Drainage Design

Drainage Design

In a period of ever increasing development constraints - both physical and financial - combined with changes to planning legislation and flooding events affecting many areas of the UK, it's never been more important to design developments in a sustainable, cost-effective way.
Aided by our extensive knowledge both of sustainable drainage systems (SuDS) and traditional drainage and infrastructure design, our experienced team of engineers will work closely with you to design, detail and deliver the most cost-effective SuDS to suit your development - ranging from open surface water ponds, constructed wetlands or dry detention basins to filter strips, swales, soakaways and permeable paving. Our own in-house ecologists can also help to create enhanced biodiversity and optimise environmental benefits.
We calculate greenfield and pre/post development run-off rates. We can also design headwalls, culverts and permeable paving. This detailed understanding allows us to liaise with water companies, and with the relevant environmental agencies for discharge consent, to secure statutory approvals and consents and advise on sewer requisition and adoption procedures - including Building Regulations Part H, adoptable Section 104 and drainage diversion Section 185 works.
