How to make the right drainage garden plot

Often after the snow melt or after a heavy rain moisture is long is not absorbed into the soil, at their summer cottage there are puddles, water can even rot. If the site is located in the lowlands, the plants feel depressed, grow weak, quickly lose their decorative qualities. To prevent waterlogging of the site required high-quality drainage system. The meaning of the drainage system is to ensure the favourable condition of the top soil layer at a depth of 1-1. 5 meters by water drainage from ground level.

The drainage system of the garden plot may be open or closed. Open type allows drainage of rain and melt water; closed - removes moisture already absorbed into the soil. It should be noted that the combination of open and closed drainage gives the best results.

Outdoor drainage area of an open type is a group of shallow and wide ditches dug at an angle; the water flows through them and freely gets on the ground outside of your site. An integral part of the drainage system of this type is the recipient. The recipient can be a natural river or a ravine; but if the relief does not give such possibility, it is necessary to build it. The drain hole will be a great tank, capable of holding excess moisture. The only thing to consider is the need to periodically pump water from the water intake.





Water from the inlet can be used, for example, for irrigating land or in the system of flushing at their summer cottage. If you have installed additional filtration system, melt and rain water can be used for washing dishes and for Laundry.

The principle of operation of the drainage system of the closed type is a little different from the system of open type: the main difference is that located on the surface area of the grooves pass under the ground at a depth of 0.6 to 1.5 meters. On the appearance of the area this drainage is not affected.

The bottom line: using the plot dig one or several sloping trenches, combined into a single ditch in which excess water is discharged beyond the boundaries of the suburban area. This trench can be connected to natural receiving waters (river, ravine) or artificial storage of water.

The main question that arises when choosing the drainage system of the closed type — how to dig a trench while maintaining its functionality? This is usually done as follows: on the bottom of the trench is poured a layer of gravel about 15-20 cm, the voids that form small stones, out excess moisture. In order to avoid siltation of drainage sodden soil to the gravel layer of sand with thickness of 20-25 centimeters. Only after you put sand, you can dig the trench with soil.





There is another option of the drainage system gated — pipe system, buried in the ground at a certain depth; in the walls of the pipes bore the holes through which the pipe enters the water, and then it goes into the sewage system or into the drainage well.

A necessary condition for the successful functioning of the drainage system — consideration of all factors affecting the condition of the soil; for this purpose it is best to attract qualified specialists, through which your site will be landscaped, and topsoil is not disturbed. Although self-organization of the drainage system isn't complicated.
