The creation of a system of storm sewer dash and supply should always begin with the preliminary preparation of the project, both in private and in general construction construction. But the essence of the work of her communications does not change from this. With your own hands, a storm sewer created in his free from work will perform two main functions: remove accumulated rain water from the surface of the roof, as well as melting to water outside the borders of the residential area.

The calculation of the storm sewer should begin, taking into account the value of the average annual fluid flow, as a rule, this value lies on average between 50-100 cubic meters of melt and rainwater. If everything is in the narrow sense of the word “lower it to a gear”, and not to remove the liquid from the site, large puddles will accumulate in the courtyard, and in the winter period they will turn into slippery ice traps. During the period of the thaw, the soil will be oversaturated with moisture. Over time, the destruction of masonry at the house may be discovered due to the fact that around the foundation of the building constantly increased humidity and the foundation systematically gets wet.
The storm sewer device includes the following components:
Distribution funnels that provide uniform collection of arches from the surface of the roof of the structure
Filtering components in the form of sandy traders
Drainage system and collectors for transportation and uniform distribution of fluid through the site
Sumps and water drives with an increased fluid level in the system.
Nuances in storm sewers
External storm sewers have several characteristic features, which are no internal storm sewer, for example, rain channels isolated by waterproof cement, instead of the drainage system tubes, which often exclude the use of storage tanks. Also, the presence of sand traps is not so necessary due to the possibility of self-cleaning the system of removal of water flows.
Upon completion of the assembly of the storm sewer system, it would be nice to check the normal functioning of the system. As a test test of new-carved storm sewers, a “test” rain is made. In the order of the line, a bucket of liquid is poured into each water reception collector, and the same amount of liquid should be collected at the exit in the bucket. The intensity of the flow with which rain water will pass through the system will tell us whether the slopes are made correctly, and the speed with which the containers will be filled will talk about the absence of obvious leaks in the system. The stormy drainage system is excreted into roadside grooves, natural reservoirs or storage absorbing sumps.
