Do-it-yourself drain pit in the garden
A wastewater collection system, functioning autonomously indispensable solution for the lucky owners of private homes and household plots, where there can be no question of organizing a centralized sewage system. That is why, organizing the discharge of sewage to the summer cottage, the majority seek to give preference to this method of water disposal, since it is the simplest both in execution and in maintenance. According to experts, the choice in favor of this method of arranging the discharge of sewage will be most optimal if the work is planned to be carried out on their own, without the involvement of specialists.

DIY drain pit: the main stages of construction
The principle of the functioning of the drain pit is based on the accumulation of wastewater in the settling tank, which needs constant cleaning, the frequency of which is directly determined by the amount of wastewater, and precisely the number of households living in the house, and the availability of household appliances that determine the amount of water consumption.
DIY construction of a drainage pit involves several stages, each of which carries its own functional load and should not be missed. What are these stages?
1.Determination of the location of the future structure and its volume;
2. Selection of material for construction work;
3. The direct stage of construction and the progress of land work;
4. Arrangement of the territory adjacent to the construction, which subsequently will provide an unhindered access of special equipment.
Territory Selection: Key Aspects
If you set a clear goal to find the answer to the question: How to make a drain pit in the house ?, according to experts, first of all determine its volume and location. In most cases, it is equipped as far as possible from a residential building, since its design features do not guarantee a complete absence of an unpleasant odor. The dimensions of the sewer pit depend on the time spent on the territory of the summer cottage and, accordingly, the intensity of operation of the residential facility. If the residential building in the country house is the place of constant residence of all family members, then the volume of the tank is calculated on an impressive amount of wastewater, but if the residential facility is used only in the summer or as a place to spend a weekend in nature, the dimensions of the drain pit can be much smaller.
When choosing the location of the drain pit, you should pay attention to a number of aspects that are fundamental in choosing the territory for construction:
1. Groundwater level: the location of the drain pit should be in the place where the groundwater level is at least two or two and a half meters;
2. The location of wells or places of water intake: ideally, the drain pit should be located as far as possible from such structures, namely at a distance of at least 30 meters;
3. The length of the pipeline is crucial when choosing the location of the pit, since it is not recommended to equip an excessively long pipeline, which will complicate the maintenance of the drain pit;
4. The possibility of an unobstructed access, which is necessary for periodic cleaning of the drain pit.
Material for a drain hole. What to prefer?
The choice of finishing material for the arrangement of the drain pit is an equally important stage of its construction.
Previously, wall lining was carried out using wooden boards and red brick, however, at the stage of modern construction these materials are used less often, but despite this, they can be considered as one of the construction options.
By equipping a drainage hole made of brick, the masonry is staggered, as this will allow sewage to seep through the formed openings into the ground without hindrance.
At the same time, it is recommended to pour crushed stone or broken brick around the brick, which will further accelerate the absorption of moisture. Arrangement of a drain pit from tires is another method that has found wide application, but the modern variety of materials used in the process of arranging drain pits contributes to the increasingly rare use of automobile tires in the construction of drain pits.
At the moment, the most popular among consumers is the method of arranging drain pits, which involves the use of reinforced concrete rings, which can significantly reduce the time to organize a drain pit in the house.
Arrangement of a drain pit: sequence of work
Answering the question: How to make a drain hole? we’ll clarify that any construction of a sewer system begins with land work, the result of which is the arrangement of a settling tank.
At this stage, it is recommended to resort to the help of an excavator, however, it is worth noting that this method can cause a violation of landscape landscaping of the territory, and if a large number of garden and decorative trees grow on your site, land work can be done manually.
At the same time, the depth of the shaft should be at least 4 meters, taking into account, including a drainage pillow, equipped at the bottom. It is not recommended to exceed the indicated depth, since a tank that is too deep will be difficult to clean.
Regarding the shape of the drain pit, it is important to note that cylindrical will be most preferable, as this will facilitate the cleaning of the tank.
As often only sealed cesspools are allowed to be built in residential villages, land work must be completed by concreting the bottom, by first making a qualitative compaction of the bottom, and then pouring concrete mortar made from cement, gravel and sand.
If you plan to build a drain pit equipped with a filtration function, a layer of sand and then crushed stone are successively laid on the bottom of the tank.
At the next stage of construction, brick walls are laid out. In this case, experts advise using a ceramic brick that is resistant to moisture.
In the case of constructing a drainage pit with a filtering function, the brickwork is organized in such a way that there is at least 5 cm wide space between the rows of masonry, if you plan to build a sealed pit, wall covering is completed with an additional coating of concrete mortar, which eliminates the possibility of water leakage. Another important point in arranging the walls of the tank is filling the space between the walls of the pit and the pit. For the filter pit, sand and gravel will become such a material, and for tight clay.
The know-how of modern construction is the organization of a drain pit using reinforced concrete rings. Since in this case the masonry stage is excluded, the construction process is significantly accelerated, however, the impressive weight of the rings often makes them abandon their use.
Drain pit from the rings. Arrangement principle
The installation of the drain pit is carried out in several stages, the first of which is digging a pit with a depth of one meter and a diameter corresponding to the diameter of the ring. Using lifting equipment, the first ring is lowered into it and coated with concrete mortar from above. Subsequently, the next ring is installed on it and so on until a drain hole of the required depth is built. A concrete cover is placed on the upper ring.
The result will be a kind of structure resembling a tower, which must be lowered down. To do this, one person sinks to the bottom of the pit and begins to extract the soil, and the second takes buckets with the extracted soil. If you plan to do this manually, take care of having an assistant.
Sealing the bottom of the tank, as well as the joints between the rings is carried out using cement mortar, as well as bitumen.
If the pit was settled on the site. It is necessary to take care of convenient access for sewage machines. In this case, it is not necessary to pave the road, but the passage should be indicated quite clearly.
