Water Management Act 2000

An authorised person may enter premises at a reasonable time for the purpose of taking the remedial measures for which the authorised person is appointed.

For the purpose of entering or leaving premises, an authorised person may enter other premises.

A power to enter premises conferred by this section authorises entry by any reasonable means.

An authorised person may, while on premises under this section, take action reasonably necessary to take the remedial measures, including—

interfering with land or anything on the land, and

interfering with a water supply work.

An authorised person must, if asked by the owner or occupier of premises, produce a copy of the authorised person’s instrument of appointment.

This section does not authorise an authorised person to enter premises used solely for residential purposes except with the consent of the occupier of the premises.
