122.Section 46(1) disapplies a provision of the Water Resources Act 1991 which otherwise would impose an absolute prohibition on abstracting water if this causes loss or damage to another person. Such a restriction could prevent or delay Crossrail works being constructed.
123.Section 46(2) provides that where water abstraction has caused loss or damage, the person suffering loss or damage must be compensated. The overall effect of section 46 is that the duty to avoid damage by water abstraction creates the possibility of compensation for damage but not the possibility of a court injunction. The practical protection for property owners arises from the requirement that the Environment Agency pre-approve abstraction, for which see Part 3 of Schedule 17.
