1(1)For the purpose of exercising their functions under the enactments mentioned in section 37 (1) of this Act, the Greater London Council may construct a public sewer—
(a)in, under or over any street, or in or under any cellar or vault below any street;
(b)in, on or over any land not forming part of a street; and
(c)in, under or over the bed, banks or shores of the River Thames.
(2)Where the Greater London Council propose in the exercise of their powers under this paragraph to construct a sewer which will cross or interfere with any watercourse or works vested in, or under the control of, a land drainage authority other than the Council or the council of a London borough or county district, they shall before adopting plans for the construction of the sewer give notice of their proposals to that authority; and if that authority within twenty-eight days of the giving of the notice to them serve on the Greater London Council notice of objection to the proposals, the Council shall not proceed with the proposals unless all objections so made are withdrawn or the Minister after a local inquiry has approved the proposals with or without modification.
(3)Section 31 (2) of the Land Drainage Act 1961 (which requires the consent of a river authority to the erection, alteration or repair of structures in, over or under watercourses) shall not apply to any work executed under this paragraph.
(4)The foregoing provisions of this paragraph shall not be construed as exempting the Council from compliance with any relevant requirement imposed by or by virtue of section 279 or any other provision of Part XII of the Public Health Act 1936 or by or by virtue of the Public Utilities Street Works Act 1950.
(5)Except where notice has to be given by the Greater London Council in pursuance of sub-paragraph (2) of this paragraph or of any requirement mentioned in sub-paragraph (4) thereof, no notice need be given by them of any exercise of the powers conferred by this paragraph.
