NATURAL RESOURCES MANAGEMENT ACT 2004
Section 106
Notice of Assessment of Quantity of Water Taken when
Meter Readings are Not Used

I, IAN HUNTER, Minister for Sustainability, Environment and Conservation, hereby declare pursuant to Section 106 (3) of the Natural Resources Management Act 2004 (the Act) that, if meter readings are not used, the quantity of water taken during the 2017–2018 water use year will be determined on the basis and the method set out in Schedule 1.

Schedule 1

Basis

    1. For the purpose of Section 106 (1) (c) of the Act, the quantity of water taken will be assessed:

       (a)   on the basis of crop area;

       (b)   if the Minister is satisfied that crop area is not a reasonable basis to determine the quantity of water taken, on the basis of pump capacity;

       (c)   if the Minister is satisfied that pump capacity is not a reasonable basis to determine the quantity of water taken, on the basis of historical usage;

       (d)   if the Minister is satisfied that historical usage is not a reasonable basis to determine the quantity of water taken, on the basis of usage data; or

       (e)   if the Minister is satisfied that usage data is not a reasonable basis to determine the quantity of water taken, on the basis of the water allocation.

    2. Where the Minister has granted an exemption from the requirement to install a meter on a water source, the quantity of water taken will be assessed on the basis of the water allocation.

Method

    3. The method that will be used in assessing the quantity of water on the basis of crop area will be as follows:

       The estimation of water requirements for crops will be based on the methodology in Crop Evaporation—Guidelines for Computing Crop Water Requirements—Food and Agriculture Organisation of the United Nations Irrigation and Drainage Paper 56 (Allen, Pereira et al, 1998, ISBN No 92-5-104219-5). Local data (including rainfall and evaporation data) will be used in the estimation of the quantity of water taken. Water usage to account for irrigation system efficiency and for specific crop production process will be added where appropriate.

    4. The method that will be used in assessing the quantity of water on the basis of pump capacity will be as follows:

       Details of the duration of pumping and the normal operating capacity of the pump used to take water will be used to determine the quantity of water taken. The duration of pumping will be multiplied by the normal operating capacity of the pump.

       The maximum capacity of the pump will be used if the Minister is satisfied that the normal operating capacity of the pump is not a reasonable basis to determine the quantity of water taken.

    5. The method that will be used in assessing the quantity of water on the basis of historical usage will be as follows:

       The average of metered usage over the preceding two water use years, providing that the Minister is satisfied that the water was being used during that period for a similar purpose and in a similar manner, and is a reliable estimate of the quantity of water taken.

    6. The method that will be used in assessing the quantity of water on the basis of usage data will be as follows:

       Details of the usage data (including system operating times and flow rates, and/or the number of transfer tanks or dams filled used to take water) from the infrastructure used.

    This notice has effect in relation to the financial year commencing on 1 July 2017.

Dated 15 June 2017.

Ian Hunter, Minister for Sustainability,
Environment and Conservation
