(4) The undertaker shall 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 shall not be unreasonably withheld; and
(b)where that person has been given the opportunity to supervise the making of the opening.
(5) The undertaker 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.

(b)other expressions, except watercourse, used both in this article and in the Water Resources Act 1991 have the same meaning as in that Act.
20.—(1) Subject to the following provisions of this article, the undertaker may at its own expense carry out such protective works to any building lying within the Order limits as the undertaker considers to be necessary or expedient.
(2) Protective works may be carried out—
(a)at any time before or during the construction in the vicinity of the building of any part of the authorised works; or
(b)after the completion of the construction of that part of the authorised works in the vicinity of the building at any time up to the end of the period of 5 years beginning with the day on which that part of the authorised works is first opened for use.
(3) For the purpose of determining how the functions under this article are to be exercised the undertaker may enter and survey any building falling within paragraph (1) and any land within its curtilage.
(4) For the purpose of carrying out protective works under this article to a building the undertaker may (subject to paragraphs (5) and (6))—
(a)enter the building and any land within its curtilage; and
(b)where the works cannot be carried out reasonably conveniently without entering land which is adjacent to the building but outside its curtilage, enter the adjacent land (but not any building erected on it).
(5) Before exercising—
(a)a right under paragraph (1) to carry out protective works to a building;
(b)a right under paragraph (3) to enter a building and land within its curtilage;
(c)a right under paragraph (4)(a) to enter a building and land within its curtilage; or

the undertaker shall, except in the case of emergency, serve on the owners and occupiers of the building or land not less than 14 days' notice of its intention to exercise that right and, in a case falling within sub-paragraph (a) or (c), specifying the protective works proposed to be carried out.
(6) Where a notice is served under paragraph (5)(a), (c) or (d), the owner or occupier of the building or land concerned may, by serving a counter-notice within the period of 10 days beginning with the day on which the notice was served, require the question whether it is necessary or expedient to carry out the protective works or to enter the building or land to be referred to arbitration under article 52 (arbitration).
(7) The undertaker shall compensate the owners and occupiers of any building or land in relation to which the powers conferred by this article have been exercised for any loss or damage arising to them by reason of the exercise of those powers.
(8) Where—
(a)protective works are carried out under this article to a building; and
(b)within the period of 5 years beginning with the day on which the part of the authorised works constructed in the vicinity of the building is first opened for use it appears that the protective works are inadequate to protect the building against damage caused by the construction or operation of that part of the authorised works,
the undertaker shall compensate the owners and occupiers of the building for any loss or damage sustained by them.
(9) Without prejudice to article 51 (no double recovery) nothing in this article shall relieve the undertaker from any liability to pay compensation under section 10(2) of the 1965 Act.
(10) Any compensation payable under paragraph (7) or (8) shall be determined, in case of dispute, under Part 1 of the 1961 Act.

(4) No trial holes shall be made under this article—
(a)in a carriageway or footway without the consent of the highway authority; or

but such consent shall not be unreasonably withheld.
