PART 2 WORKS PROVISIONS

Supplemental powers

21 Discharge of water
1 The undertaker 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 transit system is authorised to be laid, make openings into, and connections with, the watercourse, sewer or drain.
2 Any dispute arising from the exercise of the power conferred by paragraph (1) to connect to or use a public sewer or drain is to be determined as if it were a dispute under section 106 (right to communicate with public sewers) of the Water Industry Act 1991.
1991 c. 56. Section 106 was amended by section 35(1) and (8) of, and Schedule 2 to, the Competition and Service (Utilities) Act 1992 (c. 43), sections 36(2) and 99 of the Water Act 2003 (c. 37) and paragraph 16(1) of Schedule 3 to the Flood and Water Management Act 2010 (c. 29).
3 The undertaker must 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 must not be unreasonably withheld.
4 The undertaker must not make any opening into any public sewer or drain except—
(a) in accordance with plans approved by the person to whom the sewer or drain belongs, but such approval must not be unreasonably withheld; and
(b) where that person has been given the opportunity to supervise the making of the opening.
5 The undertaker must 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.
6 The undertaker must 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.
7 Nothing in this article overrides the requirement for an environmental permit under regulation 12(1)(b) (requirement for environmental permit) of the Environmental Permitting (England and Wales) Regulations 2010.
