It is quite simple to arrange a storm drainage system on your own. However, for its effective operation, it will be necessary to calculate the throughput. If you carry out these works correctly, then stormwater will be able to save you from the many inconveniences expressed in the malfunction of rainwater flow. Among other things, with the help of this system you can make any design more durable. Here we are talking about pavements, foundations that deteriorate due to leaching of soil.
System classification by sedimentation method
Storm sewage can be of open type, while water will be discharged using gutters outside the site. Trays can be buried, as well as fixed or installed in the tracks. The open type system is most often used in small areas, as well as in small towns, where the population density is relatively low.
If you are interested in "Superstroy" storm drainage systems, then you can equip a closed sewage system, which involves a deep drainage system. At the same time, rain is collected by built-in trays, as well as sand traps. Through the pipes, the liquid enters the storm wells, and then with the help of pumping equipment it is sent to the sewage network. After the sewer collector, the liquid enters the thalwegs, and then to the treatment facilities, and then to the artificial reservoirs.
If you decide to choose a mixed type system, you will need to install not only the trays on the street, but also mount the pipes underground. In this design, the drainage is carried out by gravity, except in cases where the conditions are not so favorable. These may be uneven terrain.
The network route is laid at the shortest distance to the collector and then to the reservoir. In this case, pressure-free pipes based on reinforced concrete should be used. This option is suitable for reducing construction costs.
For reference
In addition to the linear method of collecting rainwater, you can select envelope, which is more complex. But it is preferable to drain the liquid by a linear method - this is exactly the case when a simpler design is better.
Specialist advice
If you will be equipped with stormwater drainage systems, it is highly undesirable to combine them with drainage, since in general the system will work inefficiently. Stormwater must work separately, its overflow can cause undermining of the foundation, which will lead to devastating consequences.
Installation of the roofing system
After the necessary calculations have been carried out, you can begin installation work. Pipes that drain fluid from the roof must have a slope of 2% with respect to the length. This parameter should not be made more impressive.
Installation technology involves the following manipulations. The master will have to install storm water inlets. For them, holes should be made in which the receivers are fixed using bitumen mastic. After the waterproofing of the existing joints is carried out. If you will be installing stormwater drainage systems, you should decide whether they will be point or linear. Depending on this, it will be necessary to suspend the pipe or receiving trays.
The next step is the installation of drainpipes for risers or a storm drainage system. It will be necessary to provide a closed spillway to the collector. Storm drainage can act as a receiver if the spillway is open. The drainage must have a chute type.
Storm sewage systems involve installation, which is carried out using clamps. The latter are fixed on floors or walls. In advance, you should be marking, while the master should take into account the angle of inclination, which is mandatory.
Work on the land part of the drainage system
When storm drainage systems are equipped, there is a need for installation of the ground part. At the same time, installation requires compliance with a certain technology. The sequence of work involves ensuring the correct slope, for which a tracing cable should be used. As soon as the marking has been carried out, it will be necessary to carry out earthwork. To do this, the master must prepare a trench and wells, taking into account the depth of freezing. You should dig the grooves into which the ground trays will be mounted. At the next stage, ground-based storm water inlets are installed. Trenches should be well prepared, for this a layer of sand is laid out at the bottom, which is then carefully rammed.
Features of the work
Stormwater drainage systems, the photos of which you can consider in the article, provide for the presence of pipes and trays, which are laid in the next stage on the places provided for these elements. You should combine the elements of the sewage system, sand traps, storm water inlets and wells into one system. At the final stage, the trays are fixed with cement mortar. The grilles are being installed, and after that the pipelines can be closed.
The surface storm drainage system must be tested, for this the master must carry out a test spill. On this we can assume that the arrangement is completed. Such a system will be ready to serve for many years, but this statement will be true only if you operate the system correctly.
Arrangement of a drainage system
Installation of drainage systems provides for the presence of a drainage system. If we are talking about point drainage, then you need to use local drainage systems, namely wells and storm water inlets. With their help, it will be possible to collect liquid from one site, this may concern, for example, the roof of a house. Installation is made under a drainpipe or irrigation taps. These elements must contain grids, which are complemented by a filter basket. The latter will serve to detain the garbage that is sometimes brought in for water. Drainage is connected to the underground sewer pipes, this will eliminate the storm water flow into the well.
Do-it-yourself rainwater drainage system can be equipped and supplemented by storm linear drainage. This part of the system is necessary for collecting precipitation from a significant area. Using this component, it is possible to solve the problem of water diversion in a comprehensive manner. The master can use a linear drainage system, namely channels, trays and gutters. Inside the sand trap there should be a basket in which trash accumulates. Sewerage cleaning should begin by emptying these baskets.
Nuances of installation work
If you will be equipped with storm water drainage systems in the country, then you must follow certain rules. Initially, marking is carried out, and pipes are also prepared. Most often, the latter are made of PVC, and their diameter is 110 millimeters. The elements are interconnected by means of a double coupling. Replace the pillow, which is laid on the bottom of the trench, with crushed stone, the thickness of this layer should be 8 centimeters, after which pipes are laid for such preparation. Then the ground should be backfilled, each layer must be well tamped. Attention should be paid to the fact that under the drain pipe the system must be installed vertically.
