How to make a drainage drain in the country, if the site is lower than the rest?

Good afternoon, Eugene.

A lot of unknowns in the matter. Embossed slope? Or have all the plots raised the ground except you? How much lower is the plot? If you are in the pit, then you must also raise your level. By importing soil and subsequent laying of the drainage system.

It seems to me that, nevertheless, a high level of groundwater is a natural bias - a schematic drawing for clarity. It is designed based on many factors: the existing landscape, the type of soil, the location of the gutter relative to the sides and the elevation of the site.

There are a number of rules that ensure the effectiveness of the drainage system:

1. Excavation work is underway on the construction of trenches and pits. The slope of the trenches is applied equal to 10 mm. on 1 meter.
2. At the bottom of the dug trench with an appropriate slope, a sand cushion 2-4 cm thick is arranged. Then the geotextile is spread and crushed stone is poured with a fraction of 20-40 mm., The layer thickness is about 10 cm. And only then a drainage pipe is laid, which is sprinkled with crushed stone with each side in the same layer. After it is covered with geotextile overlapping and covered with clean sand. Sand is used in the pillow and backfill as an additional filter. In combination with geotextile, the risk of siltation and clogging of the drainage holes of the pipe is minimized. Crushed stone creates the necessary rigidity to keep the pipe intact. Figure 1 shows a sectional view.
3. Viewing wells are arranged every 36 meters of a straight section or when the drainage pipe is turned. This is done to flush the area in case of siltation. It is important to pay attention: in the inspection wells, the pipes are broken, and not just a hole is made. It is clearly demonstrated in Figure 2.
4. Drainage threads are reduced to one drainage filtration well from where water enters the collector well.In your case, since the area is lower, you will need to install a drainage pump, which, when filling the collector, will pump water into the ditch.

Please note that roof drainage is carried out in separate pipes. In no case does storm drainage connect to the drainage system - this is a common mistake of many builders.

Simple at first glance, the drainage system includes many nuances. The cost of work and materials entail significant costs, so I advise you to entrust the work to professionals.
