“(1) Subject to the following provisions of this section, to section 162(9) below and to the provisions of Chapter III of this Part, every relevant undertaker shall, for the purpose of carrying out its functions, have power— (a) to lay a relevant pipe (whether above or below the surface) in any land which is not in, under or over a street and to keep that pipe there; (b) to inspect, maintain, adjust, repair or alter any relevant pipe which is in any such land; (c) to carry out any works requisite for, or incidental to, the purposes of any works falling within paragraph (a) or (b) above.”
“(1) Subject to the following provisions of this paragraph, a sewerage undertaker shall make full compensation to any person who has sustained damage by reason of the exercise by the undertaker, in relation to a matter as to which that person has not himself been in default, of any of its powers under the relevant sewerage provisions.”
“(1) If the value of any interest in any relevant land is depreciated by virtue of the exercise, by any relevant undertaker, of any power to carry out pipe-laying works on private land, the person entitled to that interest shall be entitled to compensation from the undertaker of an amount equal to the amount of the depreciation. (2) Where the person entitled to an interest in any relevant land sustains loss or damage which— (a) is attributable to the exercise by any relevant undertaker of any power to carry out pipe-laying works on private land; (b) does not consist in depreciation of the value of that interest; and (c) is loss or damage for which he would have been entitled to compensation by way of compensation for disturbance, if his interest in that land had been compulsorily acquired under section 155 of this Act, he shall be entitled to compensation from the undertaker in respect of that loss or damage, in addition to compensation under sub-paragraph (1) above. (3) Where any damage to, or injurious affection of, any land which is not relevant land is attributable to the exercise by any relevant undertaker, of any power to carry out pipe-laying works on private land, the undertaker shall pay compensation in respect of that damage or injurious affection to every person entitled to an interest in that land.”
“Section 10 of the Act of 1965, so far as material, provides: “(1) If any person claims compensation in respect of any land, or any interest in land, which has been … injuriously affected by the execution of the works … any dispute arising in relation to the compensation shall be referred to and determined by the Lands Tribunal. (2) This section shall be construed as affording in all cases a right to compensation for injurious affection to land which is the same as the right whichsection 68 of the Lands Clauses Consolidation Act 1845 has been construed as affording …”
“If any party shall be entitled to any compensation in respect of any lands, or of any interest therein, which shall have been … injuriously affected by the execution of the works” he shall follow the course therein directed. In Argyle Motors (Birkenhead) Ltd. v. Birkenhead Corporation [1975] A.C. 99 , 129 Lord Wilberforce described section 68 as having “over 100 years, received through a number of decisions, some in this House, and by no means easy to reconcile, an interpretation which fixes on it a meaning having little perceptible relation to the words used.”
“… I agree with Ward LJ that damage to the amenity of land caused by nuisances involving personal discomfort, having the effect of reducing the value of the land to let or sell, is damage to the land just as much as physical injury.”
