If you go into the detailed explanation (and can read French) they do have some hydraulic pumping included in their "batteries" section.

In their 100% renewables scénario on a peak consumption (105gw) hour and peak energy production (sun at zenith) they would store the excess production like such:

• 7.2gw to water pumping
• 22gw to static batteries
• 2gw back to the grid (chatting electric vehicles I guess).

Also even in their most nuclear scenario (50% nuclear, 50% renewables) they still include 7.2gw of water pumping.

I'm curious of why you put so much value in water pumping? As a Quebecois I have a small notion of how disruptive (flooding of vast areas of land, massive amounts of concrete, dead rivers downstream of the dam ) water reservoirs for hydroelectricity can be and I have a hard time imagining a viable way of relying extensively on that technique.
