Are there any drinking water fountains/taps in Paris Charles de Gaulle airport?

I'm not a big fan of spending 3 € for a 250mL bottle of water, hence the question: are there any drinking water fountains/taps in Paris Charles de Gaulle airport, be it airside or at departures/arrivals level? Ideally I would like to either drink directly from the tap/fountain or refill an empty water bottle.

Using the taps in the washrooms at CDG might not be an option, since these dispense tempered (warmish) water suitable for hand/face washing. Moreover they are sensor-activated and provide a relatively slow water flow which could make refilling a bottle a tedious process.

Yes, but not everywhere.

Below is an image of what the water fountains look like at the airport at the time of writing (07/2015):

Apparently, the fountains are used in other airports - but I found another mention of it in this video, which also attributes it to CDG. It is a side view, but it matches up.

I also found this blog post, which says

The fountain (I’ll try to post pictures) was a tall, orange thing with two buttons on each side, like a pinball machine, and instead of a spout, a metal disc with no clear hole. I saw some savvy French woman get a sip, but when I tried I had no luck. I pushed the left button. A blue light turned on, but no water. I pushed the right button. No change. I put my phone down and pushed both buttons. A different blue light went on. I was totally confused, and still thirsty.

Where Are the Fountains

Recent, hands-on experience with the airport show that drinking water can be found in the following locations:

Terminal 2

• Terminal 2D: there is a fountain in the Schengen zone (after security) next to the toilets between gate D54 and D55
• Terminal 2D: there is a fountain in the check-in area (before security) next to the male toilets between desks 9 and 8
• Terminal 2E: there is a fountain between gates L25 and L26 (as of 19 Jan 2019), between M25 and M26 (near Toilets) and between M46 and M47. Also in front of K37 (3 Nov 2022) (EDIT: As of 9 April 2023, the fountain in front of K37 is still there, and there is now a fountain in front of K45 as well. It’s in front of the toilets.)
• Terminal 2F: Working water fountain next to F21.
• Terminal 2F, arrivals floor: inside the entrance to the toilets, near Marks & Spenser Food. There is confirmed water fountain next to La Maison Du Chocolat across F24 (June 2019)
• Terminal 2G: near the toilets
