Water restrictions in Australia explained

Water restrictions have been enacted in many cities and regions in Australia, which is the Earth's driest inhabited continent,[1] in response to chronic water shortages resulting from the widespread drought. Depending upon the location, these can include restrictions on watering lawns, using sprinkler systems, washing vehicles, hosing pavement, refilling swimming pools, etc. Overpopulation, evidence of drying climates, coupled with corresponding reductions in the supply of drinking water has led various state governments to consider alternative water sources to supplement existing sources, and to implement "water inspectors" who can issue penalties to those who waste water. Many states describe the different levels of water restrictions in terms of "stages": starting at Stage 1, for the least restrictive, going up as far as Stage 8. The highest level reached in the current drought has been stage 7 for Kingaroy. There are different definitions given to each "stage" in different states.

Water restrictions by state or territory

Australian Capital Territory

There are presently four stages of temporary water restrictions which can be imposed by ACTEW Corporation:[2]

Stage 1 Stage 2 Stage 3 Stage 4
Sprinklers and irrigation:Any day, after 6pm & before 9amDrippers only, 7–10am & 7–10pmNo reticulation
Hand-watering gardens and lawns:No restrictionsAlternate days, 7–10am & 7–10pmNo watering lawns; watering plants alternate days, 7–10am & 7–10pmGreywater only
Swimming pools:No emptying or filling; Topping-up allowedNo topping-up, emptying or filling
Car washing:Once a week, or at commercial car washOnce a month, or at commercial car washOnly at commercial car washesNo car washing
Window cleaning:Only with bucket or high-pressure, low-volume cleanerNo window cleaning

Canberra was subject to Stage 1 restrictions from 1 November 2005, which were increased to Stage 2 after a year on 1 November 2006. The continuing drought led to a further increase to Stage 3 from 16 December 2006; the restrictions were maintained at Stage 3 throughout 2007 and 2008. From 1 November 2010 Canberra moved to Permanent Water Saving Rules due to heavy rain bringing water storages close to capacity.

New South Wales

The different classification levels of water restrictions in New South Wales vary widely, and are set by the different authorities responsible for water throughout the state.

Sydney Water Restrictions (2019–present)

Level 1 Restrictions:

In late May 2019, it was announced that Sydney Water will be reinstating Level 1 water restrictions throughout the greater Sydney area.[9] [10] These restrictions began on 1 June 2019, as a result of an extremely dry year. As of 29 May 2019, Greater Sydney water supply levels are 53.4%,[11] which is significantly lower than May 2018, in which supply levels were 73% in major catchments.

Level 2 Restrictions:

On 21 November 2019, the NSW government announced Level 2 water restrictions. These restrictions commenced on 10 December 2019, replacing the level 1 water restrictions. Level 2 restrictions have been brought in earlier than the Metropolitan Water Plan[12] (2017) recommends, with dam levels currently at 46.1%.[13] Premier Gladys Berejiklian, and Minister for Water, Property and Housing, Melinda Pavey announced the restrictions early as a precautionary measure, and to stave off the implementation of Level 3 restrictions later on.[14]

Level 3 Restrictions:

Upon the commencement of the Level 2 water restrictions in December 2019, Minister for Water, Property and Housing, Melinda Pavey announced that Level 3 water restrictions should be expected early in the year of 2020.

Sydney Water Restrictions (2003–2009)

Falling dam levels prompted Sydney Water to impose Level 1 water restrictions on the Sydney area from 1 October 2003.[15] When these restrictions failed to stem the reduction in the city's water supplies as a result of continuing drought, and with dam levels dropping below 50 per cent, Level 2 water restrictions were introduced from 1 June 2004. Further reductions in dam levels to below 40 per cent of capacity led to an increase to Level 3 water restrictions from 1 June 2005. Level 3 water restrictions were in place as of February 2008. Since June 2009, though, Sydney Water replaced water restrictions with Water Wise Rules. The Rules include:[16]

To deal with its water shortage, New South Wales has followed the same path as Western Australia, in which a desalination plant for Sydney was built at an estimated cost of $1.3 billion.[17] The Sydney Desalination Plant is to be turned on when Sydney's drinking water level reaches 60% capacity, and water restrictions will be in place when drinking water reaches 50% capacity.[18]

Sydney Water has imposed fines of $220 for violations of the rules for individuals, $550 for businesses, and $2,200 for water theft.[19] Rules are enforced by Sydney Water staff through random checks.

Regional NSW

As different towns in regional New South Wales take their drinking water from different sources, different levels of water restrictions apply. The levels or stages which apply in certain towns are as follows:

Northern Territory

The Territory's water resources are managed and protected by the Northern Territory (NT) Water Act 1992.[31]

In 2017 the Northern Territory Government introduced Compulsory Water Conservation Measures to the Katherine region to take pressure off of their groundwater supplies. This meant:[32]

The Northern Territory do not currently have any restrictions in place.

