Infiltration Testing: The SuDS Reality Check Every Scheme Needs

Sustainable Drainage Systems (SuDS) live or die on what the ground can actually absorb. Infiltration testing is the reality check that turns drawings into workable details and helps you avoid expensive redesigns once the civils team is mobilised.

EnviroSolution delivers infiltration testing to BRE 365 methodology with clear, site‑specific recommendations. We plan test locations to match proposed soakaways and permeable areas, coordinate permits if needed, and keep results easy to interpret for designers and clients. Where results are marginal, we’ll set out options — from component resizing to alternative SuDS features — so you can make informed, timely choices.

For planning submissions, we package tests with drainage strategies and flood considerations. For contractors, we ensure logistics and safety are sorted, and we’ll align with your programme to minimise disruption. If site history suggests contamination, we can pair testing with Phase 1 Desktop Study and targeted sampling to avoid spreading risk.

Review our EnviroSolution services to see how SuDS, flood risk and geology interplay. Then schedule infiltration testing early enough to steer the design — not just to sign it off.
