Održiva urbana drenaža - SUDS

Traditionally, the typical urban area has been built with large impermeable surfaces and underground pipe drainage systems designed to discharge surface water in quantity, but without giving much regard, if any, to water quality or surrounding wildlife. Now there is increasing emphasis on taking a more holistic approach, with less impact on the wider environment, to attenuate the flow at source and improve the quality of water discharged using Sustainable Urban Drainage Systems (SUDS).

The idea is to take a flexible approach and replicate natural drainage to take away dirty and surface water run-off, collecting, storing and cleaning it before releasing it slowly back into the environment, often via watercourses.

SUDS should use little or no energy (other than sunlight), be easy to manage, resilient and environmentally and aesthetically attractive. Such systems can be designed to work in most urban settings, from hard-surfaced areas to soft landscaped features, and can incorporate a range of different components and methods of control:

  • Filter strips and swales
  • Permeable surfaces and filter drains
  • Infiltration devices
  • Basins and ponds

For over 30 years, Tensar’s innovative solutions have developed an enviable environmental record across the world, and a range of case studies and brochures is available for your review. Our experienced engineers can help to advise you on the best choice for your project – you can even calculate the carbon savings which can be made by you by making use of Tensar TriAx on your project with our Carbon Calculator.

How Tensar can help

Tensar has a range of products that can prove integral to a SUDS drainage design. Essentially, they fall into two categories:

Structural improvement of porous pavements using Tensar’s innovative geogrids to mechanically stabilise the foundations of permeable paving systems

Erosion control of channels   using various erosion control mats for swales, ditches and ponds, including TensarVMax erosion mat, to help natural vegetation establish and then to enhance its erosion resistance to occasional water inundation
