Drainage wastewater treatment plants

In the drainage treatment plant the sewage is deliverd to the septic tank through a sewer pipe. In the settling tank the sewage is pre-treated under anaerobic conditions. The pre-treated sewage is then evenly distributed to the drainage threads through the the well distribution. The process of aerobic wastewater treatment takes place in the drainage pipes, from where the neutralized sewage can freely seep into the ground. At the end of the infiltration drainage, there is a collecting well, whose task is to aerate all drains. You can read more about the types of sewage treatment plants here.

Installation of drainage treatment plants

When selecting a drainage treatment plant, first of all, water and soil conditions should be taken into account. At high groundwater levels, the treated sewage cannot be drained. The septic tanks have a standard inlet / outlet. Depending on the foundation depth of the tanks, it is possible to add a superstructure of different heights. Installation of tanks should be carried out in accordance with the assembly instructions provided by the manufacturer.

Proper use of drainage treatment plants

The proper functioning of the sewage treatment plant requires biopreparations and "ecological" use habits that do not have a negative impact on the bacterial flora. You can read more about biopreparats here. All the necessary information on the proper installation, operation and maintenance of a household drainage sewage treatment plant is available in the article on operation of a drainage sewage treatment plant.
