Water Resources Act 1991

165 General powers to carry out flood defence and drainage works. E+W

(1) The Authority shall have power, in connection with a main river—

(a) to maintain existing works, that is to say, to cleanse, repair or otherwise maintain in a due state of efficiency any existing watercourse or any drainage work;

(b) to improve any existing works, that is to say, to deepen, widen, straighten or otherwise improve any existing watercourse or remove or alter mill dams, weirs or other obstructions to watercourses, or raise, widen or otherwise improve any existing drainage work;

(c) to construct new works, that is to say, to make any new watercourse or drainage work or erect any machinery or do any other act (other than an act referred to in paragraph (a) or (b) above) required for the drainage of any land.

(2) The Authority shall also have power, irrespective of whether the works are in connection with a main river, to maintain, improve or construct drainage works for the purpose of defence against sea water or tidal water; and that power shall be exercisable both above and below the low-water mark.

(3) The Authority may construct all such works and do all such things in the sea or in any estuary as may, in its opinion, be necessary to secure an adequate outfall for a main river.

(4) The Authority may by agreement with any person carry out, improve or maintain, at that person’s expense, any drainage works which that person is entitled to carry out, improve or maintain; but for the purposes of this subsection the expense to be borne by that person shall not include the amount of any grant paid under section 149(3) above in respect of the works in question.

(5) The Authority may enter into an agreement with any local authority or with any navigation authority for the carrying out by that authority, on such terms as to payment or otherwise as may be specified in the agreement, of any work in connection with a main river which the Authority is authorised to carry out.

(6) Nothing in subsections (1) to (3) above authorises any person to enter on the land of any person except for the purpose of maintaining existing works.

(7) In this section “watercourse” has the same meaning as in Part IV of this Act; and subsections (2) and (3) of section 113 above shall apply for the purposes of determining any question arising under this section as to—

(a) whether any work is a drainage work in connection with a main river; or

(b) whether any proposed work will, if constructed, be such a drainage work,

as they apply for the purposes of that Part.
