finding Public drinking water taps, app or website?

i remember a few years ago a website that listed public water taps that were available, can’t seem to find it again? all of the apps are useless! any info?

Can’t help with the app but cemeteries are a good source…

canal network is pretty good but you may well need a key.

Churches too. Gardeners tap somewhere round the back usually.

I normally sneak into campsites for a cheeky refill.

In some places, water fountains are marked on Open Cycle Maps and there are various websites and apps which use their data…

Any place that serves alcohol has to provide tap water free of charge

Garages?

Only to customers (I think)
