Surface Water Drainage Systems

WCI designs, installs and maintains all types of SuDS, attenuation and rainharvesting systems.

Surface Water Drainage

Encompassing all forms of rain and stormwater flows, WCI designs and installs surface water drainage networks and Sustainable Drainage Systems (SuDS).

Rainwater Harvesting

Whether for garden irrigation, grey water supply or a fully potable supply, rainwater harvesting is the collection and storage of rainwater for reuse.

Oil Separators

Oil/Water Separators, including full retention and bypass separators, treat surface water run-offs to remove hydrocarbons before dispersal in the environment.


The preferred method for dispersing excess surface water under UK legislation is to ground via a surface water soakaway as defined by BRE Digest 365.

WCI provides professional yet cost-effective access to wastewater engineering where multi-disciplinary engineering services are not required.  There are number of reasons why you might call WCI for support with surface water drainage.  Here are just a few:

You are building a new house and need to discharge a planning condition calling for SuDS management of your surface water.

You are an architect or engineer requiring specialist surface water engineering support on a domestic or commercial project

You are preparing a planning application for a new private or commercial development and require support with the surface water drainage design and submissions

You experience occasional or systematic flooding of your existing property and require a solution

You wish to capture and reuse rainwater from your roofs for garden irrigation, grey water use or as a potable water supply.
