asked questions
Questions and answers
Does a swimming pool need compulsory insurance?
There is no nationwide legal requirement,
but municipalities, clubs and operators almost always require public liability cover with a high
sum insured internally, because a single serious accident can exceed all of a pool's equity.
Is the pool liable if parents were not watching?
Parents' own responsibility does not automatically release the operator.
As soon as a failure in supervision, signage or water quality can be shown,
the pool's duty of care applies regardless of what the parents did or failed to do.
What does insurance for a small outdoor pool cost?
Public liability for a small club-run pool is often between 60 and 200 euros a year.
A municipal indoor pool with staff and several basins usually pays 800 to 2,500 euros.
Are lifeguards covered at the pool?
Employed lifeguards are covered through public liability and the statutory accident insurer.
Volunteer supervisors need extra cover, for example through group accident insurance.
Does insurance pay after a chlorine incident?
Bodily injury and property damage from a chemical incident are covered by public liability
insurance, provided the chlorine store is expressly included.
Damage to the plant itself belongs under machinery breakdown cover.
Do I need to keep insuring the outdoor pool over winter?
Yes, the building, basins and plant need protection against frost,
storm and burglary even outside the season, even when there is no bathing operation.
