Owners of suburban areas with high groundwater levels usually experience difficulties with the arrangement of autonomous sewerage and drains. In wetlands, cesspools quickly fill with sewage, and the cost of sewerage maintenance becomes quite high. But it is possible to install an effective septic tank at a high groundwater level if the owner of the site is ready to increase the volume of construction and incur additional costs for the purchase of a ready-made installation. The investment of additional funds will subsequently pay off in the impeccable operation of the sewerage system and the absence of problems with its maintenance.
Criteria for choosing a septic tank for an area with a high groundwater level
It is difficult to answer this question unambiguously, because... In addition to the water supply system, the advantages and disadvantages of each type of autonomous sewage system, several more factors influence the choice:
- frequency of residence;
- relief of the site;
- number of users (residents);
- type of soil, its filtering properties;
- the presence of wells and boreholes nearby.
In any case, the structure must be completely sealed and resistant to water pressure and soil pressure.
Let's take a closer look at the pros and cons of each type of sewage system:
- Biological treatment stations
- Ordinary storage tanks (analogous to a cesspool)
- Non-volatile septic tanks
Schemes and drawings
When starting to arrange this important engineering system, first of all it is necessary to draw up a diagram, at least in the form of a sketch. This will facilitate the installation of the system, allow you to determine the amount of materials needed and draw up an approximate estimate.
A typical internal sewerage layout for a two-story house is shown below.
Typical sewerage scheme
Designations:
- A – central riser;
- B – Hole for ventilation;
- C – toilet sink;
- D – storage tank for draining;
- E – washbasin sink;
- F – siphon;
- G – bath;
- H – pipe inclination angle.
If necessary, you can make a connection drawing for a specific room, for example a toilet.
SBO - biological treatment stations
SGBO design
The most technologically advanced, convenient solution for installing an autonomous sewer system in a private house, cottage or country house. Effluents are purified up to 98% with proper operation. There is no need for the costly construction of drainage wells or filtration fields, which take up free space on the site.
The cost of such treatment systems is higher, but it is completely offset by reliability and ease of use. The operation of the station (compressors, airlifts, pumps) requires a stable power supply and a regular supply of wastewater for the life of bacteria. But the purified water at the outlet can be used for technical needs.
