Water restrictions

Council changes water restrictions to manage sustainable urban water supply. Restriction levels are communicated on a range from Permanent Water Conservation Measures (PWCM) to four, with PWCM being the lowest and four the highest. The level for individual towns is based on indicators including the capacity and level of the towns’ water supply which is detailed in the Water Demand Management Plan 2023 -2028. The restrictions do not apply to greywater, rainwater or private bore water and properties with their own water allocation or licences. The restrictions do not apply to greywater, rainwater or private bore water and properties with their own water allocation or licences.

Frequently asked questions

  • FAQs

    How are water restriction levels determined?

    The level of Fairbairn Dam near Emerald is used as an indicator for water restrictions because it is connected to the Nogoa Mackenzie water scheme that Emerald, Blackwater, Bluff and Tieri rely on for their water supply.

    Rolleston gets its water from the Comet River. It’s water restrictions are determined by the capacity of the Ring Tank.

    Capella is supplied with water from three sources – a system of bores, surface water runoff, water that is harvested from Capella Creek during times of flood flows and from a drought relief pipeline that was constructed from Tieri.

    Its restrictions are determined by the capacity of the water storage facilities.

    What is the current level of the Fairbairn Dam?

    You can check the current level of the dam by visiting the Sunwater website.

    How does the council get its water?

    Every year on 1 July, the council is allocated an amount of water to use to supply the community from the Fairbairn Dam by SunWater.

    If I pay rates, don’t I have the right to use water?

    Owners of property connected to the water supply pay an annual charge and a consumption charge.

    The annual charge is the cost for the council to provide water to the property whether or not any water is actually used.

    The consumption charge is calculated from the amount of water actually used at the property.

    How important is the community water supply?

    Supplying water for people to use is what is referred to as ‘high priority’.

    Other high priority water users are an industry that is vital to the economy of the state and region—employs a lot of people and earns money for the state—such as coal mines.

    Am I an odd or even-numbered property?

    Whether you are an ‘even’ or ‘odd’ numbered property influences your watering days.

    Property addresses are categorised as ‘even’ if:

    • The number of property within the street is an even number. If you live in a unit, it is the number of your unit block that counts, not the number of your unit. E.g. 4 Simon Street or Unit 3/14 Simon Street.
    • There is no allocated street number and the property’s lot number is an even number. E.g Lot 4 Simon Road.
    • The property address includes more than one street number and the first number is even. E.g. 4 – 7 Simon Road.

    The same guidelines apply to categorise ‘odd-numbered’ properties (swap the word ‘even’ for the word ‘odd’).

    What is the council doing to save water?

    The council has reduced its use of water on parks, gardens and playing fields considerably.

    A water-use monitoring system has been implemented requiring monthly water-use reports to be submitted to the council for each facility being watered.

    What about the Emerald Botanic Gardens?

    The Emerald Botanic Gardens is a public park of regional significance.

    It is enjoyed by hundreds of people every day and is a wonderful oasis for residents and tourists.

    As such, the botanic gardens, which is watered with raw water from the Nogoa River, will have watering reduced in some parts, but will be maintained in the best condition possible given the circumstances.

    What is more important – a coal mine or a town?

    They are both equally important. Coal mines employ many people who live in nearby towns.

    Without the town water, there would be no people to work in the mines and without the mines, there would be many fewer people to live in the town.

    This is why the council and industries that share the water work closely together to make sure the water supply is secure.

    What are industries like mining and cotton farming doing to save water?

    Water supply to industries and crop farming is managed by Sunwater.

    Sunwater works closely with their customers, including council, industries and farmers, to carefully manage water allocation to support ongoing water security and business confidence.

    Remember, these companies and their employees are a part of our community too and recognise the need to conserve water.

    How many water restriction levels are there?

    There are five water restriction levels (0,1,2,3 and 4) in the Central Highlands.

    Do I need to have a sign on the front fence if I’m watering lawns with greywater or tanks?

    While not mandatory, it is a good idea to have a sign, so others are aware.

    Can I install a water tank? 

    Yes, please visit our rainwater tank information page and give our plumbing team a call on 1300 242 686.

Water saving tips

Central Highlands Regional Council is a proud subscriber of Smart Water Advice. In collaboration with Smart Approved WaterMark and water utilities and councils from across Australia, we are providing you with a range of tips and resources to help you save water in your home, garden and at work.

🌲 In the garden

Find out when and how to water efficiently in your garden. Discover how to install a rainwater tank and use greywater safely. Design a new garden. Browse Smart WaterMark approved garden products. Discover the most water-efficient method of washing your car and caring for your swimming pool.

🏡 In the home

Explore ways of reducing your water wastage in your kitchen, bathroom, and laundry.

  • Take a tour through the interactive Blue House
  • Bathroom

    Three-quarters of the water used in the bathroom is used for washing ourselves. These days, thanks to high-quality water-efficient technology it is possible to have a great washing experience without using excessive amounts of water.

  • Toilets

    A quarter of all the water we use in the bathroom is flushed down the toilet! It is crazy that we use high quality, treated drinking water to flush toilets. It’s easy to cut down water wastage in this area.

  • Taps

    A running tap wastes over 6 litres a minute. Remember to turn off those taps and fix leaks.

  • Kitchen and laundry

    Cooking, cleaning and washing dishes uses a huge amount of water.

    About 15-20% of all water consumed in the home is used in the laundry, making this room a high consumer of not only water but also energy and detergents. There are many inexpensive ways to save water in the laundry.

  • Leaks

    A continuously running toilet can waste up to 60,000 litres of water per year.

🏭 In a business

Discover how to save water across different parts of the business sector including nurseries, food processing, manufacturing, commercial laundries, the building industry, hospitality, textiles, horticulture and viticulture.

Rainwater tanks

Rainwater tanks are a great way to reduce the demand of the town water supply, reduce stormwater runoff and achieve more sustainable development.

Council supports and encourages the installation of rainwater tanks for new freestanding houses built on properties larger than 250m2 and for new commercial buildings. However, they must meet certain building, plumbing and drainage requirements.

Some of these requirements are:

  • Tanks must be set at one third full and topped up with town water
  • Tanks must be filled via a float at the top of the tank
  •  Rain banks cannot be used unless there is a reduced pressure zone valve installed
  • Tank must be connected to one external tap, all water closets and the cold water tap of the washing machine

For more information on installing a rainwater tank, please contact us and ask to speak with our plumbing team.

The Queensland Development Code (QDC) Part 4.0 Building sustainably, specifies requirements for installing rainwater tanks.

  • Freestanding houses (class 1) - QDC MP 4.2
    • Water must be collected from at least 50 per cent or 100m2 (whichever is lesser) of the roof area.

    • Tanks must have at least 5,000-litre capacity when the property is 250m2 or larger.
    • Tanks must have at least 45,000-litre capacity if the property is in a rural zone where reticulated water is unavailable and it’s connected
  • Commercial buildings (class 5 to 9) - QDC MP 4.3
    • Water must be collected from at least 50 per cent of the roof area.
    • Tanks must be plumbed to toilets (50m2 per pedestal) and outdoor taps.
    • Tanks must at least have a 1,500 litre capacity per pedestal.
