Paragraph 23

Subject to paragraphs 24 and 25 and paragraph 22(5)(b), if by reason of the construction of any specified work or of the failure of any such work the efficiency of any drainage work for flood defence purposes or land drainage is impaired, or that drainage work is otherwise damaged, the impairment or damage must be made good by the undertaker as soon as reasonably practicable to the reasonable satisfaction of the drainage authority and, if the undertaker fails to do so, the drainage authority may make good the impairment or damage and recover from the undertaker the expense reasonably and properly incurred by it in doing so.
