The installation of drainage systems is one of the components of works on the improvement of the site. In some cases this is a very important component. Even if the owner did not plan large-scale works to drain the territory, at least superficial drainage ditches, blinds and gutters are still being arranged.

The causes of flooding of the site and the basic principles of surface water drainage are very important factors. In this article we want to discuss in more detail the methods removal of excess water on the site and decorative possibilities for the design of devices for the removal of moisture. After all, water on the site is not only a natural disaster. It is also a huge opportunity and an excellent tool for the landscape designer.
Project of drainage system
The design of the water disposal system is an important stage in the improvement of the site. If there is a danger of flooding with high groundwater or the soil is weakly permeable to water, the drainage of the excavation during the construction of the house is mandatory. It is better to find out the need for this in advance, so as not to face the problem after the erection of the house is finished. Drainage structures, therefore, are called a system that underground drainage and blind area , downpipes and surface grooves , even a pond- all this is a single complex, the artificial recreation on a small stretch of the natural cycle of water in nature.
Falling with rain, moisture is partially absorbed by the soil, partly drains into reservoirs along natural slopes. The water that has been infiltrated into the soil becomes ground and, along the slopes of the waterproof layers, flows down towards the reservoirs located in the lowlands.
Installing a drainage system
When you are going to make a drainage system, you need to try to recreate the natural conditions of water in nature using artificial devices. It is highly desirable to calculate the system so that it works as independently as possible, without using coercion in the form of drainage pumps. It is necessary to try to think over the design of water disposal so that there was no need to force the water to move to where it does not flow. The principle of the drainage system should be based on self-dispersion: surface water is collected in ditches and let it flow away from the site; weakly permeable for moisture clay soil with the help of drains and drainage cushions making it easy to absorb water.
So, drainage ditches and trays mimic rivers, underground drains – current groundwater, places of collection of allotted water – lakes and the sea: everything is like in nature. Then the functioning of the drainage system will be the most reliable, independent of interruptions with electricity. And such a system will be easier to fit into the landscape. Planning drainage, it is necessary to take into account the level of groundwater, natural slopes of the relief, the depth of the foundation, the location of buildings and tall trees on the site.
Since the main water load falls on a warm season, it is not necessary in all cases to break below the depth of freezing to drain water. The surface water drainage is quite effective, especially if the site is located on a small slope.
