Our key clients include businesses from
State & Local GovernmenT
Strategic Partners for Public Infrastructure
Delivering long-term value, compliance, and sustainability for public stormwater assets.
We provide high-level advisory, strategic modelling, and civil construction services to government bodies and water authorities, helping you manage public assets, protect the community, and shape future-ready policy.
Our Solutions for Government:
Catchment-Scale Flood Studies (TUFLOW)
Commission us to conduct large-scale flood and overland flow modelling to inform your future planning controls, development zonings, and capital works budgets.
Policy & Strategy Advisory
We consult directly with state and local government to help draft, review, and refine Stormwater Management Plans (SMPs), technical specifications, and urban planning controls.
Peer Review of Third-Party Designs
Act as your “expert’s expert” to review DA submissions and external engineering plans (MUSIC, DRAINS) for compliance and technical best practice before you grant approval.
Portfolio Asset Management
We provide portfolio-wide condition audits, data analysis, and long-term capital expenditure (CAPEX) forecasting to inform your Asset Management Plan (AMP).
Civil & WSUD Construction
Our construction division is fully equipped to deliver public works, including bioretention basins, wetlands, gross pollutant traps (GPTs), and large-scale drainage upgrades.
Insurance & Legal
Independent Forensic Expertise for Complex Claims & Disputes
Data-driven root cause analysis and expert witness testimony to definitively establish causation and liability.
In complex stormwater disputes, ambiguity is the enemy. Insurers and legal teams require more than just an opinion; they need scientifically defensible evidence. We provide the forensic engineering and technical authority to cut through the noise, determining the exact source, cause, and scope of stormwater failure.
Key Services
Forensic Root Cause Analysis
We move beyond surface symptoms to identify the precise technical failure mechanism. Using CCTV, dye testing, and hydraulic modelling, we determine if the cause is a design error, construction defect, or maintenance negligence.
Expert Witness Services
Our senior engineers provide impartial, NCAT and Court-compliant reports. We deliver clear, evidence-based testimony that withstands cross-examination, supporting legal teams in tribunals and higher courts.
Causation & Liability Assessment
We use historical rainfall data and site testing to definitively separate distinct events—distinguishing between storm damage, pre-existing wear and tear, and non-compliant workmanship to clarify liability exposure.
Rectification & Quantum Reports
Beyond identifying the fault, we provide detailed, compliant scopes of work and accurate cost estimates for rectification, helping insurers and parties accurately quantify the value of the claim or dispute.
Facilities Managers
Proactive Asset Management for Critical Facilities
Minimise operational risk and ensure 100% compliance with programmed national maintenance contracts.
Facilities managers cannot afford unexpected downtime or compliance breaches. We transition your portfolio from costly reactive repairs to a strategic, data-driven maintenance model. Whether managing a hospital network, university campus, or commercial portfolio, we ensure your stormwater infrastructure is safe, compliant, and performing to design capacity.
Key Services
Programmed Maintenance Contracts
Move beyond “fix on fail.” We design bespoke preventative maintenance schedules for pumps, On-Site Detention (OSD) systems, and filtration units to extend asset life and prevent critical failures before they impact operations.
Comprehensive Asset Audits
Know exactly what you own and its condition. We create detailed digital asset registers and condition reports, giving you total visibility over your portfolio’s compliance status and maintenance history.
Regulatory & EPA Compliance
We manage the complexity of Council and EPA regulations for you. From water quality testing to WSUD validation, we provide the necessary certification and reporting to satisfy strict internal and external audits.
CAPEX Budget Forecasting
Avoid budget shocks. We provide long-term lifecycle analysis and replacement forecasting, giving you the data-backed evidence needed to secure CAPEX budgets for critical infrastructure upgrades.
24/7 Priority Emergency Response
When severe weather hits, our contract clients come first. We provide guaranteed priority response to mitigate flooding risks, minimising liability and ensuring business continuity for your tenants.
Commercial & Developers
Your End-to-End DA to Handover Partner
We provide the integrated modelling, engineering, and construction to get your project approved, built, and certified.
We streamline your project by providing a single point of accountability for all stormwater compliance. From the initial Stormwater Management Plan to the final OSD construction, our team de-risks your project and ensures a seamless path to certification. We eliminate the gap between design and delivery, ensuring what is drawn is exactly what gets built.
Key Services
DA & CC Design Approvals
We deliver comprehensive Stormwater Management Plans (SMPs) and detailed engineering designs that navigate complex Council requirements. Our goal is to secure your Development Application (DA) and Construction Certificate (CC) approvals without unnecessary delays or RFIs.
Advanced Modelling & Value Engineering
Using industry-standard software (DRAINS, MUSIC, TUFLOW), we model and optimise your system. We don’t just seek compliance; we value-engineer designs to minimise excavation costs and maximise developable land, saving your project budget.
Civil Construction (OSD & WSUD)
We bridge the gap between design and delivery. Our internal civil teams are experts in constructing complex On-Site Detention (OSD) tanks, bio-retention basins, and Gross Pollutant Traps (GPTs) exactly to specification, ensuring structural integrity and function.
Certification & Occupation Certificate (OC)
We manage the critical path to your Occupation Certificate. From Work-As-Executed (WAE) surveys to hydraulic certification and positive covenants, we handle the final compliance hurdles so you can hand over the asset with confidence.
Defect Minimisation & Accountability
By integrating design and construction, we eliminate the “blame game” between consultants and contractors. We take full accountability for the system’s performance, significantly reducing defect liability risks and rectification costs post-completion.
Industrial & Manufacturing
Safeguarding Industrial Operations & Environmental Compliance
Ensure strict EPA compliance and business continuity with specialist industrial stormwater management.
Industrial sites face unique, high-stakes challenges. A single pollution event can lead to severe EPA fines, operational shutdowns, and reputational damage. We partner with Site Managers and EHS teams to manage these risks, ensuring your drainage infrastructure, trade waste systems, and pollutant traps are functioning, compliant, and audit-ready.
Key Services
EPA & Regulatory Compliance Audits
We act as your proactive defense against regulatory action. Our engineers conduct detailed site audits to identify non-compliant discharges, potential pollution vectors, and infrastructure defects before they result in a fine or notice.
GPT & Oil/Water Separator Maintenance
Industrial sites rely on complex filtration. We provide specialist cleaning and servicing for Gross Pollutant Traps (GPTs), oil/water separators, and Humeceptors, ensuring they effectively remove contaminants from your site’s runoff.
Spill Containment & Trade Waste Solutions
We design and install critical containment infrastructure, including wash bays, bunding, and isolation valves. Our systems ensure that accidental spills or trade waste by-products are captured on-site and never enter the public stormwater network.
Water Quality Monitoring & Testing
Verify your environmental performance with data. We establish regular water quality monitoring regimes, testing discharge for pH, suspended solids, and heavy metals to prove ongoing compliance with your environmental license conditions.
24/7 Priority Emergency Response
Industrial sites endure heavy loads. We specialise in repairing and upgrading heavy-duty stormwater assets, including concrete pits, grated drains, and pipes damaged by heavy forklifts and truck movements, ensuring site safety and longevity.
