Title: Map of water sources
Post by: Frank9755 on 26 June, 2019, 09:53:16 am
I came across an online map that showed where you could find water sources, such as churchyards in France.  I can't find it now and it is impossible to search for.  Anyone know what it is called?

There's one here (https://www.eau-cyclisme.com/) but it's a bit sketchy.  Most of the ones I use aren't on it.

Paris only: https://www.data.gouv.fr/fr/reuses/carte-des-points-deau-public/

I googled points d'eau en france

The Open Streetmap cycling maps have a lot of water sources marked.

I've been using Osmand with the POI overlay of drinking water. Unfortunately my most recent map update broke something. I've reported it as a bug to Osmand, but not heard back.

Most (but not all) churches have a tap round the back for flowers.  Saved me from dehydration once.

I spent a night in northern France looking round the backs of a few churches to no avail!  Was amused to see that some of them had other tyre tracks already there.  Eventually found what must be the only bakery in France that opens at 4am on a Saturday

Something I picked up from a Swede who did the TCR last year, many gas stations, even self service ones, and closed ones, have a tap, but they usually have the handle removed. However, you can get a universal key thingy that will work with these taps:

https://www.biltema.se/bygg/vvs/vvs-verktyg/universalnyckel-till-vattenutkastare-2000034155

The one I have is made of a plastic, pretty light, and just sits in my tool bag. Been useful a couple of times for getting water from a tap that has no handle.

That is correct, I found a couple of petrol stations with headless taps in France.  Common in Australia too.
I don't remember it being an issue elsewhere in Europe besides France so not widespread enough that I'd carry a brass tap head but a plastic one would be better.

Or you can use the adjustable spanner in your bike tool kit, which is also useful for wheel nuts, lockring tools, truing brake rotors, tighting light/mudguard/rack nuts, miscellaneous BSO repairs, applying ham-fisted monkey force to RADAR keys in stiff locks, clamping tent pole elastic while replacing sections, bleeding radiators in freezing bunk barn shower rooms, clobbering small animals to death, and could - in emergency - serve as a 2000A slow-blow fuse.

Matthew came to this thread expecting a completely different topic of conversation. For me, professionally, water sources are rivers, reservoirs and aquifers (chalk, gravels and greensands) and the associated water treatment works.

In France a lot of small communes have put in (or are putting in) camping-car services which have water supplies (and places to empty the chemical loo you carry on your rear carrier) which should be free access. I haven't tested one yet but I have often passed by and wondered.

To be fair, drilling into an aquifer is probably the easiest way to refill your bidon in parts of the East Midlands on a Sunday afternoon...   :D

In a probably-not-frequent-enough example of Sustrans catering to the needs of the non-cyclists on bikes they're supposed to be for, the Bristol-Bath Railway Path has drinking fountains at various points along it. As a cyclist I never need them, and arguably this path is well catered for without them (two cafes and a few pubs on the route not to mention a city at each end), but it's easy to forget how thirsty non-cyclists get on bikes in summer. Which is admittedly a bit of a diversion from the point of the thread.

So, after much digging around with the data files of the maps, and inspection of the internals of OSM. I've found the bug, and a temporary work around.

It seems that drinking water on OSM has been reclassified from Sustenance, to Man made. Meaning that the search doesn't work as obviously as you'd expect. If you do a POI search for "man made drinking water", it works. It's a bodge, I'll see if I can find someone to make a proper fix asap. As soon as we can work out if this is a bug with OSM (i.e. it should be sustenance), or a bug with osmand (it should be man made...) *sigh*

According to this there is no refill option or other drinking water in a radius of at least 100kms around me. That's fine by me, don't visit the Limousin, it's a desert!  ;D ;D

Limoges, (France!) 45°49'53"N 1°15'28"E  (according to internet).

I know there is water - except on the Plateau de Millevaches where it costs so much the locals refuse to connect to the supply; normal, they have one of the highest rainfalls in France!

We rather head for the graveyard, which is sometimes near the church, sometimes not! There is always a tap in graveyards, only problem is that the gates may be locked.

