The diffusion of water from one cell to another is a passive process that doesn't require any ATP.DPD is a diffusion pressure deficit and it was described as suction pressure by Renner in 1915. The DPD is the amount by which the diffusion pressure of water solvent in a solution is lower than that of pure solvent or water and they oppose the diffusion. Water movement occurs from lower DPD to higher DPD.
