Areas We Service | Civil & Stormwater Engineers Across Sydney & NSW

Contrive Consultants provides civil, stormwater and development engineering across Sydney and New South Wales. We have prepared drainage plans, on-site detention (OSD) designs, water quality models and full consultant packages in more than 80 suburbs and growth areas, and we work with builders, developers, architects and homeowners in every one of them.

Choose your suburb below for local council requirements, typical stormwater and OSD triggers, and how our group can help on your site. Can’t see your area? We service the whole of NSW — call +61 497 848 111 or get in touch and we’ll confirm the requirements for your address.

Explore our engineering services, from stormwater drainage design and on-site detention to flood risk assessment and development engineering.

The Hills Shire & Hawkesbury

Our home turf. From the Box Hill and Gables release areas to established Kellyville and Rouse Hill, we know The Hills Shire and Hawkesbury drainage and OSD standards from daily practice.

Blacktown & Greater West

Blacktown, Cumberland and Parramatta LGAs cover many of Sydney’s busiest infill and greenfield corridors, each with their own OSD and stormwater submission requirements.

South-West Sydney

The Liverpool, Camden, Campbelltown and Wollondilly growth corridor, including the Aerotropolis precincts, is where much of Sydney’s new housing is being delivered.

Penrith & Blue Mountains

Penrith’s release areas and the constrained lots of the Blue Mountains both demand careful stormwater and overland-flow design.

Central Coast

Gosford, Wyong and the coastal towns between, where Central Coast Council’s controls and coastal drainage shape every design.

Hunter & Newcastle

Newcastle, Lake Macquarie, Maitland and the wider Hunter, serviced remotely with the same documentation quality as our Sydney work.

Illawarra & South Coast

Wollongong, Shellharbour and the South Coast, where escarpment runoff and coastal discharge points drive the engineering.

Other NSW Growth & Regional Areas

We also prepare civil and stormwater documentation for growth and regional areas right across NSW, working remotely with fast digital turnaround.

Statewide engineering, local knowledge

Wherever your project sits, you get the same complete documentation and the same coordinated group of consultants — civil and stormwater engineering, town planning, architecture, surveying, thermal and telecommunications design.
