How to lay sewer pipes in a private house during

For a comfortable stay in a private house, it must be equipped with all the necessary engineering communications, therefore, in its construction, one of the most crucial tasks is the competent equipment for individual sewage systems.

Independent laying of sewage pipes in a private house, in most cases is performed on the same principle, regardless of whether an autonomous wastewater treatment system is installed at the site, or the house has a direct connection to the central sewer.

Features laying sewer network

In order to study in detail the features of the performance of such work, this article will discuss the main aspects of the arrangement of the system for collecting and discharging wastewater in urban and suburban private houses.

Also here will be presented a detailed manual, which details the main technological stages of the installation and connection of the sewer system.

Wastewater collection and disposal

In order to properly plan the sewage system for a private house, you need to think in advance about the place and method of disposal of domestic wastewater.

Currently, in individual housing construction, three types of systems are most often used for the disposal, processing and storage of liquid household waste.

1. The cesspool is a hermetic accumulative tank of considerable size, which is installed underground in the lowest place, in a remote area of ​​the local area. Such a device requires regular cleaning using an aspenser vacuum machine, so the price of its maintenance depends on the regularity of use and the average daily water consumption in the house.
2. The septic tank is an autonomous treatment plant, which is able not only to accumulate, but also completely process domestic sewage, giving at the outlet clarified water suitable for infiltration into the soil or watering garden plants.. With proper installation with their own hands, such installation during operation practically does not require additional maintenance.
3. The centralized sewage system is most often used in houses located within the city, town or other large settlement.. In this case, household waste is discharged into a common drain collector belonging to the city central sewage system.

   Tip! The best option for an individual country house is considered to be a fully autonomous two or three-chamber septic tank.

Laying of the external pipeline

All works on the arrangement of engineering communications need to start from the lowest point, and finish the installation and connection of household plumbing appliances inside the house. For this reason, regardless of the chosen method of wastewater disposal, the installation of a domestic sewage system should begin with the installation of a septic tank and laying of an underground pipeline.

For this, it is best to use pipes made of polymeric material with an outer diameter of at least 110 mm intended for outdoor use.

1. Having decided on the type and place of installation of the sewage treatment plant, you need to dig a pit of required size, after which, according to the technical project, install an autonomous septic tank or storage tank in it so that the inlet is located below the depth of soil freezing.
2. From the inlet of the sewage plant to the point of entry of the pipeline into the house, dig a trench, the depth of which should be 200-300 mm greater than the maximum depth of soil freezing for the region.

1. When installing a septic tank and digging a trench, it should be remembered that laying of sewage pipes in a private house should be done in such a way as to ensure the natural slope of the pipeline towards the sewage treatment plant not less than 20 mm vertically per meter of horizontal pipe section.
2. The soil at the bottom of the trench should be cleaned of large stones, compacted and poured a sand pad at least 100 mm thick.
3. From plastic pipes, fittings and fittings to assemble the sewer pipeline, trying to avoid bending horizontally at an angle of less than 135 °. At the point of each bend, install a revision well with a tight-fitting hatch cover that overlooks the ground surface.
4. Put the assembled pipeline on a sand cushion, sprinkle it with sand to the upper level, and then backfill the trench. In regions with a cold climate, before backfilling it is necessary to perform the insulation of a sewer pipe in a private house with the help of expanded clay or coal slag.

   Tip! When connecting to a centralized sewage system, for laying pipes, it is necessary to dig a trench of the required depth to the distribution well installed above the common drainage collector, after having previously coordinated work with the city utilities.

Installation of the house sewerage

All sewage systems inside a private house are mounted and connected according to the same principle as in a residential apartment, however, you need to think in advance about how to heat sewer pipes in a private house in the case of engineering communications in an unheated room.

1. Given the low location of the dwelling, it is imperative to install a check valve at the exit of the house in the system. This will help protect the premises from the ingress of sewage in the event of a return stroke during prolonged rains, spring floods or seasonal changes in the groundwater level.

1. By means of a socket connection, a common drain header is connected to the inlet of the check valve using a 110 mm diameter pipe, from which further wiring of sewage pipes in a private house is performed to all other sanitary devices.
2. If there is a bathroom, a washbasin or a bathroom on the second or third floor of a private house, a common vertical riser made of a 110 mm plastic pipe, which should end on the roof of the house with an air vent with a check valve, is connected to the drain manifold.
3. All sanitary appliances on the floor are connected to a vertical riser using plastic sewer pipes with a socket connection. To connect the toilet, pipes with a diameter of 110 mm are used, and for all other devices - 50 mm.

   Tip! To facilitate cleaning and prevent unpleasant odor in the room, each plumbing fixture should be equipped with a siphon with a water seal.

Conclusion

After reading this article, it becomes clear that it is quite within the power of any home craftsman to equip a sewage system, both in an urban and in a suburban private house.
