Storm drainage to avoid puddles
On most suburban areas, landowners try to organize a drainage system, especially in cases where there is a danger of flooding the foundation with underground aquifers. But do not lose sight of the precipitation, especially plentifully falling on the ground in autumn and spring.
Autumn showers can irrigate the land for several days in a row, turning the fertile layer into a swamp. A spring thaw with subsequent thunderstorms accompanied by rains threatens with serious trouble the roots of plants, the foundation and may well disturb the stable operation of the sewage system.
This is why, along with deep drainage, it will be useful to lay drainage drainage, which quickly and efficiently directs surplus moisture from the surface to the nearest collector. In this case, is extremely undesirable to combine two completely different systems, ground and stormwater, since the latter will overload the first , and as a result, water will flow back to the surface through the branch pipes.
It is best to lay the storm sewer in the same ditches, in which the domestic runoff will be laid. To collect excess moisture on the site, point and linear water headers are placed, in the areas with particularly abundant precipitation, door pallets are installed. All this economy is connected in a single system by special corrugated PVC pipes - drains.
From the flooding, the basement will be saved by the correct drainage of groundwater
In addition to the fact that downpours and melting snow oversaturate the surface of the soil, leading to its waterlogging, they affect the groundwater level, especially when turbulent streams rush into rivers and leave the banks. Even if your home is far from the riverbed, rest assured that underground waters rise with the level in the river, and if you do not have groundwater drainage on the site, a set of problems standard for such situations may arise.
What is a deep drainage system? First of all, these are special pipes that not only do not have to be sealed, but on the contrary they have a surface with the smallest holes through which moisture enters from the surrounding soil. To get moisture from the soil to the drains better, pipes are laid in a layer of gravel, which serves simultaneously as a pillow, protecting against possible damages of .
The drainage slope for groundwater drainage should be standard - not too large, so as not to end up digging the Grand Canyon in the end, but not close to the absolute horizontal, because then the outflow of moisture will be somewhat difficult. The optimal option is recommended for any drain 5-10 millimeters per meter.
At the end of the entire drain system, a collector is installed from which the discharge is discharged either outside the site, into the nearest ravine, or into the central sewer. If necessary, a pump can be installed in the collector well for more rapid pumping of the water accumulated in it. Such measures are necessary in the event that the area of the site is large and the well fills faster than it should.
How best to design drainage of water?
So, somewhere among the flowerbeds and under the garden beds there is deep drainage, how to lay such pipes is a separate story, let's just say that first of all they must cover the house along the perimeter, being buried deeper than the basement. The same applies to household buildings with cellars, in the garden, conduct drains the way you prefer. But the drainage of surface water requires proper planning.
Above we have already talked about point and line gutters, now it's time to explain their purpose and location. Point water headers are usually located where separate streams of life-giving moisture drain from roofs and other surfaces, gathering in one jet, through a chute or a pipe.
Linear drains are laid as ordinary shallow ditches along tracks made with a bias toward such a collection of excess moisture. The only thing that distinguishes such elements of storm sewers from ordinary ditches is special concrete, metal or plastic gutters, covered with gratings.
All gutter elements are connected to pipes with a diameter of 110 millimeters by special clutch-drums.
Digging trenches around the house, and in those places where the drainpipes are located on the walls, just under their outlets make small extensions, so that a pitcher canister is placed in the pit. In a container of rectangular shape, a sand catcher is usually placed, the task of which is not to let small debris into the drain system. On top of the box is covered with bars.
To a special outlet nozzle, drainage is installed, drainage for this purpose is intended. In certain places, pipe couplings are installed on pipes to connect pipes from linear waste elements, located, as already mentioned, near the tracks and sites of the site. Another pipe joins the vestibule, also having, as a rule, an outlet. The entire system is directed to the collector with the necessary inclination, to which the drain drains from the deep drainage.
