What Stormwater Services Australia Pty Ltd does

Stormwater Services Australia Pty Ltd (SSA) is a Sydney-headquartered, privately held Australian proprietary limited company providing end-to-end engineering, construction, maintenance, and advisory services for complex stormwater infrastructure. Founded in February 2017 as OSD Australia by David Nixon and Paul Milic to address the disconnect between stormwater engineering design and real-world operation, the company executed a national expansion in July 2021 by launching eight regional trading entities across Melbourne, Brisbane, Newcastle, Canberra, Adelaide, Darwin, Central Coast, and Wollongong. Stormwater Services Australia Pty Ltd was formally established as the parent entity in November 2023, with subsequent additions including Stormwater Gold Coast, West Sydney Plumbers, and OSD Australia as wholly-owned subsidiaries, operating today through 11+ hyper-local branded entities covering all Australian states and major metropolitan areas.

The company's service portfolio is organised into five pillars: Modelling & Strategic Planning (DRAINS hydraulic modelling, MUSIC water quality modelling, Integrated Water Management plans, flood studies, Stormwater Management Plans); Specialist Advisory & Audit (forensic root cause analysis, NCAT/Court-compliant expert witness reports, asset condition audits, EPA compliance audits, peer review); Civil & Commercial Construction (OSD systems, WSUD bio-retention, GPT installation, public drainage, pump station fit-outs, rectification works); Asset & Facilities Maintenance (programmed maintenance contracts, pump servicing, GPT cleaning, CCTV inspection, industrial trade waste compliance, 24/7 emergency response); and Major Repairs & Rectification (OSD tank repair, collapsed pipe replacement, trenchless CIPP relining, filtration retrofits). Underlying technology includes DRAINS and MUSIC modelling software, BIM/GIS integration (AutoCAD, Revit, ArcGIS, QGIS), Python hydrological analysis, advanced CCTV crawlers with laser profiling, heavy-rigid vacuum trucks, and an IoT remote monitoring partnership with matter.city for continuous data-driven oversight. The company holds ISO 45001, ISO 9001, ISO 14001, and ISO 27001 certifications.

SSA serves State & Local Government, Commercial & Developers, Facilities Managers, Insurance & Legal firms, and Industrial & Manufacturing operators via direct enterprise field sales, project-based professional services fees, and recurring programmed maintenance contracts. Revenue mechanics blend project-based engineering and construction fees with subscription-adjacent multi-year maintenance contracts. GTM combines an extensive Knowledge Centre and technical blog for top-of-funnel education, industry event participation (UDIA forums, IPWEA NSW, Franc.Sydney Platinum sponsorship), and bottom-of-funnel consultation booking through regional branded entities that escalate complex engagements to national SSA. The company also founded and fully funds Stormwater 2030, a dedicated advocacy organisation driving government investment and policy reform in the stormwater sector, with David Nixon serving as Chairman and Chair of the NSW SQID Taskforce.

• Balmoral Group Australia: Australian environmental engineering and WSUD consultancy where Ben Wolfgramm previously held leadership roles. Comparable in Water Sensitive Urban Design, bioretention and wetland engineering, and stormwater quality compliance — same niche and customer segments.
• Optimal Stormwater: Australian specialist stormwater consulting firm where SSA Director Ben Wolfgramm previously held leadership positions. Directly comparable in WSUD design, DRAINS/MUSIC modelling, and stormwater quality improvement advisory — overlapping service portfolio and target client base.
• Australian Wetlands Consulting: Australian specialist wetlands and stormwater consulting firm where Ben Wolfgramm previously held leadership positions. Directly comparable in wetland design, WSUD modelling, and environmental compliance advisory for stormwater assets.

Broad incumbents

• AECOM: Global infrastructure consulting firm with significant Australian water and stormwater practice covering modelling, design, and program management. Overlaps with SSA's engineering and advisory services but operates at much greater scale with broader service portfolio.
• Jacobs Australia: Global engineering and professional services firm with significant Australian water resources and stormwater infrastructure consulting. Comparable in flood modelling, drainage design, and asset management for councils and water authorities.
• WSP Australia: Major global engineering consultancy with substantial Australian water, wastewater, and stormwater infrastructure practice.

• GHD: Major Australian-headquartered global engineering, architecture, and environmental consulting firm offering water, stormwater, and infrastructure services as part of a much broader portfolio. Comparable in hydraulic modelling, drainage design, and asset management for water authorities but competes at much larger scale.
• SMEC (part of Surbana Jurong): Australian-headquartered engineering consultancy with strong water and urban development practice covering stormwater modelling, drainage design, and infrastructure construction. Comparable in stormwater engineering services for government clients across Australia and Asia-Pacific.
• Downer Group: Large Australian infrastructure services company with significant water and civil infrastructure operations including stormwater construction and maintenance. Comparable in civil construction of OSD, drainage, and pump station assets for government and commercial clients, though at much larger scale and broader scope.
