Storm sewerage in a private house with your own hands: planning and installation

Storm sewage in a private house with their own hands can be equipped with every home master. This system is designed to effectively drain meltwater and atmospheric precipitation. On the roof of the house, the area of which is 200 square meters, during the year approximately 100 cubic meters of water falls. On the site, this volume is even greater. Puddles can cause some inconvenience, but this can be called a trifle, if you compare with what kind of trouble brings the accumulation of a large amount of liquid.

Necessity of arrangement

Storm sewerage in a private house with their own hands, the construction of which is described below, prevents the absorption of water by soil, which could cause irreparable damage to the house, for example, to influence the subsidence of the basement. If water accumulates in large quantities on the site, it will destroy the landscape design, as on wet soil plants can die.

Planning

If there is a storm sewage system in the private house with your own hands, then you will have to design this system, which consists of filters, trays and pipes installed under the slope towards the sewerage. On the gutters the liquid will drain from the roof, entering the drainpipes, and then - into the collector. The discharge pipes can be laid underground or on the surface. Water can be collected in two ways: a point water intake or a linear one.

In order to remove water from the roof, the most commonly used point water headers, which consist of plastic funnels, connected by underground drainage pipes. The system is supplied with filters that clean it from leaves, grass and other debris. When designing it is important to take into account that the installation of the underground part of the sewage system should be carried out at a level where the soil does not freeze. If this is not possible, pipes should be insulated, for which the most common is polystyrene foam. Due to the presence of thermal insulation, the depth of the trench can be reduced to 60 centimeters. When determining the diameter of pipes, it is necessary to take into account the annual rate of precipitation in the territory and the area of the site. Most experts use pipes with a diameter of 110 millimeters. If the sewerage will pass in those places where the heaving ground predominates , it is possible to equip a sand cushion for collectors. This will eliminate the subsidence of the soil.

When backfilling, it is necessary to carry out layer-by-layer compaction of the soil, while the slope of the sewage pipes should be 1 cm per meter of the pipeline. When installing storm sewage in a private house with your own hands, do not connect the pipes at a right angle, as this can cause clogging of sewage and the accumulation of debris.

Design: Determine the depth of the channel bookmark

During installation, the channels, pipes and trays are laid to the depth recommended for a certain region. The exact value should be clarified by contacting the construction company. Thus, in the middle zone, rainwater drainage is laid to a depth of 0.3 meters, this applies to the case when the diameter of the pipeline does not exceed 50 centimeters, this parameter applies to open trays. When choosing pipes and trays with larger dimensions, the penetration should be made 0.7 meters. If you install rainwater drainage yourself in a private house with your own hands, it is important to take into account one important point, which is laying the system above drainage, if the latter is on site.

Precise rates of bias

If you purchased pipes with a diameter of 150 millimeters, the slope should be 0.008 millimeters per meter. When the cross section is increased to 200 millimeters, the slope should be 0.007 millimeters. Depending on the conditions of the site, the slopes of the pipes may vary. The maximum gradient is 0.02 millimeters, as for the channels and receiver attachment zones. This is due to the fact that at this point an increase in the speed of the gravity of the fluid is required.

Before the sand catchers, the flow velocity must be slowed down so that the suspended particles settle. Therefore, the angle of inclination in these places should be the smallest. Each domestic master can be equipped with storm sewage in a private house with his own hands. Planning in this case can be done independently. At this stage, it is important to take into account that devices for collecting liquid in envelope-type systems must be mounted at the intersection of slopes. In this case, we are talking about structures that are equipped with funnels-funnels.

Mounting

The implementation of stacking of storm showers can be compared with the installation of external sewerage systems of the pipeline. But if the house is not equipped with drains, it is necessary to begin work with their device. In the ceilings, it is necessary to make holes for the rainwater collectors, and after the installation is completed and fixed to the bituminous mastic, the junctions are well sealed. At the next stage, the master can proceed with the installation of drains and sewers. Each element is attached to the structure using clamps. Further trays are installed, if it is a linear system, or branch pipes, if it was decided to implement a point diagram.

Work on the underground part

Storm sewerage in a private house with their own hands, the slope of which was mentioned above, is arranged in the next stage in accordance with the norms in a certain region. According to calculations it is necessary to dig a trench, and if the pipeline will be warmed, then a shell of geotextile and crushed stone will be formed around it. You can lay a pillow of sand, well tamped the bottom. Large stones must be removed, pits formed - covered with soil. The standard thickness of the sand cushion should be 20 centimeters.

To install a collector tank, a pit is formed, and a plastic container can be used as a collector. If you wish, you can perform a collector well with your own hands, casting concrete into the pre-arranged formwork. Then the pipes are laid.

Recommendations of a specialist

Storm sewerage in a private house with your own hands, the construction of which can be performed by you in several stages, should contain manholes if the straight branches have a length of more than 10 meters. At the points of joining the pipeline and collectors, sand catchers must be installed. Devices and devices are connected in a single circuit, the docking points are well sealed.

Final work

Due to the fact that the cost of the work by the specialists is quite high, the house masters install a storm sewage system in a private house with their own hands. Carrying out the tests at the final stage you must implement, this will help to understand whether there are weaknesses in the system. Before the backfilling, tests are carried out by pouring water into the water receivers. Further, the system is filled with soil, and pallets, trays and gutters are equipped with grills. If your house has a pitched roofing system that does not have gutters on all sides, you should install the gutters with grilles in the required places, including these elements in the common network. Livnevka country house can be included in its own canalization, because the dangerous components that need a fine cleaning, it is not.

Conclusion

You will be able to save money if a storm sewer is installed in a private house with your own hands. The construction of systems of this type should not involve pooling with drainage. In this case, the structures will work inefficiently. Livnevka should function separately, if it overflows, it can cause the foundation to be washed, which will lead to devastating consequences. In order to ensure correct gradient, a rope rope should be used. Storm sewerage in a private house with their own hands, the rules of construction described in the article, will be mounted in several stages, one of which provides for the fastening of trays, which can be done with cement mortar.
