1.5.1.2 Groundwater


This section summarises groundwater account data in the Namoi subregion for the available water years (year starting in July and ending in June) for the period 2006–07 to 2013–14. Several groundwater sources in the Namoi subregion have data for only a subset of this period, and in those cases the shorter record has been used.

Groundwater in the Namoi subregion is managed as 21 groundwater sources. The groundwater sources represent geological sequences that are hydrogeologically similar and grouped together for management purposes, groundwater management is discussed further in Section 1.5.1.2.2. Figure 7 shows the groundwater sources present across the Namoi subregion. It is important to note that several of the groundwater sources extend beyond the limits of the subregion (Figure 7 indicates the proportion of each groundwater source that lies within the Namoi subregion). However, water accounting information is generally only available for groundwater sources in their entirety and all of the water account data presented in this product relates to the whole of each groundwater source, not the proportion that lies within the subregion.

1.5.1.2.1 Current water accounts

Groundwater inflows

Recharge from rainfall is the only inflow used for the groundwater sources when setting the sustainable diversion limits (calculated by the Murray–Darling Basin Authority for sustainable diversion limit (SDL) resource units) or long-term average extraction limits (LTAEL) (set by the NSW Office of Water) across the Namoi subregion. Table 7 and Table 8 present the recharge volumes used to determine LTAEL for each groundwater source, as set in the water sharing plans (NSW Government 2003; 2008; 2011a; 2011b; 2011c; 2012).

aRecharge estimates were taken from the relevant water sharing plans or water sharing plan background documents.

bThis value is not recharge. Rather, it is the volume of water required to maintain pressure levels experienced under the level of water extraction associated with the water entitlements, infrastructure and management rules in place at 1990.

cRecharge estimates were not available for these groundwater sources, as recharge was not used to determine the SDL/LTAEL. Estimated annual licensed extraction and estimated stock and domestic use, at the commencement of the plan, were used instead.

dStock and domestic usage estimates for each groundwater source were taken from the relevant water sharing plans.

eSDL values were taken from Schedule 4 of the Commonwealth’s Basin Plan 2012.

fLTAEL values for the Surat and Southern recharge groundwater systems are drawn from the relevant water sharing plans, as they are not considered part of the MDB.

gThe LTAEL for the these groundwater sources are obtained from NSW’s Water Sharing Plan for the Namoi Unregulated and Alluvial Water Sources 2012 as they are grouped together as part of a single groundwater SDL resource unit in the Commonwealth’s Basin Plan 2012.

hThe long-term SDL for the Upper Namoi is only available for the region as a whole, and not for each of the zones.

Data: NSW Office of Water (Dataset 2); Burrell et al (2014); NSW Government (2003); NSW Department of Water and Energy (2009); NSW Office of Water (2011; 2012a; 2012b; 2013)

The NSW Office of Water uses groundwater planning models for the Upper and Lower Namoi alluvial systems to produce detailed annual water budgets. The water budget presents modelled values for a range of inflows and outflows to the alluvial groundwater systems. It includes volumes of water that flow between the river and groundwater system, the lateral flow into and out of each layer, the flow between layers, recharge from rainfall and volumes of groundwater pumped from the model layers. This enables a change in water storage to be calculated for each layer. It is noted that modelled water budgets are only available for the Upper and Lower Namoi alluvial groundwater sources in the Namoi subregion.

Where planning models have not been developed, and there is insufficient monitoring bore data to estimate a complete budget, there is no information available regarding other (non-rain or groundwater extraction) elements of the water budget (e.g. flows between groundwater sources, changes to aquifer storage or flows to, or from, rivers). This is generally the case for the non-alluvial groundwater sources in the Namoi subregion. In these cases, the NSW Office of Water’s soil water budget accounting method is applied to obtain an estimate of the potential annual recharge. This method is used to determine deviations in annual potential recharge as a deviation from the long-term mean potential recharge. To date, this data layer has only been presented for the 2011–12 and 2012–13 water years (Burrell et al., 2014).

aA small proportion of the area of these zones lies outside the Namoi subregion, however, the exact proportion outside the subregion has not been quantified.

Groundwater outflows

Data on groundwater outflows are limited to data on extractions for consumptive use. Water licence data for the Namoi subregion were obtained from the NSW Office of Water (Dataset 2 and Dataset 3).

Figure 8 shows the distribution of licensed groundwater bores, and their associated water use category, simplified from the NSW Office of Water (Dataset 2). Table 9 shows the number of groundwater bores in these categories. There are approximately 10,300 licensed bores across the Namoi subregion. Most bores are licensed for stock and domestic use.

Groundwater extraction by coal mines and coal seam gas developments, both for use and for dewatering purposes, will occur from a number of groundwater sources and must be licenced. Further analysis and modelling of water use by mines and CSG developments will be presented in companion products 2.1, 2.3, 2.5 and 2.6.

An estimate of current groundwater usage

The groundwater use data presented in this product has been obtained from the NSW Water Register (NSW Office of Water, Dataset 2).

Groundwater use data comes from metering in some groundwater sources, however metering of groundwater extraction is not yet mandatory across all groundwater sources, and will be rolled out over time across NSW (NSW Office of Water, 2012b). All licensed bores in the Upper Namoi water sources (approximately 1100 bores) are metered and their usage is recorded at regular intervals (two to six readings per year) (Barrett, 2010). In contrast, basic water right volumes are estimated, as licencing and metering is not required for stock and domestic rights.

