Brabham Estate – a water efficient and sustainable development

RPS provided hydrology consulting and water management services for one of Western Australia’s most water efficient new urban residential estates.

Sustainable planning

Developed by Peet Limited in collaboration with DevelopmentWA, Brabham Estate is located 20 kilometres north east of Perth and has a 6-Star 'Green Star' accreditation. The estate’s lots all have sustainable, waterwise front gardens.

But to achieve water-efficiency, much work was needed to find sustainable water solutions for the new master-planned community. From the outset the project was constrained by a lack of groundwater allocation, due to groundwater shortages in Perth’s north east corridor.

RPS was engaged in the initial planning stages of the project to provide technical hydrogeological assessments to source alternative water supply options and provide cost benefit analysis for each option.

Water efficient solutions

RPS consultants worked with state government authorities and the developer to establish new and sustainable water supply options for Brabham Estate.

The team undertook a range of studies, prepared water supply options assessments, and developed a groundwater allocation trading plan to support the development.

The work at Brabham has had far-reaching benefits including increased knowledge around water allocation trading, aquifer recharge initiatives and mechanisms to reduce development costs.

RPS’ work has included:

  • Hydrology and hydrogeology consulting services
  • Stormwater and flood modelling
  • 2D groundwater modelling to inform the Local Water Management Strategy
  • Urban water management reporting
  • Drainage design
  • Alternative water supply options assessment
  • Groundwater allocation trading strategy
  • Fill minimisation assessment
  • Subsoil harvesting concept engineering design and economic feasibility assessment

Award-winning development

In May 2023, Western Australia’s Water Minister crowned Brabham Estate in the City of Swan the Waterwise Development of the Year. The award is part of the Water Corporation's Waterwise Development Program, which supports developers to implement best-practice water efficiency standards in the design and delivery of new land developments.
