Detention & Infiltration


Humes offers two economical detention and infiltration solutions with enhanced design flexibility to meet regulatory requirements.

Most authorities have implemented guidelines around the detention and/or volume reduction for new Water Sensitive Urban Design (WSUD) developments.

StormTrap® System

The StormTrap® system is a purpose-built stormwater detention and infiltration solution that meets regulatory requirements while minimising the impact on land usability. It is the most cost effective, trafficable, below ground detention system on the Australian market today.

The StormTrap® system takes a unique approach, connecting individual precast concrete modules into a configuration that meets each project’s requirements. This delivers a simple and flexible design solution without compromising above ground land use.

The StormTrap® system’s design and installation benefits make it a competitive solution for any residential, commercial or industrial project. It is:

  • custom designed to best suit your project
  • designed using custom software, reducing your design time
  • able to deliver the maximum possible detention volume for the smallest footprint
  • able to deliver a high infiltration capacity
  • below ground and trafficable
  • cost effective in constrained sites
  • quick to install
  • fully accessible and maintainable
  • able to meet local detention requirements without compromising land use.

Soakwells

Humes soakwells are vertical perforated liners which allow stormwater runoff from roofs and hardstand areas to infiltrate into the surrounding substrata.

Humes’ soakwells are available in DN600 to DN1800 and depths from 600 mm to 1,500 mm. We also offer a range of cover options including trafficable or non-trafficable, grated or access chamber cover and surround.
