(1)Where—
(a)the functions of a water authority immediately before the transfer date include, by virtue of any local statutory provision, any functions of a navigation authority, conservancy authority or harbour authority; and

those functions shall become functions of the Authority on that date.
(2)Subject to the power conferred by section 191 below, on and after the transfer date every local statutory provision relating to a function transferred by this section and everything done by or in relation to a water authority under any such provision shall have effect, so far as may be necessary for the purposes of, or in connection with, the transfer of functions made by subsection (1) above, as if—
(a)any reference in any such provision to a water authority were a reference to the Authority; and
(b)any such thing had been done by or in relation to the Authority.
