Water density and compressibility
Water is compressible, but it takes a lot of pressure to increase the density by 10 or 20%
Deep Ocean pressure measurements
Pure water would have a density of 1205.154 kg/m3 at pressure = 1086 bar
1086 bars (15750 psi) from en.wikipedia.org/wiki/Mariana_Trench
or a density of 1100 kg/m3 at pressure at 263.835 bar, which is about 20% higher than the pressure in a PWR.
Salt water has a maximum density of ~12700 kg/m3.

Was there a question in there?

That's one reason water is used as a hydraulic fluid. Add a little anti-bacterial and presto! Water is also under immense pressure in the lithosphere. Leucogranites form when expelled water melts its new host rock environment - found in places like Tibet. My home state of Texas sits ontop of North America's 3rd largest aquifer - the Gulf Coast aquifer, formed from high pressures of slumping mud wedges going into the Gulf of Mexico basin.
