The Water Account, Australia (WAA) is an environmental-economic account produced by the Australian Bureau of Statistics (ABS), which is compiled, as far as possible, in accordance with the System of Environmental-Economic Accounting (SEEA) and the SEEA-Water frameworks. It includes water supply and use tables for both physical volumes and monetary values.
The following section outlines the broad concepts, sources, and methods for the Water Account.
The WAA was developed using the SEEA and the SEEA-Water frameworks. SEEA was first published by the United Nations in 1993 and was elevated to an international statistical standard in 2012. The SEEA framework extends the boundaries of the System of National Accounts (SNA) framework to include environmental resources, which occur outside the economic production boundaries that are measured by the SNA.
Water supply and use tables describe water flows from the environment to the economy, within the economy, and from the economy to the environment (SEEA-Water, 2012, S. 3.1). This includes:
The monetary supply and use tables present aggregates of monetary data (dollars) in terms of the supply and use of water within the Australian economy. Monetary supply and use tables illustrate the economic transactions associated with the use of distributed and reuse water and the provision of sewerage, drainage and wastewater services.
Key concepts are listed below:
Refers to the movement of water from the environment into the economy, either permanently or temporarily. SEEA identifies the environment as the supplier and the industry/household as the user (SEEA-Water, S 3.6). Extracted water can be further classified into three main sources:
Refers to water flows from one user (or supplier) to another user after extraction. This includes the supply and use of potable and non-potable water from one economic unit to another (SEEA-Water, 2012 S 3.31). In the WAA, distribution losses are recorded as water use by the industry supplying the water (usually the Water supply, sewerage and drainage services industry).
Water transferred/delivered from one water supplier/provider to another water supplier/provider. This distinction is required to ensure the same volume of water is not counted twice (in the physical supply and use tables) as the water moves through the economy; however, these exchanges are valued in the monetary tables.
Represents water that has been used by an economic unit or household, and then transferred between economic units. The industry collecting wastewater is a “user” in the physical supply and use tables, while in the monetary tables that industry is a “supplier” of sewerage and wastewater services (SEEA-Water S 3.9). The most commonly understood form of wastewater is sewage; however, non-sewage wastewater products are also included (SEEA-Water, 2012, S 3.12). Stormwater and drainage water are not currently included in the supply and use tables in the WSS, as much of this is simply redirected into nearby water systems. However, in Australia, there is some infiltration of stormwater into sewerage systems in many regions, so naturally some stormwater is included in the wastewater estimates.
Represents the transformation of wastewater into another economic product that is distributed throughout the economy (SEEA-Water, 2012, S 3.12). In the WAA this includes the transformation of stormwater and drainage water.
Represents the flows of water from industries and households to the environment. This excludes flows of water to wastewater treatment facilities but includes flows of water from treatment facilities directly to the environment. The SEEA records return flows as use by the environment (SEEA-Water, 2012, S 3.15).
Water consumption refers to the amount of water that is lost by the economy during use, in the sense that the water has entered the economy but has not returned to the environment. Water is instead incorporated into products, evaporated, transpired by plants or simply consumed by households or livestock. Water consumption is equal to the the difference between water use and water supply. The concept of water consumption used in SEEA-Water is consistent with the hydrological concept. It differs, however, from the concept of consumption that is used in the National Accounts, which instead refers to water use (SEEA-Water, 2012, S 3.44).
The WAA uses the Australian and New Zealand Standard Industrial Classification (ANZSIC) for its industry classification. The ANZSIC is implemented for all ABS industry-classified statistics and is a fundamentally important reference for organisations wishing to interpret these statistics or to compile their own statistics on a comparable basis.
In the monetary account, this refers to final consumption expenditure by households, or expenditure incurred by resident households on the consumption of water and related services (including sewerage services).
Social benefits paid in kind consist of goods and services provided to households by government and private, non-market producers (non-profit institutions serving households, or NPISHs), either free or at prices that are not economically significant (SNA, 2008, S 8.141).
Compulsory, unrequited payments, in cash or in kind, made by institutional units to government units (SNA, 2008, S 7.71).
Current unrequited payments that government units, including non-resident government units, make to enterprises on the basis of the levels of their production activities or quantities or values of the goods or services that they produce (SNA, 2008, S 7.98).
