Wamuran Recycled Water Irrigation Scheme

Wamuran, Queensland, Australia


2019 – Ongoing

AU$61 million

Pensar has spearheaded a groundbreaking water recycling and sustainable irrigation strategy for a rapidly developing population centre and food bowl region in South-East Queensland.

The scheme sees Pensar designing, building, operating and maintaining a 40 km pipeline network that taps growing recycled water supply and demand to deliver some 2.6 gigalitres of Class A water per year to the region’s growers.

  • The project includes upgrading the existing sewage treatment plant, the design and construction of a reverse osmosis water treatment plant, supply interfaces, pumping stations, water reservoir, balancing tanks and 40 km of distribution pipeline infrastructure.
  • An integrated solar PV system is also proposed to offset the system’s energy needs.
  • Pensar led the initiative as a joint venture with local growers, then assembled a specialist team to work with Unitywater to develop the concept.
  • The scheme provides local fruit and vegetable growers with climate-independent irrigation, while reducing demand on dams and creeks, and diverting discharge into local river systems.
  • The scheme provides Unitywater with an efficient solution for water reuse and sustainable irrigation.
  • Pensar will operate and maintain the scheme on behalf of Unitywater.

“The Wamuran Irrigation Scheme is a great demonstration of how working with local industry and rethinking how we use and reuse resources can deliver sustainable infrastructure solutions for high-growth urban areas – and mutual benefits for our communities, utilities and the world we live in.”
