Flood Risk and Drainage.

Our Approach

Flood Risk Assessment (FRA) and drainage support from H2Ogeo Ltd helps clients demonstrate that flood risk and surface water management have been properly considered and addressed in line with national and local policy. Whether supporting a planning application or discharging conditions, H2Ogeo prepares FRAs and drainage inputs that are proportionate to the scale of development and tailored to the site, focusing on real flood mechanisms rather than generic statements. This provides regulators with confidence that flood risk will not be increased on or off site.

A key strength of H2Ogeo’s FRA and drainage capability is the integration of ground conditions, groundwater and surface water processes. Assessments consider fluvial, tidal, surface water and groundwater flooding, alongside infiltration feasibility, soil permeability and seasonal groundwater levels. This joined-up approach is particularly valuable where infiltration-based SuDS are proposed, or where sites are constrained by shallow groundwater or complex geology. The outcome is a drainage strategy that is technically sound, realistic to deliver and aligned with regulatory expectations.

H2Ogeo’s FRA and drainage outputs are written to support smooth planning decisions and project delivery. Reports are clearly structured, use consistent terminology and provide unambiguous conclusions that decision-makers can rely on. Drainage layouts, assumptions and design parameters are clearly explained, reducing the risk of follow-up queries or late-stage redesign. For clients, this means clearer approvals, reduced programme risk and confidence that flood risk and drainage will not become barriers as projects progress from planning into construction.
