Invinity’s 20.7 MWh vanadium flow-battery project, part of the UK Government’s Longer Duration Energy Storage Demonstration Programme, needed urgent infiltration data to finalise its drainage layout and SuDS design.

What we established

Infiltration coefficients were established at the target horizons, giving the engineering team the site-specific rates it needed.

What changed

The report was delivered ahead of programme, allowing the engineering team to finalise the drainage layout and SuDS design against critical deadlines.

How we got there

Rapid mobilisation with trial pits to confirm subsurface conditions and infiltration horizons
Multiple BRE 365 test cycles to determine infiltration coefficients
Hydrogeological observations of soil moisture, groundwater depth and drainage behaviour
Concise BRE 365 report issued within days of testing

Drainage evidence that kept a national energy storage project on programme
