What it involves
Infiltration testing measures how quickly water seeps through soil: a number stormwater engineers and on-site wastewater (land capability assessment) designers need before they can size a drainage system or septic field. We run constant-head and falling-head methods across Melbourne, regional Victoria and the Greater Brisbane area, depending on your project brief, delivering seepage and absorption rate data with drainage suitability advice.
Applications
- Stormwater system design
- On-site wastewater (LCA)

Method & standard
Constant-head & falling-head methods, selected per project brief. Carried out to Stormwater & Drainage by Probegeo's MIEAust-certified engineers.
Where we provide this service
Infiltration Testing is available across the Greater Melbourne area and regional Victoria, plus the Greater Brisbane area as a mobile, BPEQ-registered operation.

Common questions
Why do I need infiltration testing for stormwater design?
Stormwater systems — infiltration trenches, soakwells, raingardens — are sized directly off the measured seepage rate. Guessing this number risks an undersized (flooding) or oversized (wasted cost) system.
Is infiltration testing the same as a land capability assessment?
Infiltration testing is a core input to a land capability assessment (LCA), which on-site wastewater/septic system design typically requires — we deliver both as part of the same fieldwork where needed.