Exports of goods and services consist of sales, barter, or gifts or grants, of goods and services from residents to non-residents (SNA 1993, S 14.88).
Imports of goods and services consist of sales, barter, or gifts or grants, of goods and services from non-residents to residents (SNA 1993, S 14.88).
Description: the WSSS collection is an ABS census of all known water and wastewater suppliers/utilities across Australia. It collects physical and monetary data on water supply, water treatment, and return flows of water to the environment.
Frequency: annual, financial year.
Series used: 2014-15 to 2020-21 inclusive.
Geography: state/territory and national.
Key data used:
Water supply, sewerage and drainage services industry estimates for
The WSSS is used as a control total for use of distributed and reuse water by industries; it also sets the unit price for Agriculture water use.
Description: the EWES is an ABS survey conducted every three years, with the EIS conducted in the intervening two years. The EWES provides a more comprehensive range of data across industries, as well as providing benchmark estimates for selected data items. The EWES has a larger sample size than the EIS, therefore, some businesses/organisations selected for the EWES may not be selected for the EIS.
Frequency: triennial EWES and EIS with a financial year reference period.
Series used: 2014-15 and 2017-18 for EWES; 2015-16, 2016-17, 2018-19, 2019-20, and 2020-21 for EIS.
Geography: state/territory and national (EWES); national only (EIS).
Key data used:
Self-extracted use, distributed supply, reuse supply, and return flows data for the following industries:

Description: the REACS is run annually by the ABS in between the five-yearly Agricultural census. The scope of the REACS and Agricultural census collection is all businesses operating agricultural land in Australia who have an estimated value of agricultural operations (EVAO) of $40,000 or greater.
Frequency: REACS is run annually in the years between the five yearly Agricultural census. The last Agricultural census reference period was 2020-21.
Series used: 2014-15, 2016-17, 2017-18, 2018-19, and 2019-20, for REACS; 2015-16 and 2020-21 for Agricultural census.
Geography: state/territory and national
Key data used:
Note: the agricultural water use data presented in this publication is different to the data presented in the ABS publication Water Use on Australian Farms (WUOAF). This is because: (a) the multiple data sources used for the WAA compilation, compared to the single source of ABS survey data (REACS) used to produce WUOAF; (b) the WUOAF publication presents an ‘activity view’ of agriculture – therefore, its estimates of water use are slightly different to the ‘industry view’ estimates presented in the physical water supply and use tables in WAA; and (c) the scope of WUOAF is all businesses operating agricultural land in Australia who have an estimated value of agricultural operations (EVAO) of $40,000 or greater, while the WAA includes all agricultural businesses.
The Agriculture ‘industry' view presented in WAA includes only agricultural activity that occurs in businesses where the primary income-producing activity (i.e. the activity with value added that exceeds the value added of any other activity carried out by the same business) of the business is agricultural production.
Also note that losses from the distribution system for agriculture (e.g. evaporation and seepage from irrigation channels) are attributed to the Water supply industry rather than the Agriculture industry in WAA.

Key data used:
The methods used to compile the data in the WAA have been split into four broad groups that align with the data cubes published in this account:
All data items in the WSSDS industry highlights data cube were sourced directly from the WSSS collection with no notable methodological adjustments.
The general methods used to compile the physical supply and use tables of the water account are relatively straightforward. Data from the WSSS collection operates as a stabilising component, acting as a spine for the compilation. The basic premise behind this decision is that the WSSS collection is a relatively complete census of all water providers – a population who, by necessity, understand the subject matter. The EWES/EIS surveys are utilised to inform industry splits, excluding Agriculture, and provide detail that is lacking in the WSSS collection instrument. The Agricultural census and surveys (REACS) fill a similar niche for Agriculture.
With this in mind the following represents a broad outline of how the data feeds into each supply and use water category.
Self-extracted water: the sum of all self-extracted water use sets the supply figure for the environment to the economy.
Distributed and reuse water: derived from the WSSS collection, the vast majority of water is supplied by the Water supply, sewerage and drainage services industry. EWES water supply estimates set total supply for water providers outside of the Water supply, sewerage and drainage services industry, while total use by industry is used to allocate these data to states/territories.
