Stormwater and flood engineering in Sydney — OSD, WSUD, drainage and TUFLOW flood modelling for compliant developments across NSW and Australia.
Apex Engineering Corp delivers stormwater and flood engineering that keeps communities safe, dry and compliant, from lot-scale drainage through to catchment-wide flood studies.
Our engineers design on-site detention, water-sensitive urban design (WSUD) and conveyance systems that satisfy council drainage policies, manage water quality and protect downstream catchments.
For flood-affected sites we build hydrologic and hydraulic models to establish flood levels, overland flow paths and afflux, then translate the results into practical, approvable development outcomes.
We work closely with our civil and hydraulic teams so stormwater, drainage and flood mitigation are resolved as one coordinated package rather than competing constraints.