Queensland

Some of the details of the different stages of water restrictions which apply in Queensland for the residential sector are as follows:[33]

Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 Stage 7
Reticulation sprinklers:3 days/weekNo sprinklersNo external water use without permit
Sprinkler times:4–8am & 4–8pm
Hose watering of gardens:3 days/weekNo hosing
Hose watering times:4–8am & 4–8pmBefore 7 am & after 7 pm
Bucket/watering can watering times:Any time3 days/week;
4–8am & 4–8pm
No watering lawns;
Otherwise 3 days/week, 4–7pm
Pool filling:Requires approval

3 days/week
4–7pm,
3 days/week
Log required
Hosing hard surfaces:Prohibited at all times
Car/window washing:Hose or bucketBucket onlyBucket only, to wash mirrors, lights & windows

Although some regions of Queensland have had traditionally high rainfalls, some regions of Queensland have been subject to the toughest water restrictions in place in Australia. The highest level of water restrictions reached the drought was stage 7 for Kingaroy.[34] Toowoomba, Brisbane and South East Queensland reached Level 6 restrictions.

On 13 May 2005, 13 local councils in southeast Queensland, including those in Brisbane, agreed to impose Stage 1 water restrictions, due to drying dams.[35] These restrictions were increased to Stage 2 from 3 October 2005, which at the time were described as the "toughest water restrictions in southeast Queensland's history", except the Gold Coast which had been on Stage 5 restrictions since 2004.[36] Stage 3 water restrictions were imposed on the region from 13 June 2006 amid projections that water storage levels would drop to 5% within 26 months.[37] Water restrictions continued to increase, to Stage 4 from 1 November 2006,[38] stage 5 from 10 April 2007, and up to Stage 6 from 23 November 2007.

The Queensland Water Commission has relaxed water restrictions, with the introduction of High Level Water restrictions as of 31 July 2008.[39]

Other towns and regions of Queensland are subject to different levels of water restrictions, as set out below:

South Australia

The different levels of residential water restrictions which have been applied to different regions of South Australia by SA Water are as follows:

Permanent Water Conservation Measures Eyre Peninsula Level 2 Level 3
Reticulation sprinklers:5pm–10am (6pm–10am in DST)6pm–8am (8pm–8am in DST)8pm–8am, 3 days/week. Sporting grounds and public facilities 2 days/week.Prohibited
Hand-held hose watering and drippers:Any time1 day/week with trigger nozzle, 6–9am or 5–8pm
Bucket/watering cans:Any time
Swimming pools and Spas:No restrictionsNo filling or emptying without permit. New pools or spas must have a cover.
Fountains and ponds:Must not be operated and can not be topped up unless they support fish.
Car washing:Bucket, commercial car wash or hose with trigger nozzle onlyBucket or commercial car wash only
Hard surfaces:No washing or hosing down hard surfaces

Different water restrictions levels apply to different parts of the state, depending upon the source of drinking water used in that region. SA Water have produced a map showing the current areas of water restrictions.

Areas using Murray River water

Adelaide and much of south-eastern South Australia takes its drinking water from the Murray River. Permanent water conservation measures were put into place in this region in 2003,[42] and as a result of the most severe drought to hit the region since the 1940s, Level 2 water restrictions were imposed from 22 October 2006 on those areas (including metropolitan Adelaide) which use water from the Murray River.[43] Even lower inflows to the Murray River over the course of 2006 led to the even tougher Level 3 water restrictions being imposed on the region from 1 January 2007,[44] which remain in place.

Other areas

The Eyre Peninsula draws most of its drinking water from underground basins,[45] which progressively became depleted through drought and high consumption, prompting the State Government to introduce water restrictions on the entire region from 6 December 2002, apart from Whyalla. The water restrictions for the peninsula remain in force as of 2008.

Conversely, the areas in the south east of the State, south of the town of Keith, are subject to the permanent water conservation measures.

Other areas in the state are not subject to water restrictions. These areas include Murray Mallee, areas north of Port Augusta, Kangaroo Island, Cockburn, Hawker, Melrose, Ororoo, Parachilna, Quorn, Warooka, Wilmington, Terowie, Yunta, Olary and Manna Hill.

The different levels of residential water restrictions which have been applied to different regions of South Australia by SA Water are as follows:

Permanent Water Conservation Measures Eyre Peninsula Level 2 Level 3Reticulation sprinklers: 5pm–10am (6pm–10am in DST) 6pm–8am (8pm–8am in DST) 8pm–8am, 3 days/week ProhibitedHand-held hose watering and drippers: Any time 1 day/week with trigger nozzle, 6–9am or 5–8pm.

Tasmania

Usually, there are no water restrictions for domestic consumption.

Periodically, however, restrictions will be placed on how water can be used in domestic, commercial or rural areas. Examples[46] of such restrictions are:

One purpose of such restrictions is to keep the dam levels up and ensure adequate water pressure for the fire department's needs in the event of fires.

