Stormwater Concept Plans

Stormwater concept plans form the early-stage drainage strategy that councils and certifiers use to verify feasibility before hydraulic engineers finalise detailed design.

What is a stormwater concept plan?

  • Collects rainfall from roofs and hard surfaces
  • Conveys water through pipes and drains
  • Connects to council drainage systems
  • Manages overland flow
  • Prevents discharge onto neighbouring properties

Plans include

  • Roof and hardstand catchment areas
  • Proposed stormwater routing
  • Legal Point of Discharge notes
  • Overland flow considerations
  • On-site detention notes where required
