93.—(1) A duty imposed on a water undertaker under Article 91—
(a)to provide a supply of water to any premises; or
(b)to maintain a connection between a water main and a service pipe by which such a supply is provided,
shall be owed to the consumer.
(2) Where a duty is owed by virtue of this Article to any person, any breach of that duty which causes that person to sustain loss or damage shall be actionable at the suit of that person; but, in any proceedings brought against a water undertaker in pursuance of this paragraph, it shall be a defence for the undertaker to show that it took all reasonable steps and exercised all due diligence to avoid the breach.
