The promoter may use any watercourse or any public sewer or drain for the drainage of water in connection with the construction, operation or maintenance of the authorised works and for that purpose may lay down, take up and alter pipes and may, on any land within the Order limits, or in any street along which the authorised street tramway is authorised to be laid, make openings into, and connections with, the watercourse, sewer or drain.

Any dispute arising from the exercise of the power under paragraph (1) to connect to or use a public sewer or drain shall be determined as if it were a dispute under section 106 of the Water Industry Act 199123.

The promoter shall not discharge any water into any watercourse, public sewer or drain except with the consent of the person to whom it belongs; and such consent may be given subject to such terms and conditions as that person may reasonably impose but shall not be unreasonably withheld.

The promoter shall not, in the exercise of the powers conferred by this article, damage or interfere with the bed or banks of any watercourse forming part of a main river.

The promoter shall take such steps as are reasonably practicable to secure that any water discharged into a watercourse or public sewer or drain under the powers conferred by this article is as free as may be practicable from gravel, soil or other solid substance, oil or matter in suspension.

This article does not authorise the entry into controlled waters of any matter whose entry or discharge into controlled waters is prohibited by section 85(1), (2) or (3) of the Water Resources Act 199124.
