Thoát nước đô thị

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

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 like SC Intergrid™ to mechanically stabilise the foundations of permeable paving systems

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