Wastewater: currently the WAA does not include estimates for the supply of wastewater to sewerage systems, split by individual industries and households. This is a known data gap that will be explored in future iterations of the WAA. In the interim, the total wastewater supplied is estimated in the account. The total wastewater supply is aligned to the total wastewater received by subdivision 28, sourced from the WSSS collection.
Return flows: formerly referred to as "regulated discharges" in the WAA, return flows estimates are sourced from the WSSS collection (state/territory and national) and EWES (national) surveys, however no data is currently available for return flows from Agriculture and households. These are known data gaps that will be explored in future iterations of the WAA. Total use by the Waste collection, treatment and disposal services industry is used to allocate EWES national estimates to state/territory estimates. Mining and Manufacturing utilise total self-extracted water in the same way. For the Electricity and gas industry, return flows estimates were aligned with self-extracted surface water.
Self-extracted water: WSSS, EWES, EIS, and REACS all collect data on self-extracted water use – these data are utilised directly.
Distributed and reuse water: WSSS and EWES/EIS supply estimates set the total. WSSS sets control totals for ANZSIC divisions A, B, C, and D and is distributed based on subdivision ratios produced from the EWES/EIS and ANZSIC 3-digit division estimates from the REACS and the Agricultural census. EWES Supply and the residual WSSS supply is allocated to other industries. Use by the Water supply, sewerage and drainage services industry is sourced from the WSSS and includes water losses in distribution.
Wastewater: all wastewater use is currently assigned to the Water supply, sewerage and drainage services industry, and collected is via the WSSS collection. While some other industries are likely treating a small amount of wastewater this would not involve wastewater transferring between institutional units and is therefore out of scope.
Return flows: represent flows from the economy to the environment; under SEEA conventions (SEEA Water S 3.16) all return flows are attributed to the environment. Data collected via the WSSS, EWES and EIS.
Note: environmental flows are out of scope in this edition of the WAA. Environmental flows relate to (a) statutory requirements to maintain specific water regimes or (b) specific entitlements, which accrue annual allocations of water that can be extracted (or left in-stream) for environmental purposes.
The monetary water supply and use tables are displayed in purchasers’ and current prices. They generally follow the same format as the physical supply and use tables, however there are a number of key differences, as outlined below:
Self-extracted water: self-extracted water supply is currently not valued in the account.
Distributed water: revenue estimates for the Water supply, sewerage and drainage services industry are the sum of retail revenue received for distributed (potable and non-potable) water. Estimates for industries other than Water supply and sewerage services industry utilise household and industry derived unit values (prices) and the physical volume of distributed water supplied by these industries from the physical supply and use tables.
Reuse water: revenue estimates for the Water supply, sewerage and drainage services industry are the sum of retail revenue received for reuse water. Estimates for industries other than the Water supply, sewerage and drainage services industry utilise industry and household derived unit values (prices) and the physical volume of reuse water supplied by these industries from the physical and supply and use tables.
Bulk water, distributed: supply is the sum of the associated revenue from the WSSS collection. All revenue is allocated to the Water supply, sewerage and drainage services industry.
Bulk water, reuse: supply is the sum of the associated revenue from the WSSS collection. All revenue is allocated to the Water supply, sewerage and drainage services industry.
Sewerage wastewater: supply is set by total revenue received from sewerage charges and trade waste charges, as reported in the WSSS collection.
Return flows: currently not valued in the account.
Self-extracted water: currently not valued in the account.
Distributed water use for the Mining, Manufacturing, Electricity, Gas and Waste services industries are derived by multiplying the price of water paid by the physical use. The price is derived from data collected on the Energy, water and environment survey (EWES) and Environmental indicators surveys (EIS), by dividing expenditure on water by the volume of water used.
Agricultural distributed water expenditure was calculated using data from the WSSS collection. An agricultural unit price was derived by dividing total revenue received for distributed water by the total volume of distributed water, at a state/territory level, for irrigation units. These unit prices were multiplied by the agricultural use of distributed water estimates from the physical supply and use tables
Household estimates are derived by multiplying a unit price by physical use. The unit price is calculated using the Bureau of Meteorology’s National Performance Reports (NPR) data via the following methodology:
Reuse water: reuse water follows the same methodology as distributed water use.
Bulk water, distributed: expenditure on distributed bulk water mirrors the supply revenue values.
Bulk water, reuse: expenditure on reuse bulk water mirrors the supply revenue values.
