Compact chains are part of the various chains approved for autonomous sanitation.
These channels are generally reserved for secondary residences.
They consist of an all-pit and a wastewater treatment system that will allow the water to be purified before being either infiltrated or released into the natural environment.
The filter components of these dies replace the old sand filters which were generally very bulky and used a large surface area.
This pathway therefore makes it possible to solve most of the time a surface problem available in the field. They also make it possible not to have to do a major earthwork in your garden every 10 to 15 years, since, at the end of life, the media that composes the filters can be changed in most cases in a fairly simple way.
The different media used for compact filters are: coconut bark, rock wool, hazelnut shells, pine bark or zeolite.
Although these systems also work for the main residences, it is preferable for them to opt for an all-in-one solution: the Micro-sewage treatment plant.
