Integrated water planning in action.

A selection of recent projects demonstrating our integrated planning capability across complex, large-scale water infrastructure programs.

01
Sydney Water (via GHD)
Integrated Catchment Modelling Program
The Challenge

Deliver hydraulic modelling across a complex integrated catchment system spanning wastewater, stormwater and the receiving environment at the scale and rigour required by a Tier 1 utility.

What We Delivered
  • Embedded within the Sydney Water Tier 1 delivery team
  • Delivered calibration, scenario testing and QA/QC across large-scale models
  • Supported strategic planning, growth and regulatory decision-making
🏆 The Outcome

Robust, defensible modelling outcomes and a trusted partnership within Sydney Water’s supply chain.

02
Unitywater
Water Distribution Pressure Reduction & PMA Feasibility
The Challenge

Reduce non-revenue water, improve network performance and extend asset life through targeted pressure management across the Unitywater distribution network.

What We Delivered
  • Identified and assessed Pressure Management Areas (PMAs)
  • Modelled future state to 2031 demand scenarios
  • Defined PRV locations, boundary conditions and capital works
  • Delivered a prioritised, implementation-ready pipeline
🏆 The Outcome

Actionable pressure optimisation program that improves efficiency and delivers long-term savings.

03
Lower Murray Water
Sewerage Servicing Strategies
The Challenge

Plan servicing for multiple rural growth areas and enable development planning and infrastructure staging across the Lower Murray Water service area.

What We Delivered
  • Assessed gravity vs pressure sewer options
  • Defined infrastructure staging aligned to growth triggers
  • Clarified developer vs utility responsibilities
  • Delivered planning-ready strategies supporting rezoning and approvals
🏆 The Outcome

Clear servicing strategies that support growth, streamline approvals and guide investment timing.

04
Tweed Shire Council
Sewer Model Build & Calibration
The Challenge

Deliver a reliable, calibrated model for a complex pumped sewer network to support long-term planning and investment decisions.

What We Delivered
  • Built and calibrated a dynamic model in InfoWorks ICM
  • Modelled pump stations, rising mains and private assets
  • Identified capacity constraints and wet-weather risks
  • Created a long-term planning and decision support platform
🏆 The Outcome

A robust, end-to-end model that underpins confident planning and smarter investment decisions.
