When the water potential gradient evens out, so that the water potential on eithersides of the partially permeable membrane is equal. Also, when something is placed in an isotonic solution ( a solution with the same waterpotential as the organism contains)
Your cells are in an isotonic environment.

Red blood cells are in osmotic equilibrium with their surrounding environments. If they swell or shrink too much, their membranes will rupture, leading to cell damage and potential cell death.
Osmotic equilibrium refers to the state where there is no net movement of water across a semipermeable membrane due to an equal concentration of solute on both sides. This balance prevents further water flow and maintains stability in the system.
An osmometer measures the concentration of solute particles in a solution. It does this by determining the osmotic pressure, which is the pressure generated by the movement of solvent molecules across a semipermeable membrane to achieve equilibrium.
Osmotic thirst is triggered by an increase in the concentration of solutes in the blood, which leads to a shift in fluid balance within the body. This type of thirst occurs when there is an imbalance in the osmotic pressure between the intracellular and extracellular fluid compartments, causing the body to seek out water to restore equilibrium.
Sodium is necessary for the osmotic equilibrium.

When demand equals supply.
Osmotic pressure is the pressure that develops when water moves across a semi-permeable membrane to achieve equilibrium in solute concentrations between two solutions. It is dependent on the concentration of solute particles in the solution and temperature.
