Section 19 of the Reservoirs Act 1975 provides that, where a civil engineer makes a report relating to a large raised reservoir and includes in that report recommendations as to measures to be taken in the interests of safety at the reservoir or as to the time when the reservoir should next be inspected, the undertakers may, if they wish to dispute any such recommendation, refer it to another engineer, called a “referee”, who will investigate their complaint.