Sewerage and drainage services: EWES and EIS provide estimates for the Mining, Manufacturing, Electricity, Gas and Waste services industries. For Agriculture and Other industries (ANZSIC Divisions E-S), estimates were available in the 2014-15 EWES and modelled forward using a Gross Value Added index by industry by state/territory. The gap between total supply and total industry use is allocated as household use.
Distributed water: total supply is used as the control total, with differences between supply and use allocated to use by Other industries (ANZSIC divisions E-S).
Reuse water: total supply is used as the control total. A weighted balancing approach was used to address discrepancies between the supply control total and use total, with the difference allocated between industries/households in the same proportions as reuse water use before balancing.
Bulk water, distributed: no balancing required.
Bulk water, reuse: no balancing required.
Sewerage and drainage services: total supply less total industry use is allocated to households' water use.
The summary tables aim to highlight key indicators of the WAA in a time series, and provide other relevant information linked with data from the supply and use tables. These indicators aim to enhance the ability of users to rapidly synthesise key stories. The data items presented in these tables, and not represented in the supply and use methodology described above, are described below:
The Gross Value of Irrigated Agricultural Production (GVIAP) is presented for Australia, States and Territories, Natural Resource Management (NRM) regions, and the Murray-Darling Basin region for key agricultural commodity groups.
GVIAP refers to the gross value of agricultural commodities that are produced with the assistance of irrigation. The gross value of commodities produced is the value placed on recorded production at the wholesale prices realised in the marketplace. This definition of GVIAP does not refer to the value that irrigation adds to production i.e. the 'net effect' that irrigation has on production. GVIAP is not a measure of productivity, so extreme care must be taken if attempting to use GVIAP to compare different commodities. Rather, it is a more effective tool for measuring changes over time or comparing regional differences in agricultural production.
The scope of GVIAP is all agricultural businesses with an estimated value of agricultural operations (EVAO) of $40,000 or greater, identified through the Rural environment and agricultural commodities survey (REACS) noted in the sources section. In 2014-15 businesses with an EVAO of $5,000 or greater were included. For more information about EVAO, refer to the Explanatory Notes contained in the publication Agricultural Commodities, Australia.
Pricing data is obtained from the Value of agricultural commodities produced (VACP) survey noted in the sources section of this document.
GVIAP is calculated for each irrigated 'commodity group' produced by agricultural businesses. That is, GVIAP is generally not calculated for individual commodities, but for groups of 'like' commodities according to irrigated commodity groupings on the agricultural censuses and survey forms. The irrigated commodity groups vary slightly on the survey form from year-to-year, so changes can occur in the published items.
The agricultural censuses and surveys collect area and production data for a wide range of individual commodities.
The statistics presented calculate GVIAP at the unit (farm) level, using three simple rules:
Approximately 90% of cases follow rules 1 or 3; that is, the commodity group on a particular farm is either 100% irrigated or not irrigated at all.
In this publication 'yield' is defined as the production of the commodity per area grown.
The yield formula is explained in full in: Information Paper: Methods of estimating the Gross Value of Irrigated Agricultural Production.
Outlined here is the formula utilised:
\(GVIAP=A_iY_iP\)
Where
\(Y_i= \frac{Q}{\frac{A_d}{Y_{diff}+A_i}}\)
Hence
\(GVIAP=A_i\times \frac{Q}{\frac{A_d}{Y_{diff}+A_i}}\times P\)
Where
\(A_i= \) area of the commodity under irrigation (ha)
\(Y_i=\) estimated irrigated yield for the commodity (t/ha or kg/ha)
\(P=\) unit price of production for the commodity ($/t or $/kg)
\(Q=\) total quantity of the commodity produced (t or kg)
\(A_d= \)area of the commodity that is not irrigated (ha)
\(Y_{diff}=\) yield difference factor
Yield difference factors are the estimated ratio of irrigated to non-irrigated yield for a given commodity group. They are calculated for a particular commodity group by taking the yield (production per hectare) of all farms that fully irrigated the commodity group and dividing this 'irrigated' yield by the yield of all farms that did not irrigate the commodity group. Further information on yield difference factor methodology can be found here: Information Paper: Methods of estimating the Gross Value of Irrigated Agricultural Production.
The GVIAP for the following commodities has been calculated using the yield formula, with varying yield differences:
Note: a yield difference of 1 implies no difference in yield between irrigated and non-irrigated production.