Victoria

The different stages of water restrictions which apply in different areas of Victoria are based on the Victorian Uniform Drought Water Restriction Guidelines,[48] which, however, have been modified by the inclusion of a Stage 3a, to reduce the likelihood of needing to impose Stage 4 restrictions in metropolitan Melbourne.[49]

Stage 1 Stage 2 Stage 3 Stage 3a Stage 4
Watering lawns:Manual: Any time, any day with the use of a trigger-nozzle hose or bucket. Automatic: 6am–10am and 6pm–10pm on alternating daysWatering lawns is bannedAll outside watering banned
Reticulation watering days:Alternating daysDrippers only, 2 days/week
Automatic reticulation:Midnight–4amMidnight–2am
Manual reticulation:6–8am & 8–10pm6–8am
Hose watering/ buckets/ watering cans:Any time2 days/week, 6–8am & 8–10pm2 days/week, 6–8am
Hosing hard surfaces:Banned at all times
Car washing:Bucket/high pressure cleaner or trigger nozzle hoseBucket/high pressure cleaner onlyBuckets only to clean windows, mirrors and lights
Swimming pools:Filling or topping up pools/spas up to 2000 L permitted. Over 2000 L, permit requiredNo filling

The status of water restrictions in different regions of Victoria is as set out below:

Western Australia

The different stages of water restrictions which can currently be applied in Western Australia are as follows:[55]

Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Stage 6 Stage 7
Reticulation sprinklers:DailyAlternate days3 times/weekTwice weeklyOnce weeklyNo sprinklers
Sprinkler times:Before 9.00 am or after 6.00 pm
Hose watering of gardens:Any timeNo hose watering
Swimming pools:No restrictionNo over-fillingNo topping-upNo filling
Car washing:No restrictionBucket only

Water restrictions have been employed in various Western Australian towns when poor rainfall has led to water shortages. For instance, in the summer of 1977–1978, Perth was subject to a total sprinkler ban.[56] Newman and Nullagine experienced water restrictions from 1991 and 1992 onwards as the result of drought.[57] Similarly, the resort towns of Yallingup and Dunsborough experienced water restrictions in 1997 during a heatwave,[58] and Kalgoorlie-Boulder had temporary water restrictions imposed during 1998 due to shortages in its reservoirs (which contain water pumped through the Goldfields Water Supply Scheme).[59]

A Stage 1 ban on using reticulation sprinklers between 9.00 am and 6.00 pm was imposed on Perth residents in 1996,[60] and remains in place to this day. This was the first water restriction imposed on the state's most populous city since the total sprinkler ban in 1978. From September 2001, users of the Integrated Water Supply Scheme (covering Perth, its surrounds and towns on the Goldfields pipeline) were subject to Stage 4 restrictions, only permitted to use reticulation sprinklers two days per week, according to a roster.

The town of Northampton in the Mid-West encountered a water shortage in 2006 where its underground aquifer could not meet demand. Stage 5 watering restrictions were imposed,[61] and the Water Corporation resorted to carting tankers of water to the town to maintain the supply.[62]

Stage 4 water restrictions were imposed in the South-West towns of Bridgetown, Balingup, Boyup Brook, Hester, Kirup, Greenbushes and Mullalyup from 13 October 2006.

On 1 October 2007, water restrictions were expanded to cover the entire state, including those towns serviced by utilities other than the Water Corporation. Under the new system, all areas of the state in the region south of Kalbarri and Kalgoorlie (including Perth and most of the state's population) which use scheme water are subject to Stage 4 restrictions.[63] Areas north of the dividing line are subject to Stage 2 restrictions.[64] Furthermore, whereas the water restrictions had previously only restricted the use of mains water to water gardens and lawns by sprinkler, under the new water restrictions unlicensed bore operators in Perth and its surrounds are restricted to watering their gardens three times per week.[65] This was to slow the depletion of underground aquifers from which Perth sources much of its drinking water.

Around November 2013 the water restrictions were removed from the Water Agencies (Water Use) Bylaws 2010 and added to the Water Services Regulations 2013[66] [67] [68]

Efforts are being made to secure alternative water sources to ease water shortages in the Integrated Water Supply System. Integral to the Government's strategy is the construction of desalination plants to service Perth. One has already been constructed in Kwinana, which supplies 17% of the city's water consumption and is the largest desalination plant in both the Southern and Eastern hemispheres.[69] A second desalination plant near Binningup was completed in 2011.[70] A trial has also been announced to treat wastewater and pump it into underground aquifers to undergo natural filtration as it returns to the dwindling groundwater supply.[71]

Water storage levels

The Australian Bureau of Meteorology collates national statistics (from 2009 onwards) for water storage levels and makes them available on their water storage web tool and via a water storage iPhone app.

Criticism

Water restrictions have been criticised for hampering the economy and the lifestyles of people.[72] The National Water Commission chief has argued that Australia needs a source of water that is independent of rainfall. Water desalination is touted as the solution for potentially unlimited water use.[73] Former Australian Environment Minister, Malcolm Turnbull says that it does not make sense to have permanent water restrictions just as there are no electricity restrictions.[74]
