The Benefits of a Surface Infiltration Ditch

Surface infiltration ditches, a distributed infiltration solution along infrastructures

Infiltration techniques can be deployed in natural areas or constructed areas located in permeable soils that capture, store, and infiltrate the volume of stormwater runoff through a granular layer and then into surrounding soil. Surface infiltration ditch acts like swales allowing steeper slopes and a granular layer to manage water infiltration on a longer term. These techniques manage stormwater runoff volumes locally, increase groundwater recharge and provides cooling benefit while being an easy and cost-effective water management solution. Dry surface infiltration ditch can be constructed along roads, urban streets, railways car parks, logistic areas, airports, construction sites and service stations. As hydrocarbon pollution is heavily carried by runoff from roads and trafficked areas, this stormwater management solution should include an efficient treatment before water infiltrates the native permeable soil. 

The added value of aquatextiles 

Why use our TenCate GeoClean® aquatextile in surface infiltration ditches?

  • Systematic oil retention and biodegradation in any weather condition.
  • Designed for distributed water treatment over long distances
  • Applicable to site with high water table.
  • Barrier to deep soil contamination in case of accidental hydrocarbon spillage
  • Easy installation
  • Reuse of clear water for irrigation when the treated water is drained

Installing TenCate GeoClean® aquatextile

Installing TenCate GeoClean® aquatextile in the infiltration ditch is a systematic solution that improves and secures the preliminary water treatment of vegetation and organic topsoil
