Waste disposal is one of the most important problems that the owners of suburban cottages, cottages and private houses regularly face. A common solution is the arrangement of a cesspool. But it needs to be constantly emptying, which entails additional difficulties. A good replacement can be a septic tank or a bioseptic AK4-7. This is a universal and functional treatment structure. However, a wide variety of types and modifications of septic tanks make their choice and acquisition quite difficult.
The main criteria
To make the right choice, you need to take into account some of the most important factors.
Firstly, this is volume. The optimal value is determined depending on the number of people who will regularly use the sewer. An two hundred liters are taken by about one person per day. This value must be multiplied by the number of people living in the house. In accordance with the requirements of SNiP, the septic tank is obliged to accommodate a three -day scope. Thus, the resulting value must be multiplied by another 3. All this allows you to calculate the optimal volume of septic tank without any problems.
Secondly, material. To create septic tanks, three types of containers are often used:
Concrete. This design is considered quite simple and durable. She is not corroded. Its main drawback is an impressive weight. Installation of such a structure is performed in several ways. Firstly, the installation of finished parts (special equipment is used). Secondly, pouring concrete in the finished formwork.
Plastic. Light design, favorably characterized by ease of installation. The duration of their operation is impressive and is at least 40-50 years. For installation, you do not need to use special equipment. It is worth noting that the ease of such a septic tank is sometimes its weak quality. The fact is that he can trite “surfacing” to the surface. To prevent this, the septic tank is concreted during the installation process or use a special “anchor”.
Metal. Such structures have a relatively low weight, which greatly simplifies their installation. In addition, they differ in relatively low cost, which ensures their high popularity. The only drawback is the tendency to corrosion, which significantly reduces the period of operation.
