100.—(1) Subject to the following provisions of this Article, a water undertaker may disconnect a service pipe which for the purposes of providing a supply of water to any premises is connected with any water main of that undertaker, or may otherwise cut off a supply of water to any premises, if the occupier of the premises—
(a)is liable (whether in his capacity as occupier or under any agreement with the undertaker) to pay charges due to the undertaker in respect of the supply of water to those premises; and
(b)has failed to do so before the end of the period of 7 days beginning with the day after he is served with notice requiring him to do so.
(2) The power conferred by paragraph (1) is not exercisable in relation to any premises specified in Schedule 2.
(3) Where—
(a)a water undertaker has served a notice for the purposes of sub-paragraph (b) of paragraph (1) on a person; and
(b)within the period of 7 days mentioned in that sub-paragraph, that person serves a counter-notice on the undertaker stating that he disputes his liability to pay the charges in question,
the undertaker shall not in respect of that notice exercise his power by virtue of that paragraph in relation to any premises except at a time when that person is the occupier of the premises and those charges are enforceable against that person in a manner specified in paragraph (4).
(4) For the purposes of paragraph (3) charges are enforceable in a manner specified in this paragraph against a person if—
(a)the undertaker is able to enforce a judgment against that person for the payment of the charges; or
(b)that person is in breach of an agreement entered into, since the service of his counter-notice, for the purpose of avoiding or settling proceedings by the undertaker for the recovery of the charges.
(5) A water undertaker which exercises its power under this Article to disconnect any pipe or otherwise to cut off any supply of water may recover, from the person in respect of whose liability the power is exercised, any expenses reasonably incurred by the undertaker in making the disconnection or in otherwise cutting off the supply.
(6) Where—
(a)a water undertaker has power under this Article to disconnect any pipe to any premises, or otherwise to cut off any supply to any premises; and
(b)a supply of water is provided to those premises and to other premises wholly or partly by the same service pipe,
the undertaker may exercise that power so as to cut off the supply to those other premises if and only if the same person is the occupier of the premises in relation to which the charges are due and of the other premises.
