OUR SERVICES

We model the complete picture of water movement. Using TUFLOW (2D Flood Modelling), we simulate overland flow paths, flood extents, and hazard zones, providing critical data for development planning and flood risk assessment.

We provide compliant, value-engineered drainage and On-Site Detention (OSD) designs. Using DRAINS, we model pit and pipe networks to ensure your system meets all council and authority requirements efficiently.

We take a holistic “Total Water Cycle” approach. Our IWM plans provide a strategic framework for managing potable water, stormwater, and wastewater, helping you achieve ambitious sustainability targets and reduce long-term operational costs.

We produce comprehensive Flood Risk Assessments and catchment-wide studies for public authorities and private developers, identifying hazards and providing clear strategies for mitigation.

We move beyond surface symptoms to identify the precise technical failure mechanism. Using CCTV, dye testing, and hydraulic analysis, we determine if a failure was caused by a design error, construction defect, maintenance negligence, or a capacity exceedance event.

Our senior engineers provide impartial, NCAT and Court-compliant reports for legal and insurance matters. We deliver clear, evidence-based testimony that withstands cross-examination, definitively establishing causation and liability in complex stormwater disputes.

We act as your proactive defense against regulatory action. Our team audits industrial sites for stormwater pollution risks, ensuring your Gross Pollutant Traps (GPTs), bunding, and trade waste systems meet strict EPA and Council obligations.

We act as the “expert’s expert” to review third-party designs before construction. We stress-test hydraulic models and engineering plans to identify constructability issues, reduce unnecessary costs (value engineering), and ensure the design is compliant with local Council controls.

We specialise in the construction of complex, high-volume concrete OSD tanks. From deep excavation and heavy shoring to intricate formwork and trafficable lids, we deliver structural tanks that maximise site yield while meeting strict Council storage and discharge requirements.

We build functional “green” infrastructure, not just garden beds. We construct bio-retention basins, swales, and raingardens with the correct filter media profiles, sub-soil drainage, and scouring protection to ensure they actually treat water and pass Council handover inspections.

We are licensed for works in the public road reserve. Our teams deliver large-scale pipe laying, box culvert installation, and pit construction for subdivision inter-allotment drainage and Council asset upgrades, managing all traffic control and public utility conflicts.

We deliver the complete mechanical and hydraulic fit-out for commercial basements. This includes the installation of dual-pump systems, valve chambers, rising mains, and custom control panels, ensuring your critical flood defence system is robust and compliant.

We provide tailored, calendar-based maintenance schedules for commercial, industrial, and government portfolios. Instead of ad-hoc repairs, our programmed service ensures every pit, pump, and pipe is inspected and cleaned at the optimal frequency to prevent blockages and maintain hydraulic capacity.

Pumps are your primary defense against flooding. Our qualified technicians perform comprehensive electrical and mechanical servicing of basement pump stations, including “wet testing” pumps, checking float switches, cleaning silt from wet wells, and testing control panel logic to ensure redundancy works when needed.

Green assets require specialist care. Our teams maintain bio-retention basins, swales, and wetlands, managing vegetation health, removing invasive weeds, and tilling filter media to ensure the system continues to treat water quality targets as designed.

We diagnose the root cause of drainage issues before they become disasters. Using high-pressure jet blasting to clear blockages and advanced CCTV crawlers to inspect pipe integrity, we identify structural defects, root intrusion, or construction debris that threatens your network.

For high-risk industrial sites, we maintain critical containment infrastructure. This includes servicing oil/water separators, checking bunding integrity, and maintaining wash-bay isolation valves to ensure trade waste agreements are met and pollution incidents are prevented.

We repair failing On-Site Detention (OSD) tanks that are leaking, cracking, or structurally compromised. Our services include concrete spalling repairs, polyurethane injection for leak sealing, and the application of high-performance waterproof membranes to protect building foundations from water ingress.

When pipes collapse beyond the scope of relining, we undertake the heavy civil excavation required to replace them. We manage complex sites with limited access, deep excavation shoring, and the protection of adjacent services (gas, power, water) to safely restore hydraulic capacity.

We upgrade non-compliant or obsolete filtration systems to meet current EPA and Council standards. This includes retrofitting modern filtration cartridges, pollutant traps, or bio-retention media into existing pits to solve pollution issues without building new infrastructure.

We breathe new life into aged pump stations. Our teams replace rusted guide rails, upgrade corroded pipework to stainless steel, and install modern control panels and telemetry systems, restoring reliability to critical flood-defence assets.
