New data on the state-to-state rate coefficients for collisional transitions for H$_2$O and H$_2$ molecules are used in the calculations. The results of ortho-H$_2$O level population inversion calculations for the 22.2-, 380-, 439-, and 621-GHz transitions are presented. The ortho-H$_2$O level population inversion is shown to depend significantly on the population distribution of the para-H$_2$ $J = 0$ and $2$ rotational levels.
