Is it permissible for an owner to divert their water through another's designated small canal (Saaqiyah) to share in a benefit elsewhere?

Primary text

It is not permissible for one owner to run their water through another's small canal to share in water division at another point unless the other owner consents. This is prohibited because the first party would be acting upon the property of another, damaging its edge without permission, and mixing their right with another's right in an indistinguishable manner.