Table 10 presents the available time series usage data for all of the groundwater sources in the Namoi subregion. In summary, most of the groundwater used within the subregion is taken from five sources:

  • Lower Namoi – average annual use 75,510 ML/year, licensed volume 106,752 ML in 2013–14
  • Upper Namoi Zone 4 – average annual use 21,091 ML/year, licensed volume 39,303 ML in 2013–14
  • Upper Namoi Zone 5 – average annual use 15,906 ML/year, licensed volume 18,704 ML in 2013–14
  • Upper Namoi Zone 3 – average annual use 14,957 ML/year, licensed volume 25,364 ML in 2013–14
  • Upper Namoi Zone 8 – average annual use 12,923 ML/year, licensed volume 21,070 ML in 2013–14.

Table 10 Annual groundwater usage data for all groundwater sources in the Namoi subregion (excludes stock and domestic usage estimates)

These data relate to the entirety of each groundwater source, even where only a proportion of the area of the groundwater source lies within the Namoi subregion.

Data: NSW Office of Water (Dataset 2)

Figure 9 to Figure 13 show time series data for the numbers of licences within each licence class, and the licensed volume, allocation, and water use for each of the five groundwater sources listed above. The plots show that usage is consistently different to (and typically below) the licensed and allocated volumes. The groundwater access licences in the Namoi correspond to one of the following categories:

  • Aquifer access licences
  • Supplementary Water access licences
  • Aquifer (Town Water Supply) access licences
  • Local Water Utility access licences.

It should be noted that the available water determinations for Supplementary Water access licence class water in the Upper and Lower Namoi alluvial groundwater sources are being reduced incrementally in the water sharing plan, and will be reduced to zero ML per unit of share component at the start of the 2015–16 water year. This trend can be seen in the allocated water plots in Figure 9 to Figure 13. It can also be seen that the annual use exceeds the total allocation and licensed volume for 2013–14 in the Lower Namoi and Upper Namoi zones 3 and eight groundwater sources, and in 2012–13 and 2013–14 for the Upper Namoi zone 5. This has occurred due to licence holders making use of the carryover provisions available in these groundwater sources. Carryover provisions allow licence holders to accrue unused water allocation in their aquifer access licence accounts, and use up to two times their entitlement volume in any water year if the average of the preceding three year’s extraction does not exceed the extraction limit by 5% or greater, and providing the water is available in their water account.

The total licensed groundwater extraction volume in the Namoi subregion in 2013–14 was 327 GL/year. Extraction under Aquifer class access licences was 252.5 GL/year (77%), 57.7 GL/year (18%) under Supplementary Water class licences, 16.8 GL/year (5%) under Local Water Utility class licences and 0.025 GL/year (0.008%) under Aquifer (Town Water Supply) class licences. The mean annual groundwater usage from 2006–07 to 2013–14 was 165 GL/year.

1.5.1.2.2 Water management

Groundwater management across the Namoi subregion is undertaken through six water sharing plans prepared by the NSW government. The plans lie wholly or partially within the subregion: Figure 14 shows the extent and overlap of the areas governed by each water sharing plan. The plans cover the 22 groundwater sources defined by the NSW government in accordance with the Commonwealth’s Basin Plan 2012 (the Basin Plan), noting that two of the groundwater sources (the Surat and Southern Recharge) are not considered to be part of the Murray–Darling Basin (MDB).

Figure 14

Figure 14 Map showing the areas of each of the six water sharing plans in effect across the Namoi subregion

The eastern edge of the subregion lies along the eastern boundary of the Water Sharing Plan for the NSW Murray–Darling Basin Porous Rock Groundwater Sources, indicated F. Inset maps indicate the extent of each of the water sharing plans, as indicated by the letters A to F. Areas marked with multiple letters indicate areas where more than one water sharing plan is in effect, covering groundwater in different geological formations.

Source: Figure 31 in Burrell et al. (2014). This figure is not covered by a Creative Commons licence. It has been reproduced with the permission of the NSW Department of Trade & Investment.

Table 11 and Table 12 link the water sharing plans, MDB water resource plan areas and MDB SDL areas that relate to each of the groundwater sources that are part of the MDB.

Sustainable diversion limits have been set for all of the groundwater sources in the Namoi subregion that lie within the MDB. The groundwater sources that are considered part of the Great Artesian Basin (Surat and Southern Recharge) are outside the MDB, and have long-term average extraction limits set within the relevant water sharing plans.

The water sharing plans establish rules for sharing water between the environmental needs of the aquifer and water users, and also between different types of water use such as town supply, rural domestic supply, stock watering, industry and irrigation (NSW Office of Water, 2015a). All groundwater sources in the Namoi subregion are covered by commenced water sharing plans. Water sharing rules set out in the plan address issues such as allocating water to the environment (environmental water), trading water between and within groundwater sources, and for using ‘carryover’ provisions to delay access to allocated water from one year to the next.

NSW requires that all bores have a work approval and are registered, regardless of the intended purpose. A water use approval, with associated water access licences, is also required to use water for all purposes except basic landholder rights (for example, for stock and domestic purposes).

A water access licence entitles the licence holder:

  • to specified shares in the available water within a particular water management area
  • to take water at specified times, rates or circumstances from specified areas or locations.

Bores licensed for extraction for commercial purposes generally require a meter to be installed and have an annual extraction limit (NSW Office of Water, 2015b).

1.5.1.2.3 Gaps


There are several areas where additional monitoring or investigation would provide data that would help to improve the accuracy of the water accounting for each groundwater source, and consequently knowledge of the water budget elements for the water sources, including:

  • updating estimates for basic rights (stock and domestic) water consumption to reflect current usage patterns and utilise best available estimation techniques
  • investigating recharge to improve the accuracy of recharge estimates, for example the spatial variability of recharge
  • investigating barriers and connections between adjacent groundwater sources
  • undertake field monitoring to investigate individual elements of the modelled water balances to ensure all estimates of elements are realistic, for example measuring mine water inflows
  • including surface water – groundwater interactions in water accounting.
