If you decide to equip a storage septic tank in a suburban area or on the territory of a private house, it is important to initially carry out preparatory work. It is necessary to decide what material will be the basis of the system. The most common today are plastic or concrete cesspools. Among other things, it is necessary to take into account the rules for the location of this structure. The storage septic tank should be located at a distance of 5 meters from residential buildings. If there are wells or similar structures on the territory, then the capacity from them must be removed by 30 meters. If groundwater is high , then it will be necessary to install a treatment plant above the surface of the earth without immersing it in the ground. The owners must provide access roads to the pit, as it will have to be pumped out systematically. In order to ensure good sewage passage through the pipes, it is necessary to arrange the storage tank so that the pipeline approaches it along a straight path or has a minimum number of turns.
Features of preparation
If you are going to equip a storage septic tank, then you need to determine at what height the pipeline entrance to the treatment tank will be located. After that it is necessary to prepare a trench for pipes and a foundation pit for a drive. If the pipes will be located underground, then they need to be deepened by 1 meter, while 20 cm will go to the preparation of gravel and sand. This is necessary so that during the onset of frost the water that is located inside does not freeze. This will ensure the integrity of the pipes, otherwise there may be an obstacle to the outflow of sewage. If you place the pipeline on the surface of the earth, then this problem does not cease to be relevant. This problem can be partially solved by isolating the system with special materials.
Work on installing a storage tank made of reinforced concrete rings
The storage septic tank can be equipped with concrete rings. When preparing the pit, it is necessary to carry out earthwork so that the walls of the tank are one meter away from the walls of the pit. This distance provides access to the structure around the perimeter. The bottom must be well leveled; alignment with a cement screed is the best option. A concrete ring is mounted on the surface, which has a bottom. In the upper part there should be support ledges. At the next stage, the second element is mounted, which is a concrete ring with protrusions for the hatch on the upper part. Rubber should be used as a sealant. The storage septic tank assumes the presence of a pipeline, for it using a punch in the lower ring, two holes must be made. One of them will be intended for air intake. Now you can mount a pipe for the exit of gases, as well as install a sewer. The resulting joints should be repaired with a solution. After the entire surface has dried, it should be treated with liquid glass.
Recommendations for arranging a cesspool of concrete rings
If you decide to equip a storage septic tank for a summer residence, then for this you can use reinforced concrete rings. To begin with, it is important to determine how many people will constantly use the system. The basis is taken one cubic meter per person. Thus, for a family of 3 people, 12 cubic meters of storage septic tank will be enough. At the same time, natural needs are taken into account and it is assumed that a washing machine will be in the house. It will be necessary to clean such a system about 2 times a year.
When storage septic tanks are equipped, containers can be selected from different materials. Installation of drain pipes must be laid back during the construction of the house. If the building is quite old, and the sewage system is not provided for in it, then the pipes are laid to a depth of 80 cm, and it is important to observe the slope. Finally, the pipes must be removed at the last stage. Determining the rings for the sewage system, it is preferable to purchase factory-made products. It is not recommended to use those that were already in operation. During this time, they could lose their tightness. In the process of installing reinforced concrete rings, you can not do without special lifting equipment. This is one of the minuses of using such rings. After all, the rental of equipment will entail additional costs.
Nuances during the work
Fiberglass septic tanks are, of course, considered a more modern option. However, not all of them are satisfied for some reason. If you decide to prefer reinforced concrete rings, then the bottom of the pit must be properly equipped, only in this way you will eliminate the harmful effects of sewage on the environment. For 4 parts of sand, one part of cement and gravel should be used, the last of which is used in an amount of 6 parts. From these ingredients a solution is prepared in which water is gradually added.
Installation of a storage pit made of plastic
Recently, storage septic tanks are increasingly being equipped with plastic containers. Such popularity of this material is due to the ease of installation. However, such a system has a significant drawback. It is expressed in the fact that the capacity cannot be completely hidden underground.
Installation Features
Septic tanks made of plastic are equipped according to a technology that involves the preparation of a foundation pit, its walls should be 30 cm from the tank. The tank is installed on a level surface that is covered with a sand cushion or concrete screed. The container must be equipped with additional elements such as a ventilation pipe, as well as a float that acts as a beacon. This element is necessary for signaling that the tank is full. After the tank is installed on the site, you need to fix it. Inside, pour clean water to a height of 15 cm, but no more. Outside it is necessary to carry out the fastening of the supporting platform using a solution that consists of cement and sand. It is strictly forbidden to exert any load on the surface of the tank. It is strictly forbidden to fill the tank with earth. Although storage plastic septic tanks cannot be hidden under the surface of the earth, they are becoming more and more relevant for country houses. This is mainly due to the fact that products of this type are absolutely tight, which is confirmed by comparison with concrete storage devices. They serve much longer, which is why they justify their value in a short time.
Features of fiberglass storage cleaning systems
On sale today you can find fiberglass storage septic tanks. In their production, unsaturated polyester resins are used. This increases the reliability of containers. The manufacturer guarantees the life of the fiberglass tanks for 50 years. Such products are specially designed for use in the Russian climate, this indicates that fiberglass is resistant to external influences. Septic storage plastic, like fiberglass, is very convenient to mount for the reason that they have low weight, and at the same time they are characterized by high strength. Installation does not involve waterproofing or caisson manipulations.
Conclusion
The most often recently used fiberglass storage septic tank. The high groundwater level allows the use of only such treatment systems. That is why, before starting work, it is necessary to carry out geological studies.
