If the fountains don't have identifiers that are suitable for ref, you may be able to add them to wikidata (if they are 'notable' enough for that project and you have permission to add them to a cc0 licensed project). You can only do that for fountains that YOU have added yourself though, you can't add them to wikidata if someone else mapped them, due to license incompatibility between ODBL and cc0.
