Water sources are included in the Open Street Map cycle maps, although you need to zoom in to see them. They're included as Points Of Interest when you download the OSM cyclemaps from openfietsmap.nl to your Garmin GPS.
You can sometimes use the bathroom sinks at places with public restrooms like grocery stores, although they often lack the space to accommodate a water bottle.
