Traditional Large infiltration packages

To know if you can use an infiltration or soil bed, a test pit needs to be dug and a simple percolation test done that gives a LTAR value that should be higher than 15 for infiltration to work.

Infiltration or ground bed – what should I have?

Infiltration beds are the most common type of post-treatment stage. The ability of the soil to receive the wastewater determines whether such a facility can be used.
In the infiltration bed, treatment takes place at the bottom of the macadam layer, the sand and in the surrounding soil layers.

An infiltration or soil bed facility can be constructed as a uniform field, in which case the distance between pipes is 1.5 m. Alternatively, they can be constructed as separate trenches with a pipe spacing of approximately 2 m.

To know if you can use an infiltration or soil bed, a test pit needs to be dug and a simple percolation test done that gives a LTAR value that should be higher than 15 for infiltration to work.

A new requirement is that the property owner or supervisory authority must be able to check that the infiltration or ground bed is not in the groundwater, for which the facility needs to have a so-called groundwater pipe included in the package.

If you have problems with space, use biomodules or treatment plants.
