I wonder what engineering challenges are involved in this. I'd imagine it's more complicated than just digging a bigger hole and adding more water filters

  Every 10m of depth adds about 1 atm of pressure. Not sure what challenges specifically that introduces though.

    Leaks. Water at those pressures finds holes, opens cracks and eats away at foundations. A little trickle quickly becomes a sinkhole, or your structure starts to float away. It all depends on the soil.

    148 ft of water is ~64 psi (4.4 bar). Challenges are probably not so big once the thing is constructed. External earth and groundwater pressure offsets internal water pressure I would assume and the real challenge is actually designing for when the thing is empty so that it doesn’t fail due to external loads. Lots of this is dependent on geology of the adjacent soil and geometry of the hole. Pictures seem to show sheet piles so we know it’s soil.
