LT 6 March 1990. Reference by consent to the LT on the compensation payable by the water authority (T) to the claimants (S) for damage, or injurious affection to land belonging to S in Oxfordshire caused by construction of a water main . The claim was made under section 19 and sched 3 to the Water Act 1945 as amended and was for £17,549 based on 50% of a land value with vacant possession of £2,200 per acre; a 20m width of working; and a price per yard run of £3.30. T contended for a similar formula based on a width of 22 yards; an open market value of £2,000 discounted by 60%. This gave a figure of £7,251 based on £1.37 per yard. LT held that the damage or injurious affection attributable to the pipe affects not merely the strip but each farm as a whole; the reversion s to the agricultural tenancies are diminished in value. The provisions of the Land Compensation Act 1961 do not apply; instead regard must be had to the value of the land to the owner. The valuation of £2,200 per acre