Not all agricultural commodity groups can be satisfactorily calculated using the yield formula, in particular dairy production - It is assumed that if there is any irrigation of grazing land on a farm that is involved in any dairy production, then all dairy production on that farm is classified as irrigated.
For Meat cattle, sheep and other livestock the model was as follows:
Most of the irrigated commodity groups included in these tables are irrigated by the application of water directly on to the commodity itself, or the soil in which it is grown. The exception relates to livestock, which includes dairy. For example, the GVIAP of 'dairy' simply refers to all dairy production (i.e. milk) from dairy cattle that grazed on irrigated pastures or crops. Estimates of GVIAP for dairy production must be used with caution, because in this case the irrigation is not applied directly to the commodity, rather it is applied to a pasture or crop which is then eaten by the animal from which the commodity is derived (milk). Therefore, for dairy production, the true net contribution of irrigation (i.e. the value added by irrigation, or the difference between irrigated and non-irrigated production) will be much lower than the total irrigation-assisted production (the GVIAP estimate).
The difference between (a) the net contribution of irrigation to production and (b) the GVIAP estimate is probably greater for livestock grazing on irrigated crops/pastures than for commodity groups where irrigation is applied directly to the crops or pastures.
Similarly, estimates of GVIAP for all other livestock (meat cattle, sheep and other livestock) must be treated with caution, because as for dairy production, the issues around irrigation not being directly applied to the commodity also apply to these commodity groups.
The Australian and New Zealand Standard Industrial Classification (ANZSIC) is the standard of classification used in Australia and New Zealand for the collection, compilation, and publication of statistics by industry.
A geologic formation which is capable of holding water and through which water can percolate. Aquifers are capable of yielding quantities of groundwater for economic activities.
Water supplied by a water provider/supplier/utility to another water provider/supplier/utility. Also known as "wholesale" water (as opposed to "retail" water).
The area of land determined by topographic features, within which rainfall will contribute to run-off at a particular point. The catchment for a major river and its tributaries is usually referred to as a river basin.
Estimates are valued at the prices of the period to which the observation relates. For example, estimates for 2017-18 are valued using 2017-18 prices. This contrasts to chain volume measures where the prices used in valuation refer to the prices of the previous year.
Annually-reweighted chain Laspeyres volume indexes referenced to the current price values in a chosen reference year (i.e. the year when the quarterly chain volume measures sum to the current price annual values). Chain Laspeyres volume measures are compiled by linking together (compounding) movements in volumes, calculated using the average prices of the previous financial year, and applying the compounded movements to the current price estimates of the reference year.
Water supplied to a user including through a natural (e.g. river) or non-natural network (e.g. piped or open channel), and where an economic transaction has occurred for the exchange of this water. The majority of distributed water is supplied by the Water supply, sewerage and drainage services industry (ANZSIC Division 28). The water supply component consists of units mainly engaged in storage, purification or distribution of water by pipeline or carrier. It may also include the operation of irrigation systems that supply water to a farm and the supply of steam and hot water. Distributed water can include potable, mains and raw water but does not include reuse or bulk water.
Exports of goods and services consist of sales, barter, or gifts or grants, of goods and services from residents to non-residents.
One thousand million litres, or 1,000,000,000 litres. 1 Gigalitre = 1,000,000 cubic metres.
The gross value of commodities produced. It is the value placed on recorded production at the wholesale prices realised in the market place.
Water supplied to other water providers and customers, plus losses, own use by water providers and environmental flows.
Water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
The value of an industry's output at basic prices, minus the value of goods and services consumed as inputs during the process of production. Basic prices valuation of output removes the distortion caused by variations in commodity taxes and subsidies across the output of individual industries.
Imports of goods and services consist of sales, barter, or gifts or grants, of goods and services from non-residents to residents.
Water artificially applied to soils (i.e. does not include precipitation/rainfall).
One thousand litres (1,000 litres). 1 kilolitre = 1 cubic metre.
One million litres (1,000,000 litres). 1 megalitre = 1,000 cubic metres.
In the physical water supply and use tables, "Other industries" refers to the following list of industries, according to the Australian and New Zealand Standard Industrial Classification (ANZSIC):
An organisation that supplies water but whose main activity is in an industry other than the Water supply, sewerage and drainage services industry (e.g. Mining or Manufacturing).
