Irrigating sporting fields with recycled water

Hunter Water is continuing to make recycled water available to irrigate parks, gardens, sporting fields and many other public spaces.

We are planning to use recycled water to irrigate Jack McLaughlan Oval in Edgeworth.

The recycled water will come from Edgeworth Wastewater Treatment Works, which has been supplying recycled water to Waratah Golf Course for over ten years.

About recycled water

Recycled water is water that has been used before in homes and businesses. It is then treated to a high standard, meeting the requirements of NSW Health, ready to be used again for many different purposes.

Hunter Water already has 16 recycled water schemes providing recycled water for irrigation, agriculture and industry.

In the Hunter region more than 1,000 homes already have recycled water available for toilet flushing, outdoor use and for machine-washing clothes.

Community benefits

Using recycled water will help ensure sporting fields are watered and available to be used all year round, even in the event of a future drought. During a drought, water restrictions would mean that drinking water may not be available to irrigate sporting fields.

Being able to play sport, have green grass on sporting fields, have green gardens and other public spaces is important for the wellbeing of our community.

Project timeline

  1. Early 2022 to mid-2023: Designing the most appropriate path for the pipeline to run from Edgeworth Treatment Works to the sporting fields, while working with Lake Macquarie City Council and the users of Jack McLaughlan Oval to understand their needs
  2. Mid 2024: Start construction on the new pipework
  3. Late 2024 to mid 2025: The pipes are in, the new irrigation system is ready, and we can begin using recycled water at the ovals connected to the water tank

Frequently asked questions

  • What is recycled water?

    Recycled water is water that has been used before in homes and businesses. It is then treated to a high standard, ready to be used again for many different purposes.

    Hunter Water already has 16 recycled water schemes providing recycled water for irrigation, agriculture and industry.

    In the Hunter region more than 1,000 homes already have recycled water available for toilet flushing, outdoor use and for machine-washing clothes.

  • Is recycled water safe?

    Recycled water is treated to a high standard to comply with the Australian Guidelines for Water Recycling and to meet the requirements of NSW Health.

    Different grades of recycled water are suitable for different purposes. The recycled water that would be supplied to Jack McLaughlan Oval will be suitable for ‘municipal use’. This means the water is suitable for irrigation, dust suppression and construction.

    Recycled water is treated to the level required to remove bacteria and viruses.

  • How will the recycled water be used?

    The recycled water will be supplied using the existing irrigation system. The water will reach the fields by underground pipes. This will be an extension of the pipes which already supply recycled water to the nearby golf course.

    Irrigation of the fields will be automated and will generally occur at night. This reduces the amount of water lost to evaporation, especially in hot weather. It is also when the fields are not in use.

  • Is it safe to come into contact with recycled water?

    Recycled water is treated to a high standard. It is important, however, not to come into direct contact with recycled water (for example, it must not be used for washing hands, etc).

  • How will you ensure people don’t come into direct contact with recycled water?

    • All taps, pipes and fittings will be colour-coded purple to be easily recognised.
    • Taps and valve-boxes will need to be opened with a key.
    • Taps, fittings and tanks will have “Do Not Drink” signs.
    • Everyone with access to the recycled water irrigation system will be given training.
    • Signs to ensure users of the fields are aware of recycled water irrigation. Signs will be checked regularly to ensure it remains in place.
    • Council will work with sporting organisations to ensure their members understand recycled water is being used.
  • Why is irrigation with recycled water being considered for sporting fields in Lake Macquarie and other areas?

    Using recycled water will help ensure Jack McLaughlan Oval is watered and available to be used all year round, even in the event of a future drought. During a drought, water restrictions would mean that drinking water may not be available to irrigate sporting fields.

    Being able to play sport, having green grass and flourishing public gardens and greenspace is important for community wellbeing.

  • Where will the recycled water come from?

    The recycled water will come from the Edgeworth Wastewater Treatment Works, which has been supplying recycled water to Waratah Golf Course for over ten years.

  • Will there be changes to how the fields are used?

    There will be no changes to how Jack McLaughlan Oval is used by sporting organisations and the community.

    The recycled water is high-quality and does not require ‘withholding times’. This means the fields can be used as normal without restricting when people use the fields.

  • Will using recycled water affect the soil and grass?

    Using recycled water is not expected to affect the fields and soil testing will occur regularly. Recycled water has been used at Edgeworth Golf Club for over 10 years.
