UK Quarterly Project 2026 Q3: Public Toilets and Drinking Water

Nice spot. As noted, the water fountain data seems to come from the Drinking fountains for London project.

Looking at the network traffic while loading that page, the actual data is in a convenient GeoJSON query response.

Is anyone up for asking for re-use?

I’ll have a go at asking. I’ll see if I can ask for re-use of the actual GeoJSON query response and data found on that web page/overlayed map data on that page.

Clicking on the marker seems to give the addresses of the fountains, I imagine it’s unlikely we will add tags for that but I’ll see if I can get clarification whether it’s third party licensed or not.

EDIT: Says it contains OS data, so I imagine the addresses are from OS.

I’m also curious to know how accurate these coordinates are since that would give an indication whether there can be a “straight” import.

EDIT:

Email sent. Now we wait up to 20 working days.

Hi @Robert_Whittaker. Should a working opening_hours:url value be treated as an alternative to a filled opening_hours tag? Node: 13541593252 | OpenStreetMap

It’s useful information, but not as good as having the accurate opening_hours explicitly tagged, since data users won’t be able to automatically determine if it’s open or not.

(Moreover in the specific example you gave, it’s not completely obvious which of the opening times should apply to the toilets. Are they associated with the box office or the cafe?)

For the particular example, the toilets would be open when the centre is open, which depends on events booked. So no fixed hours. Not really associated directly with box office or cafe/bar which may be open too.

Robert pointed me here. I built https://papamap.de, a map of every changing_table=yes in OSM for eleven countries, UK included, coloured by changing_table:location. Green if a dad can reach the table (men’s, unisex or a separate room), red if it’s in the women’s only, grey if nobody has recorded the room yet.

For the UK that’s 2,520 grey out of 2,692. So if you’re surveying toilets for the project anyway, changing_table:location is one more tag worth a look, it takes under a minute on site. Every grey pin links a MapComplete question that asks exactly that.

TfL has a helpful webpage with details of toilets available at each of their stations:

The page also links out to various councils’ pages on toilets.

I noticed Hounslow Council has published their toilets as a CSV under OGL 3 - it’s from 2015 but can it be put into Survey Me/similar?

Am I also right in thinking that the Community Toilet Scheme that is described would be a brand? Or something else

In theory yes, but I’m not sure doing something custom for one small dataset would be worthwhile, particularly as it’s rather out of date. It might be better just to compare the lists manually. If there were any toilets tagged with operator= Hounslow London Borough Council, then you’d be able to see a list at OSM UK Toilets Operator Report .

I’m not sure brand is really the right thing, unless there’s specific branding/signage used at each location. But they could be tagged with access=yes rather than access=customers. It would be good to have some (ideally machine-readable) way to tag that they’re part of a community toilet scheme though to explain the unusual tagging for toilets inside a shop/cafe.

Thank you Rhobert Whittaker .

Got a reply from the Greater London Authority (GLA) about water fountain data and apparently the data comes from Thames Water rather than GLA direct (as it was done in partnership with them), so now we’re awaiting a response from them.

The quarter has now ended. Many thanks to everyone who got involved in this project. There are some graphs showing the progress over the quarter at Toilets Mapping History | Robert Whittaker's OpenStreetMap Stuff . And you can see a longer history of amenity=toilets at amenity=toilets | Tags | OpenStreetMap Taginfo United Kingdom .

Over the quarter the number of amenity=toilets objects increased by over 350, compared with the historical trend of about 175 per quarter. We’ve also seen small increases in the percentage of toilets with various other useful tags added, and the median age-since-last-edit on amenity=toilets objects has dropped by about 6 months.

I’ve settled on network=Community Toilet Scheme for now. Thank you!
