Location

3.1.1 Distance to buildings
A total of four different scenarios can be distinguished with regard to the distance to buildings and fixed
installations.
Firstly, it is necessary to check whether the system is for infiltration or retention. Whilst possible damage
caused by escaping water must be taken into account for an infiltration system, this can be ignored for a
retention system.
Secondly, the installation situation must be checked. If the infiltration or retention system or even the up-
stream filter is deeper than the foundations of neighbouring buildings, the load transfer from surrounding
buildings or foundations or public roads must also be considered. Under no circumstances should the
infiltration ditch modules and external filters be within the load transfer range. This also applies to
any upstream filters.
