Drainage Design Engineers
Water will always find a way. We make sure it goes where it should – with sensible drainage design that keeps regulators happy, risk under control and projects moving once boots are on the ground.

Good drainage starts with understanding how water actually behaves on a site, not just how it’s drawn. We design foul and surface water systems that collect, control and discharge water properly – with layouts, levels and capacities that work when it comes time to dig.
Our drainage designs are shaped by how sites are really built. By getting involved early and coordinating closely with highways, structures and utilities, we help avoid clashes, reduce delays and keep things moving once work starts.
It’s why we’re trusted as drainage design specialists on commercial developments where clear decisions, joined-up thinking and smooth delivery make all the difference.
Good drainage design isn’t about passing a check today – it’s about avoiding problems years down the line. We design drainage with flood risk, resilience and long-term performance firmly in mind, meeting Building Regulations, local authority requirements and SuDS best practice as standard. But we don’t stop there.
We think about where water goes when systems are pushed, how they’ll be accessed and maintained, and how they’ll cope as the site changes over time. Everything is shaped by real ground conditions, carefully coordinated with highways, structures and civil works, and checked in-house before it reaches site. The result is drainage that gets approvals over the line, manages risk sensibly and keeps doing its job quietly long after the build is finished.
On new sites, early drainage decisions shape planning, cost and programme. We design clear drainage strategies that support approvals and keep construction moving, including:
On developed or live sites, drainage needs a more careful approach. We support:
Whether it’s a blank canvas or a site with history, our approach stays the same: sensible drainage design, thought through properly, that works on site and stands up over time.
A drainage design specialist makes sure water goes where it should – safely, legally and without causing problems later on. We plan and design surface water and foul drainage systems that suit the site, meet regulations and protect the building, surrounding land and downstream networks.
Early. The earlier drainage is considered, the more influence it has on layout, levels and overall site design. Getting us involved from the start helps smooth the planning process, avoids late redesigns and keeps programmes on track once construction begins.
Yes. We prepare drainage strategies, calculations and drawings to support planning submissions and the discharge of planning conditions. Our designs are aligned with local authority requirements, Lead Local Flood Authority (LLFA) expectations and SuDS guidance.
We can – and we often do. Many drainage projects involve constrained, operational or partially developed sites. We design solutions that work around limited access, existing services and ongoing site activity, always with an eye on safety, sequencing and minimising disruption.
Absolutely. We review drainage designs to assess compliance, buildability and performance, offering clear, independent advice where needed.
Yes. We design SuDS features such as attenuation tanks, ponds, swales and permeable paving, and assess exceedance routes and flood risk as part of the wider drainage strategy. The focus is always on solutions that work in practice and are maintainable long term.
Absolutely. Drainage rarely sits in isolation. We coordinate closely with highways layouts, levels, structures and existing utilities to avoid clashes and ensure designs are practical to build.
