Charges and other terms for services provided by Authority
22.—(1) The Authority may make, in relation to any service provided by the Authority, a scheme or schemes for determining either or both of the following:
(a)
the charges which (save in so far as they are the subject of an agreement between the Authority and a person availing himself of the service) are to be made by the Authority; and
(b)
the other terms and conditions which (save as aforesaid) are to be applicable to the service.
(2) A scheme made under this section may make different provision for different cases or classes of cases determined by, or in accordance with, the provisions of the scheme.
(3) A charge exigible by virtue of this section may be recovered by the Authority in any court of competent jurisdiction as if it were a simple contract debt.
(4) A scheme or any amendment thereof made under this section shall come into operation on such date as may be determined by the Authority.
(5) Nothing in this section shall be construed as prohibiting the Authority from levying any charge or collecting any dues for anything done or any service rendered by reason only of not being incorporated in a scheme and the rates, charges and fees payable to the Authority for any service rendered shall be in accordance with such rates, charges and fees as may from time to time be determined by the Authority.
(6) The rates, charges and fees applied by the Authority immediately before the appointed day shall continue to be valid as though determined by the Authority under this section until rescinded, varied or otherwise determined by the Authority.
