Water / Drainage / SuDS
CST Group undertake drainage design for storm water and foul water scenarios. Our designs comply with current best management practices and we utilise the MicroDrainage WinDes software packages to produce economic and robust designs.
Current design for stormwater control and discharge recommends the incorporation of SuDS wherever possible. The idea behind SuDS is to try to replicate natural systems that use cost effective solutions with low environmental impact to drain away surface water run-off through collection, storage, and cleaning before allowing it to be released slowly back into the environment, such as into water courses or soak-aways. This is to counter the effects of conventional drainage systems that often allow for flooding, pollution of the environment, with the resultant harm to wildlife. The intention of SuDS solutions should be that of a system that is easy to manage, requiring little or no energy input, resilient to use, and being environmentally as well as aesthetically attractive. Examples of this type of system are reed beds and other wetlandhabitats that collect, store, and filter dirty water along with providing a habitat for wildlife. Sometimes existing sites within the built environment do not provide opportunities for open water storage. In these situations underground attenuation devises can be utilised and located either within hard paved areas or even as part of the building structure.
Originally the term SuDS described the UK approach to sustainable urban drainage systems. These developments may not necessarily be in “urban” areas, and thus the “urban” part of SuDS is now usually dropped to reduce confusion. In addition to directing of stormwater and foul water flows we can offer advice and designs for foul water pumping stations and package treatment units.
