Maintaining the infiltration system

Regularly checking the infiltration/attenuation system will ensure high performance and guarantee the
rapid distribution of surface & rainwater in the event of heavy, high intensity rainfall.
As described above, dirt may reduce the performance of the infiltration/attenuation system. Drops in
performance can be checked using e.g. tests with a defined volume.
The volume and duration for a test can be estimated and compared using the sizing documents according
to DWA A-138.
If the infiltration performance deviates by ≥ 25 %, we would recommend using inspection equipment to
check the system. Coarse particles or dirty geo textile impairing the infiltration performance can be
removed with appropriate high-pressure purging probes. The general condition, for example, correct
installation or changes to the system over time, can also be checked with Inspection equipment.
Local drain Inspection companies can inspect and rinse the systems.
