Water Management (General) Regulation 2025

The Minister may adopt a storage curve for a nominated approved work.

The approval holder must apply an adopted storage curve in the use of storage metering equipment.

If the approval holder for the work becomes aware of the adopted storage curve for the work being inaccurate by more than 5% of the volume of the work at a specified water level, the approval holder must, within 21 days of becoming aware of the inaccuracy—

notify the Minister, and

submit a revised storage curve for the work to the Minister.

The approval holder for the work may, at any other time, submit a revised storage curve for the work to the Minister.

A revised storage curve submitted under subsection (3) or (4) must be—

in the approved form, and

certified by a duly qualified person as meeting the relevant specifications set out in the storage curve standards approved by the Minister.

A revised storage curve submitted under subsection (3) or (4) is taken to be adopted by the Minister 72 hours after the revised storage curve is submitted unless the approval holder is given notice by the Minister that the revised storage curve will not be adopted.

A revised storage curve taken to be adopted under subsection (6) takes effect as the adopted storage curve for the work and a previously adopted storage curve for the work ceases to have effect.

The Minister must give notice of the adoption of a revised storage curve to the approval holder for the work.

If a revised storage curve is not adopted by the Minister, the existing adopted storage curve remains in force.
