And our dear gardeners amateurs got the plot, but the thing: gryadochki smashed, trees planted, and the spring came - sailed beds, mowing trees ... I had to re-start the job: soil navezli, gryadochki corrected, treesEven - Eye rejoices!And again in the spring of twenty-five!

The reason lies in the waterlogged soil, in the valley uchastochek something is in zabolotistoy terrain, and because attempts to raise the level of the ground in vain.Where is the exit?- In the drainage system!

construction of drainage system should start in the summer, when the water table dropped low enough.

And so, we need: receiving water (river, stream, canal, ditch or ravine along the road, that is, any place where you can take water from the drained area), the conductive network (a system of open and closed channels of the collectors, through which water is transportedwith a drying area in the receiving water), regulating network (consisting of most drainage) and protecting the network (channels, intercepting surface wa

ter and groundwater, coming from neighboring territories located above).

now about how to make these things.

first determine the receiving water.It must be remembered that any site has a bias, even when it is not visible visually.If there there is a river, stream, lake, in 90% of cases of the 100% slope is towards the reservoir, and, consequently, to seek him, and all groundwater.In cases where the natural receiving water is not available, you can define the slope of the plot of water accumulation (eg, roadside ditches along the perimeter of the site, the level of water in wells in the county, according to the degree of soil siltation, etc.).

second, Running Water dehumidifying network.Pave trench under a closed manifold through which water will flow from the drains in the receiving water, and only then proceed to the trenches for drains.The width of the trenches for drains and sewers should be 35-40 cm, and the depth - 1 meter, the collector should be positioned below the drain so that water drains by gravity came from the sewers and from the reservoir - in the receiving water.

Third, regulating the network, ie, actually, drainage.In a small area (less than 50 acres) diameter collector and drains may be the same - 5-7 cm. The minimum drop height for drain defined in 2 cm for every 10 meters, and for the collector - 3 cm. To connect drains to the collector must be overlappedfixedly bonding wire, making 2-cm hole for the passage of water in the place where the drain collector and adjacent to each other.The distance between the drains can be 8-10 meters.

fourth, enclosing a network.It consists of a channel depth of 1-1.5 m and extends generally around a few gardens or on the perimeter of the garden community.The main task - to block the path of the surface ground water coming from upstream neighboring territories.

must be remembered that the drainage system should be located no closer than 0.5 meters from the fence and 1 meter from the blind area home.

In establishing drainage systems do not forget to take care of the preservation of topsoil.Before starting work, it is removed and at the end of their fertile layer is returned to the place, and if the dewatered area has not domesticated, the introduction of large amounts of organic fertilizer not only improves fertility, but also increase the rate of filtration - the soil becomes more friable and permeable.

This drainage system is primitively simple in its design and similar methods of controlling humidity in the active layer of the soil have long been used by our ancestors in the development of agrarian land zabolotistyh.Initially, as a drainage material used: twigs, gravel, sand, etc.But it's worth noting that this system has served our ancestors did not last long, for example, a layer of brushwood in the trenches 35h40 cm rot on average for 3-5 years.Drainage with gravel or other material at hand is only about 5-7 years, and then he drags fine particles of soil and clay, wash it, you know, it is impossible - only to be replaced.And over the drainage has beds, paths, gardens ....

Therefore, as a material, advise using special drainage pipes made of plastic.They are placed directly on the bottom of the excavated trench backfilled and the top 10 cm layer of gravel.Also, drainage pipes can be prepared and self: buy ordinary plastic pipe, drill drainage holes and wrap the filter material - dernitom.But in this case, the tube must be laid on a 5 cm layer of gravel to protect the weep holes from rapid sedimentation.

Proper use tubular drainage system involves flushing the drainage pipes from silting once every 2-3 years.For this purpose the water hose is connected to the open edge of the reservoir (that flows into the water intake) and hosed water drainage system is washed with about half an hour.

With proper care of the drainage system, it will last you at least 50 years is guaranteed!
