Practical engineering outcomes delivered for utilities, councils, and developers across Australia and New Zealand.
Byron Shire Council required an updated capital plan to inform the location and timing of upgrades across its water and sewerage networks. DWS updated the council's network models within InfoWorks WS Pro and InfoWorks ICM, then developed a comprehensive capital program to guide the strategic roadmap for addressing future water and sewerage network requirements.
Delivered a defensible, staged capital program that equips Byron Shire Council with clear direction for infrastructure investment, ensuring adequate water and sewerage service levels for the community well into the future.
Rapid population growth and major new developments across the Moreton Bay, Sunshine Coast, and Noosa areas required Unitywater to comprehensively review and update its northern water supply network master plans. DWS developed two 30-year master plans to identify current and future service deficiencies and guide capital investment in supply security and network performance.
Delivered staged capital programs for 2026–2051, providing Unitywater with clear servicing strategies for growth, supply security, and operational improvements. The master plans strengthen Unitywater's ability to assess development applications, plan renewals, and calculate infrastructure charges aligned with population growth.
Watercare engaged DWS to provide hydraulic modelling and assessment services for the creation of District Metered Areas (DMAs) and Pressure Management Areas (PMAs) across three key zones: Hobson (Central), Albany (North Shore), and Warkworth (North Auckland). The project underpins Watercare's Smart Systems strategy for improved leakage reduction, pressure management, and long-term network resilience.
Delivered robust DMA/PMA configurations that are hydraulically feasible, operationally efficient, and strategically prioritised for staged implementation — providing Watercare's Smart Systems team with clear recommendations for leakage reduction, pressure management, and long-term network optimisation.
DWS undertook a water network assessment for a proposed new living area in Bowral South, comprising up to 2,750 residential dwellings and a commercial precinct. The project evaluated the capacity of the existing network to service the development and developed a water supply servicing plan identifying infrastructure requirements to maintain current service levels.
Provided Wingecarribee Shire Council with a clear water supply servicing plan for the Bowral South development, identifying the infrastructure upgrades needed to support up to 2,750 new dwellings while maintaining compliance with council service standards.
DWS was engaged to provide a site feasibility assessment for a proposed 51.3-hectare rural land subdivision at Glenquarry, NSW, planned to yield approximately 500 residential lots. The assessment covered water supply, wastewater, and stormwater servicing options to inform early-stage planning and development approvals.
Provided the client with a comprehensive site feasibility assessment covering all servicing options for water, wastewater, and stormwater — supporting informed decision-making for the development approval process and early-stage infrastructure planning.
Redland City Council engaged DWS to re-evaluate pump station diversions that had been integrated into updated Netserv models, in preparation for the council's Netserv Plan submission. The project addressed potential deviations from the original diversion plan and assessed the impacts of proposed network changes on the ultimate sewerage catchment scenario.
Provided Redland City Council with updated hydraulic model outputs and a clear summary of changes to the Netserv program, supporting a timely and well-evidenced Netserv Plan submission.
DWS was engaged by the City of Kalgoorlie-Boulder to develop a fit-for-purpose sewerage collection systems model to support ongoing network planning and assessment. The project included initial model development, calibration, and a series of capacity assessments evaluating the impacts of proposed developments on the existing sewer network.
Delivered a robust, fit-for-purpose sewerage collection system model and a series of targeted capacity assessments, enabling the City of Kalgoorlie-Boulder to make informed infrastructure decisions and efficiently evaluate development proposals as the city continues to grow.
DWS was engaged by GANDEN Engineers to assess the water, recycled water, and sewer infrastructure networks associated with a large proposed industrial development in Brendale, Queensland. The project evaluated existing network capacity and identified the infrastructure implications of the development under multiple recycled water supply scenarios.
Provided GANDEN Engineers and Unitywater with a comprehensive infrastructure assessment for the Brendale industrial development, identifying network capacity constraints and recycled water supply options — supporting sound infrastructure planning and development approval outcomes.
Internal audits identified significant gaps in Seqwater's model governance, with risks arising from undocumented assumptions, outdated model versions, and inconsistent validation practices. DWS developed a high-level Model Strategy to strengthen governance, reduce risk, and ensure Seqwater's analytical models remain auditable, reliable, and fit-for-purpose across their full lifecycle.
Equipped Seqwater with a clear governance framework for all critical models, reducing risk exposure and ensuring compliance with audit standards. The accompanying roadmap positions Seqwater to adopt advanced modelling technologies and confidently address future challenges including population growth, climate change, and infrastructure expansion.
The Mt Crosby water treatment plants (East Bank and West Bank) are critical to the South East Queensland Water Grid, supplying more than half of Brisbane and Ipswich's daily water. Seqwater engaged DWS to complete an additional water balance assessment to confirm Mt Crosby's minimum supply requirements across a range of water restriction scenarios, underpinned by the Interim Integrated Master Plan (IIMP) assumptions.
Delivered a robust water balance assessment confirming Mt Crosby's minimum supply requirements under the revised IIMP assumptions and updated demand set, providing Seqwater with the evidence base needed for sound operational and investment planning across a range of supply restriction scenarios.
WSP teamed up with DWS to examine the benefits of live operational network models for Unitywater and to perform a technical gap analysis and roadmap for the potential future adoption of live hydraulic modelling across Unitywater's water and sewerage networks.
Provided Unitywater with a clear understanding of the benefits, data requirements, and implementation pathway for transitioning to live operational hydraulic models — equipping the utility with a practical roadmap to enhance real-time network management and decision-making capability.
