Accumulating water on the site can cause some inconvenience to residents. If this happened to you, this indicates the need to install storm sewers. It will consist of storm water inlets, pipes, trays and wells.
What is storm water drainage?
If you wondered what it is - a storm shower, then you should know that it is a system where water is collected for subsequent withdrawal. If such a design will be installed on the site, then it must be placed around the perimeter of the house. As a result, it will be possible to obtain a whole network of branches that will collect, filter and store water.
If there is no rainfall on the site, then precipitation will flow to the house, destroying the foundation and the adjacent area over time. When wondering what it is - a storm shower, you should know that it has a standard scheme, which is quite simple. Channels can be located above the ground or under the ground, they intersect each other in several places, and these points are called catchment areas.
The design of the storm must be carried out together with the drainage system. These structures are laid at the same time. Elements will be located in parallel, this is true if the foundation of the building is laid too deep.
Sewage for sewage can be classified by installation methods. Water may enter the drain pipe. However, the system near the foundation must be mounted without errors, it is important to choose pipes, the cross section of which will be able to undergo the assigned loads.
The main advantage of installing a drainage system is the cost-effectiveness of components. However, water will splash and fall onto the walls of the house. You should be prepared for the siltation of the drainage pipe to occur about 3 times faster.
Thinking about the question of what it is - a storm shower, you should also pay attention to the consistent design of the outer trays. This scheme is quite common, but can freeze when the temperature drops. Sometimes in spring an ice crust forms on the blind area. The main advantage of a shower arranged according to this technique is the ease of installation.
The third method is the installation of storm water inlets located under the roof drain. The pipes are connected in a single chain, which is located in the ground. The fluid is discharged off-site, which reduces the degree of load on the drainage system, which remains unoccupied. This storm storm fits better into the exterior of the site and does not damage the landscape.
How to make a shower yourself
After you figure out what it is - a storm shower, you can begin to equip it. Work begins with the preparation of the scheme, which is necessary to calculate the material and its acquisition in the right amount. It is important to determine how many risers are in the drain from the roof. The number of storm water inlets will depend on this value.
You can determine the length of the pipe taking into account the size of the perimeter of the house. At this stage, you must determine the depth of the system. If you plan to use it all year round, then the depth should be below the freezing line of the soil. The superficial laying scheme is suitable for the storm shower, which will be used only in the warm season. A rain storm device may provide for the installation of a heating system on the roof, which will ensure ice melting in the cold season. The system will need to be deepened by 1.5 m.
Before you make a shower storm with your own hands, you must mark and dig a trench for pipes. Depth is determined taking into account each region individually and depends on the level of soil freezing. The trench should be positioned a maximum of 50 cm lower with respect to the freezing line. These centimeters will be needed for the installation of pipes and the installation of a sand cushion.
The width of the trench will depend on the cross section of the pipes and should be 15 cm larger, which will simplify the laying of sand cushions. If you plan to arrange a rain shower with your own hands, and there is no way to dig a trench of the required depth, it is recommended to lay the pipes and insulate them with special material.
The diameter of the products should be 100 mm or more, but in the latter case, the trench should be wider and deeper. Stormwater will work on the principle of gravity, so it is important to ensure a slope of 2 cm per meter. If you are thinking about how to make a storm, you should also take care of the presence of inspection wells, the number of which is determined by the number of bends and branches. They are covered with thermal insulation and supplemented with special hatches.
If the step from the gutter or collector to the house exceeds 10 m, then the transition must be supplemented by a viewing well. If it is planned to use rainwater for domestic purposes and bring it to the site, then the sewage system is made in such a way that the initial accumulation is in the collector.
Installation of stormwater may not include the installation of inspection wells. In this case, holes must be cut in the pipe through which a certain amount of liquid from the system will go into the soil. However, it will not be possible to clean the system. The fastening of the pipes together should be carried out with maximum tightness, for this the seams are treated with waterproof glue or sealant.
When the collector and pipes are laid, it is necessary to install a vertical drain, which should be directed to the place where water will accumulate. The drain is connected to the storm water inlets, which are also called rain funnels. You need to set them slightly below the main level of the track. The storm water inlet is placed so that water from the roof gets to it.
The definition of rainfall was presented above, however, it will not allow to understand with what sequence to carry out the work. Therefore, before they begin, you must familiarize yourself with the technology. There are roofs where the storm water inlet is located only on one of the sides, in this case it is not directly possible to connect the sewer to the funnel. Under these conditions, a guide bend is installed. It is necessary to divert water to the drain.
Such constructions are supplemented by gutters, on which water flows to the side where there is a drain. The trays and the water collector should be deepened by 60 cm. The water will not come in very clean, therefore, sand traps should be installed in the system, which should be located from the drain pipe to the receiving trays. These elements are the same trays, but with special grilles.
Before the line of entry into the garage and the porch, it is necessary to perform door systems, they will act as water intake trays. From above they are covered with plastic or iron gratings. Sewage sewage is not recommended to be buried immediately after installation. A trial run is recommended.
To do this, pour a bucket of water into the stormwater shower and see if the pipes pass the liquid, and whether gravity flows correctly. Especially carefully should check the places where the pipes were connected to the trays and storm water inlets at the base of the house.
If you yourself are unable to carry out the installation of a storm shower, then you should contact the specialists. They offer the buyer installation with and without material. The design of the system will cost the consumer about 1100 rubles. per linear meter. But further work will differ among themselves in cost, which is affected by the use by the contractor of his material.
Cost of work
Installation of sewage with material will cost from 1800 rubles. per linear meter. If you yourself will acquire the material, then the services of specialists will cost 1200 rubles. per linear meter. In this case, we are talking about deepening the system by 1 m. If pipe insulation is added to the work, then the price rises to 2100 rubles. per linear meter. When the material is not purchased by the contractor, the price drops to 1700 rubles. per linear meter. If you need to increase the depth of the storm you will have to pay 3,100 rubles. and 2500 rubles. per linear meter, respectively.
The basic scheme of storm sewers provides for the presence of drainpipes and those that lead to collectors, as well as storm water inlets. The system has wells of a point catchment, funnels, troughs and a special system of trays. Before starting installation work, it is important to take care of the presence of additional elements in the form of siphons, sand traps and plugs. The latter are necessary to prevent the return of water in the opposite direction.
