the water supply conduit for each administering of a desired medication to
the supplied water. Each one of the medication administering containers
has an associated control valve coupled to the computer to operate the
associated control valve and facilitate automatic dispensing of the
medication from a desired one of the medication administering containers
into the water supply conduit.
