Paragraph 6
If, during the construction of a specified work or within 10 years after the completion of any such work and wholly or partly in consequence of its construction, there is caused or created an accumulation or erosion which causes damage, the Company shall, if so required by the Agency before or within the period of 10 years after such completion, remedy such accumulation or erosion, in the manner specified in sub-paragraph (4), and, if they refuse or fail so to do, the Agency may itself cause work to be done and may recover the reasonable cost thereof from the Company.
Should any accumulation or erosion, in consequence of such construction, arise within the said period of 10 years and be remedied in accordance with sub-paragraph (1), any recurrence of such accumulation or erosion shall from time to time be so remedied by the Company during the said period of 10 years and at any time thereafter, save that the Company’s obligation under this paragraph shall cease in the event that following the remedying of any accumulation or erosion a period of 10 years elapses without any further accumulation or erosion being caused or created in consequence of such construction.
In sub-paragraphs (1) and (2), “damage” means any damage to the bed or banks of the river or any adverse effect upon the structure or operation of any outfall, flood or sea defences or any jetty or other structure under the jurisdiction of the Agency for the purposes of the Water Resources Act 1991.
For the purposes of sub-paragraphs (1) and (2)—
in the case of an accumulation, the remedy shall be its removal or such other protective works or measures as may be reasonably required by the Agency; and
in the case of erosion, the remedy shall be the carrying out of such reconstruction works and other protective works or measures as may be reasonably required by the Agency,
any such protective works being subject to paragraph 13.
In the event that surveys, inspections, tests or sampling establish that such accumulation or erosion would have been caused in any event by factors other than the construction of a specified work the Company shall be liable to remedy such accumulation or erosion only to the extent that the same is attributable to such construction.
