Infiltration Testing Explained: What You Need to Know

Not sure what infiltration testing involves? Let us explain. An infiltration test is a site-based investigation to determine how quickly rainwater or surface water will soak into the ground. It’s a critical component in SuDS design and often a planning requirement.

The test involves excavating trial pits to a specific depth (usually the proposed soakaway depth), then filling them with water and measuring how long it takes for the water to seep away. This data allows us to calculate the soil’s infiltration rate.

Why is this important? Because incorrect drainage planning can cause long-term water management issues. By commissioning professional infiltration testing, you avoid potential flooding risks and ensure compliance with planning authority requirements.
