What is the ruling on irrigating crops with treated sewage water?

Question:
We have treated sewage water at the hospital, and we are exposed to this water in many places due to the irrigation of gardens. We may even be exposed to its spray. Is this water ritually impure, such that it invalidates the ablution? And is it permissible to eat the fruits of the trees that are irrigated with it, or not?

Answer:
If this water has been treated until the smell, taste, and color of the impurity have disappeared, and it has become sweet, good, and sound water, then there is no harm in that. It has the ruling of purity. What affects people from it does not harm them. The trees that are irrigated with it are not harmful, and their fruit is permissible.
However, if traces of impurity remain in it, then no, it is not to be used: not for the trees, nor for anything else. Rather, it should be removed to another place where it does not harm the Muslims.
As for if it has been fully treated and the traces of impurity have disappeared from it: no color, no taste, and no smell; then praise be to Allah.
