Swimming pools, saunas and wellness
Legionella at your pool or sauna: every shower and every foot bath flushed, with time, name and result in one logbook.
This is about the showers and taps, not the pool water itself. A tag per shower, a sensor on the water heater of the pool hall, and the closed season of the outdoor pool as a period in the planning.
Your situation
What makes a swimming pool difficult
The showers run all day, but not all of them: a shower block on the quiet side sometimes stands still for days.
Women's and men's shower blocks
Every shower gets a tag and is listed separately in the logbook. The walking route goes per block, and anything left gives an alert.
The outdoor pool in the closed season
Outside the season the outdoor showers stand still. That closed season is a period: closed and drained, and an extra round past all showers on reopening.
Foot baths and the staff shower
A foot bath is cold water that is rarely refreshed; the staff shower runs once per shift. Both get a tag and a place in the weekly round.
A sauna with its own showers
The showers at the sauna are their own group in the planning, with the opening hours of the sauna.
How it works
Four steps, one line in the logbook




- 1
A tag at the tap
At every tap in the flushing round you stick a tag on the tile, like at shower 5 in the women's showers. One labelled bag per building; at the first tap you tell the app which tap it is.
- 2
Phone against the tag
Whoever flushes holds the phone against the tag and opens the tap. A timer on the screen counts down the flushing time of your site, one minute by default.
- 3
The sensor sees the hot water
The sensor on the hot pipe leaving the water heater (water heater pool hall), before the first branch, measures every 15 minutes and sees the hot water within that interval. Taps on the same installation together form one flushing round.
- 4
The line is in the logbook
Half an hour after the last tap the round closes. For each tap there is the time, the name and the result; if no hot water came, that is in it too, with an alert.
What you see
Three screens from the app
With made-up data, as it will look for you.
The temperature chart
The course of the day for each sensor. The jump when flushing shows that hot water came out of the installation.
The line in the logbook
Every flush with time, name and result. Nothing can be changed afterwards; a correction is a new line.
The report
Key figures, findings and the results per flushing point, for the period the inspector asks for.
Everything it does
What is in it now
Walking route per shower block
The weekly round is a list per changing room or shower block on the phone; a tapped shower drops off the list.
Closed season for the outdoor pool
Closed and drained outside the season, as a period on the outdoor pool group. On reopening the extra round is ready.
Flushing without an account
Staff tap with their own phone and the flushing password of the site. Their name is on every flush, and they do not need an account.
Alerts
A temperature outside the norm (after 3 readings in a row) or a flushing round that is not done gives an alert in the app and an email to whoever is responsible on site.
Report with one click
PDF, Excel or CSV over a period of your choice, and a share link for the inspector that works for 24 hours.
The laboratory still takes the samples
The laboratory results, the risk assessment and the water safety plan go into the same file as the logbook.

Who puts it up
Your maintenance team, in half an hour
The sensor goes on the hot pipe leaving the water heater of the pool hall, before the first branch; with a separate water heater for the sauna or the outdoor pool, a second one. You plug the gateway in at the till; you stick the tags on the tile at every shower.

The laboratory still takes the samples
We record the flushing in between. The laboratory results, the risk assessment and the water safety plan go into the same file.
