The stage preceding the installation of the installation of autonomous sewage system is just the same design, in which the development of the necessary documentation (technical and design) is carried out, calculations of a technical, as well as an economic nature are made. Design begins with the definition of the number of people that will be in the target building.
The next important aspect, which is extremely important to read during the design of the system, is soil. So, autonomous sewage can be installed on any type of soil, and the need for waterproofing completely disappears. In addition, in this case, you will not need and cement the site under the pit. The stability of the entire system does not depend on the temperature value. Sandy soils tend to positively affect the filtering of the natural type. In order to competently draw up the entire project, as well as make the choice of the right treatment equipment, it is necessary to have the following information: the number of residents, the level of water span, the execution of drainage, the value of the depth of the output pipe, as well as the characteristics of the equipment used.