I would not put too much trust in OSM for water sources judging by this map! I would need it on a much larger scale to really identify the spots (and since I am not expert at manipulating this sort of thing I am not going to try; I may ask for some lessons from Phil, it's her profession) but there is a big splodge on a road junction that is without any sort of structure apart from a roundabout and is also not accessible to cyclists (or tractors and herds of limousines). There is also the municipal rose nursery and a sport and culture complex next to a river (which is well off any useful route). I don't see any of the likely churches, graveyards or similar. There is also not the pump at Couzeix which features on another net water source directory and which is almost certainly unusable.

Yes, OSM, by it's very nature is only as good as it's data input, which is all the work of volunteers. I don't know if a water tap attached to a building would be added as a drinking water POI. So graveyards churches etc... May not be included.

Round these parts the issue I find is that waternet are installing taps faster than I can add them to OSM
 I added two in Amsterdam I found earlier this week. I thought I'd found them all, but these two were new.

As with anything, YMMV, don't rely on any one source, just cos it's on the map, doesn't mean it's working, possession of this map doesn't grant you right if way, your investment can go down as well as up...

Do they do the ZapMap thing of having a discussion thread associated with each source?  That works around a lot of the "it's broken in $annoying_way[1]", "you need a $special_key" or "the gates are locked at weekends" type issues that never fit neatly into pre-defined GIS fields.


[1] Okay, there's a lot more to go wrong with an EV charging point than a water tap, but the principle applies.

While out today and in desperate need of a bottle refill (the decision had already been made to stop at the hyper in the next town) I came across a really useful tap, by the side of the road, completely free access, over a drain grate so there was no surrounding bog and giving just enough on the automatic plunger tap to fill up a 800ml bottle. What's not to like????
This may well be a camping-car point, it was next to a parking place (more than a layby because there was a screen of shrubs between it and the road). I will have to check out a few more camping-car points, this wasn't signaled as such, to be certain, but if true then one of the most useful water source maps for tourists in France could well be the map of camping-car points (I can't believe it doesn't exist, just a question of finding it).

QG how do I go about adding such points to OSM, being a complete ignoramous in such matters? I am assuming that Googlemaps can give me a GPS reference for the point. Can I just send it to you/post it here and let you do my dirty work or do I have to muddy my brain with this "informatique" stuff? Or should this be a thread fork?

To complete the tale, with road temperatures close to 40° and having nearly finished my second bottle in 20kms I called out the recovery wife. I couldn't face the heat and crossing Limoges (which would have taken a certain while at 10km/h). In the 10 minute ride home 1l of fizzy mineral water went down. After a certain point in heat my body refuses to assimilate "ordinary" water (which then slops about in my tummy, most unpleasant!). The fizzy water came with the recovery team, needless to say. I took my cue from an ex-clubmate (a very experienced randonneur) who dehydrated and finished in hospital on a 1000km BRM the other week.

Round here the answer is yes. Today I was outing walking an off road half marathon course my wife will be running in two weeks.  She was making route notes as it will be unsigned and we were also looking for water sources as many streams are dried up the moment due to lack of much recent rain. We wandered round a church and eventually located a water tap as well as a water butt.  I marked their exact position on OSM when we got back. Of late I've marked about 8 drinking water sources round here. Some I've subsequently taken advantage of on overnight DIY audaxes where other options are not available.  OSM also has the ability to record  spring water sources. In fact most things can be recorded through the tag system.

I still don't have an account with OSM but I have now found a resource for campingcar points for France: https://en.airecampingcar.com/

Click on the relevant region and follow the dropdowns for the department. This is only a listing by postal address. Some are obvious others not so, it depends on your geographical knowledge. However at 25 points per dept it is useful. It makes no claims to being complete, only as good as the owners (not users, I think) giving their details.

On my route checking today I had a look at one site off this source. The water was there and available 24/24 - but it wasn't free! 2€ for 40l of water and 30 mins of electricity. It might do for an entire club! Other weakness, you need a qr hose coupling to get the water. Obviously some sites have to be at least self-supporting!
