Gympie Water Resilience and Augmentation Program

Mary River

The Gympie Water Resilience and Augmentation Program, known as GWRAP, is a long-term program of water infrastructure investment to help secure safe and reliable drinking water for the Gympie region.

Gympie Regional Council currently supplies drinking water to nearly 15,000 residential and commercial properties across eight separate water supply schemes.

Some of the critical infrastructure supporting these schemes is aging and becoming less reliable. Investment is needed to manage emerging risks, improve the resilience of the water supply system and support the region’s future growth.

GWRAP forms part of Council’s broader Water Security Strategy and identifies the priority infrastructure needed to improve water supply reliability and resilience over time.

The program will be delivered by Gympie Regional Council’s Water Alliance, comprising of SRG Global and WSP.

GWRAP will help to:

  • address urgent reliability risks within the existing water supply system
  • improve system resilience and operational efficiency
  • support future population growth and economic development
  • reduce reliance on aging infrastructure
  • deliver better long-term value through coordinated infrastructure investment
  • strengthen the region’s ability to respond to drought, outages and extreme weather.

Why is this investment needed?

Aging critical infrastructure

Key assets within the Gympie water supply system are approaching the end of their operational life. The Jones Hill Water Treatment Plant, which supplies the majority of the region’s drinking water, requires upgrades to manage emerging asset risks and support its ongoing reliability. Several smaller treatment plants in the Mary Valley are experiencing process and equipment reliability challenges, which can affect operational flexibility and long-term service reliability

Future population and economic growth

The Gympie region is expected to continue growing over the coming decades. Continued investment will be needed to keep the water supply system reliable, address process and equipment issues, and support future demand and service expectations. Upgrading infrastructure now will help ensure the region has the capacity needed to support communities, local industry and future growth.

Improving system resilience

The current network relies on several small, standalone treatment plants, which increases operational complexity and limits its flexibility during outages, drought and extreme weather events. A more connected system will improve reliability, strengthen resilience and reduce long-term operating costs.

What benefits do these projects bring to the Gympie region?

  • Long-term drinking water security and reliability
  • Improved system resilience during drought and extreme weather
  • Support for future population and economic growth
  • Reduced reliance on aging infrastructure
  • Improved operational efficiency and reduce long-term costs
  • Enable better coordination of regional infrastructure investment

Most importantly, the program will ensure the Gympie region continues to have safe, reliable drinking water for generations to come

 

What is the program scope?

GWRAP includes four priority areas of investment:

  • Immediate reliability upgrades at Jones Hill
  • Connecting the Gympie and Mary Valley water supply schemes
  • Future Gympie Water Treatment Plant upgrade

     

     

 

What is the program timeline?

Short term — up to five years

  • Jones Hill Water Treatment Plant reliability upgrades
  • Planning and design for the future Gympie Water Treatment Plant upgrade
  • Planning and design for the Gympie–Mary Valley trunk infrastructure

Medium term — five to 10 years

  • Construction of the Gympie–Mary Valley trunk infrastructure
  • Decommissioning of smaller Mary Valley treatment plants
  • Completion of the Gympie Water Treatment Plant upgrade or replacement

Long term — more than 10 years

  • Investigation and potential delivery of additional bulk water storage
  • Ongoing improvements to the regional water supply network

Timing will depend on further investigations, approvals, funding and future Council decisions.
