Changes

Where the erosion rate is high and the risk of clogging is significant, it is preferable that the soil above the infiltration well not be tilled. A minimum radius of 3 m around the well is therefore grassed over to filter the soil particles and create a buffer zone between the tilled soil and the infiltration well. The well can also be covered with rock (e.g. clean 100- mm rock) to finalize the installation.