Water that is suitable for human consumption (e.g. drinking water).
The amount paid by the purchaser, excluding any tax deductible by the purchaser, in order to take delivery of a unit of a good or service at the time and place required by the purchaser. The purchaser’s price of a good includes any transport charges paid separately by the purchaser to take delivery at the required time and place.
Water extracted from the environment that has not been treated.
Potable or non-potable water supplied by a water supplier to customers not classified as water suppliers.
Return flows represent the flows of water from industries and households to the environment. This excludes flows of water from industries and households to wastewater treatment facilities but includes flows of water from treatment facilities directly to the environment. The SEEA records this as use by the environment.
Wastewater (including sewage) that is collected, on-supplied and used again by other businesses/households. It may have been treated to some extent. Reuse water is also known as recycled water or effluent re-use.
Revenue from 'pay for use' and base rate charges (i.e. volumetric and fixed rates) for the provision of wastewater. It also includes revenue generated from trade waste charges.
Revenue from the provision of water supply services to residential and non-residential properties. Also includes revenue generated from bulk supply or bulk sale of potable and non-potable/raw water, treated wastewater or reuse water and desalinated water.
A process where salt is removed from water with a high salt content (usually seawater but sometimes other brackish water) to make it suitable for domestic or industrial use.
Water extracted directly from the environment for use (including surface water, groundwater and other bodies) for the purpose of supplying to others (including other water suppliers) and/or for own use. It also includes water produced from salt water desalination.
Infrastructure (e.g. pipe and drains) used to remove sewage (wastewater).
Social transfers in kind consist of good and services provided to households by government and private, non-market producers free or at prices that are not economically significant.
Current unrequited payments that government units, including non-resident government units, make to enterprises based on the levels of their production activities or quantities or values of the goods or services that they produce.
Physical water supply and use tables which provide information on the volumes of water extracted, supplied within the economy and discharged back into the environment by economic activity and households.
Water on the surface of continents such as in a river, lake, wetland, ice or snow. This excludes sea water.
A framework used to develop environmental accounts by integrating environmental information into an accounting framework. The primary manual is the SEEA Central Framework (SEEA-CF) which provides the conceptual basis for describing the interrelationship between the natural environment and the economy.
An elaboration of the SEEA framework which provides a conceptual framework for organising hydrological and economic information in a coherent and consistent framework. It is consistent with SEEA-CF.
An international framework which can be used to develop a comprehensive, consistent and flexible set of macro-economic accounts. The latest edition is the 2008 SNA.
Compulsory, unrequited payments, in cash or in kind, made by institutional units to government units.
Any water that has been used by an economic unit or household, and then transferred between economic units, usually for treatment. The most commonly understood form of wastewater is sewage; however, non-sewage wastewater products are also included (for example, untreated effluent and trade waste).
The concept of water consumption provides an indication of the amount of water that is lost by the economy during use, in the sense that the water has entered the economy but has not returned to the environment directly. Water is instead incorporated into products, evaporated, transpired by plants or simply consumed by households or livestock. The difference between water use and water supply is referred to as water consumption. The concept of water consumption that is used in SEEA-Water is consistent with the hydrological concept. It differs, however, from the concept of consumption that is used in the national accounts, which instead refers to water use.
Water intensity is referred to as the ratio of physical flow to an economic aggregate (for example, ML/$m GVA) while water productivity represents the ratio of economic aggregate to physical flow (for example, $m GVA/ML). Water intensity is the inverse of water productivity.
Water that enters the water distribution system of a water provider but does not reach the end users/customers. Water losses can be attributed to seepage, leakage, evaporation (excluding evaporation from water storages), meter inaccuracies and theft.
A business or organisation that provides a reticulated water supply, irrigation water, reuse/recycle water and/or bulk water supply service. Water providers may be government or private and often operate water storage, purification and supply services. They may also provide sewerage or drainage services. Commonly referred to as a water utility or water supplier.
The provision of reticulated water supply (including desalinated water), irrigation water, recycled (reuse) water, bulk and/or retail water supply service.
Distributed water use plus self-extracted water use plus reuse water use. Note that this definition differs to the Water consumption definition in that it is a gross measure, rather than netting out the volumes of water in return flows, wastewater supply or water supplied to other users.
