Where we work
We are drainage engineers and civil engineering designers working across Staffordshire. We have delivered 11 projects here — drainage strategies, SuDS reports, flood risk assessments and highway design, prepared for planning and taken through to approval.
You do not need a consultant down the road from your site. This is desk work built on survey data, ground testing and the local authority’s own standards. What matters is that whoever does it knows what Staffordshire County Council and Stoke-on-Trent City Council asks for, and what the ground in Staffordshire will actually do.

Civil engineering design in Staffordshire
- Drainage design in Staffordshire — surface water and foul drainage strategies, attenuation, SuDS and outfall design, sized for your site and your discharge rate.
- SuDS design — sustainable drainage design and the SuDS statement your planning authority expects, with the drainage hierarchy worked through in order.
- Flood risk assessments — site-specific flood risk assessments for sites in Flood Zones 2 and 3, and for sites over a hectare in Zone 1.
- Highway design — access, visibility splays, turning heads and adoptable road design, including Section 38 and Section 278 agreements.
- Percolation testing — BRE 365 soakaway testing across Staffordshire, arranged through PT (West Midlands) Ltd so the design and the testing come from one place.
Ground conditions in Staffordshire
Staffordshire spans the Sherwood Sandstone and Mercia Mudstone of the Midlands plain, with the North Staffordshire Coal Measures in the north. The plain is covered by thick glacial till from the late Pleistocene, which produces heavy clay soils and, for drainage, usually means infiltration is off the table even where permeable sandstone sits below it.
None of that tells us what is under your plot, and no report should pretend otherwise. It tells us what to expect, what to test for, and whether to plan for infiltration or for attenuation and a restricted discharge. A percolation test to BRE 365 settles it, and it is cheaper to do that before the design than to redesign afterwards.

The drainage hierarchy
- 1InfiltrationSoakaway or infiltration basin, if the ground takes it
- 2WatercourseDischarge to a surface water body, usually rate-restricted
- 3Surface water sewerWhere a public surface water sewer exists and has capacity
- 4Combined sewerLast resort, and increasingly refused outright
Every scheme has to work down this list in order, and show why each option above the chosen one was ruled out. The ground is what decides whether you get to stop at step one.

What Staffordshire County Council expects
Staffordshire commits to responding to planning applications within 21 days as statutory consultee, which is unusually specific and worth planning around. For sites under one hectare in Flood Zone 1 with no surface water constraints shown, they accept a short proforma rather than a full strategy.
Their SuDS Handbook sets the local design standards. Stoke-on-Trent City Council is a separate lead local flood authority covering the city.

SuDS design in Staffordshire
Drainage is the bulk of what we do, but in Staffordshire a large share of it comes with SuDS design attached — because thick glacial till over most of the county means attenuation rather than soakaways on the majority of sites.
Where infiltration is out, the scheme becomes attenuation: storage sized for the critical storm, a flow control set to the discharge rate Staffordshire County Council will allow, and treatment stages appropriate to what the water has run over. Done well that is basins, swales and permeable surfacing doing visible work in Staffordshire, rather than a tank buried under a car park doing the minimum.
We do this as part of the same job, so the SuDS design and the drainage strategy agree with each other rather than being written by two firms who never spoke. More on SuDS design.
What you need, and when
The work is not one document handed in once. It arrives in stages, and sending the wrong level of detail at the wrong stage is one of the commonest reasons an application stalls with Staffordshire County Council.
- Outline application. A strategy showing the principle: where the water goes, roughly what it will take, and that the site can be drained at all. Detailed calculations are not expected yet, but a strategy that ignores the discharge hierarchy will be questioned.
- Full application. The full surface water and foul scheme with calculations, layout, attenuation volumes and the discharge rate you are asking for, evidenced.
- Reserved matters. The detail that was reserved at outline, now built out against the approved strategy — and it has to match it.
- Discharge of conditions. The final submission against the wording of the condition itself, with the maintenance and management arrangements Staffordshire County Council asks for. This is the stage most people reach us at, often with a condition already imposed.
Where the work lands
- OutlineDrainage strategy: the principle, not the detail
- FullFull scheme, with calculations and discharge rate
- Reserved mattersThe detail, matching the approved strategy
- DischargeSubmission against the condition wording itself
Most people reach us at the last step, with a condition already imposed. That is fine — it is just cheaper to have got the strategy right at the first.
Typical conditions we discharge in Staffordshire
Exact wording varies between officers and between applications, but conditions on sites here almost always fall into three shapes:
- Surface water drainage. “No development shall commence until a detailed surface water drainage scheme, based on sustainable drainage principles and an assessment of the hydrological and hydrogeological context of the development, has been submitted to and approved in writing by the Local Planning Authority.” This is the one that needs the percolation results and the attenuation calculations.
- Foul drainage. A scheme for foul water disposal, agreed before occupation — straightforward on a mains connection, considerably less so on a package treatment plant or where the sewer is at capacity.
- Management and maintenance. A plan setting out who maintains the drainage for the lifetime of the development, and how. Often overlooked, and a common reason a discharge application comes back.
If you have a condition in front of you, send us the wording. We will tell you what it actually requires, before you commit to anything. There is a fuller guide to drainage planning conditions if you want to read up first.

Questions we get asked in Staffordshire
Do you need to be local to do this work?
No. It is done from survey data, ground investigation and Staffordshire County Council’s own standards, none of which require us to be nearby. Being the right distance from your site has never discharged a condition; knowing what the authority wants has.
Who is the lead local flood authority for my site?
Staffordshire County Council and Stoke-on-Trent City Council. They are a statutory consultee on surface water drainage for major development, and they set the local standards and the discharge rate your scheme is judged against.
Can I use a soakaway?
Often not, here — see the ground conditions above. That is a normal outcome, not a failure. Where infiltration is not viable we design attenuation with a restricted discharge, which is what most schemes in Staffordshire end up with.
What counts as a SuDS scheme?
Not just a tank in the ground. Staffordshire County Council expects the drainage hierarchy worked through in order, with water quality and amenity considered, and a maintenance plan naming who looks after it for the lifetime of the development.
What holds a drainage scheme up?
Usually the ground testing, and where one is needed, the response time from Staffordshire County Council or the water company — not the design itself. Getting the testing booked early is the single biggest thing you can do to keep a scheme moving.
I already have a planning condition. Can you deal with it?
Yes, and it is most of what we do. Send us the condition wording and the site address and we will tell you what is needed to discharge it.
