Protecting the environment
Re-infiltration involves returning all or part of the extracted groundwater back into the ground. This form of drainage is used in areas where groundwater drawdown has a negative impact, such as on the natural groundwater balance, potential construction settlements, or to limit soil contamination. The use of re-infiltration can greatly reduce the area of influence of groundwater drawdown.
Our systems
Re-infiltration via wells
Large quantities of groundwater can be returned to the natural soil layers via wells specially constructed for the return of the extracted groundwater.
Re-infiltration via filters
If the quantities of groundwater extracted are not very large or if there is only a limited working area in terms of surface area, the extracted groundwater can be infiltrated into the ground via individual filters.
Areal re-infiltration
If there are no discharge points such as surface water or sewer systems in the vicinity, areal re-infiltration is the best solution. In this case, the discharge pipe is dewatered at a certain distance in an open area. The extracted groundwater is naturally returned to the soil as seepage.
