A drainage system is a complex, which includes pipes and the design of their fastening, designed to accumulate water in them and to drain it through them into the internal sewerage of a building or house, or to special catchment areas. This is the main function of the catchment, the essence of which is to prevent water from falling on the facade and basement, lawn, water ingress into which it can destroy structures, thereby causing a decrease in the service life of the entire building.

Types of drainage system
one. Internal drainage system – designed for the northern parts of the country, where water freezes on open drains;
2. The external drainage system is divided into two types:
– an unorganized system, which is designed for small structures with a shed roof, that is, an organized drainage system is not required, the accumulation of water on the roof flows down it directly to the ground and then into the sewer. To prevent water from eroding the foundation of the house, the roof is taken out about one meter beyond the perimeter of the building;
– organized system – consists of gutters that collect water, from which it flows from the roof, as well as pipes through which water flows further into the sewer.
MATERIAL FOR CONSTRUCTION OF THE DRAINAGE SYSTEM
There are three main materials on the modern market: steel; PVC; copper.
The gutter system made of galvanized steel has many advantages, such as:
– High strength – to withstand heavy loads, in heavy rain, ice formation or wet snow;
– Protection against corrosion and other negative environments thanks to its plastisol polymer coating;
– The material is fireproof;
– The material has a smooth surface, which improves the sliding of water and prevents pipes from clogging.
– Longevity of the material, approximately seven to fifteen years.
Gutter system made of plastic – in the modern world is the most popular material for drainage systems, and indeed for many other products.
Pros:
– plastic is not susceptible to corrosion and alkali;
– confidently withstands temperature extremes;
– has a wide range of shapes and shades;
– smooth material, which allows you to stop the clogging of the system;
– service life from fifteen to twenty-five years.
The disadvantage of such a system is that if installed incorrectly, it may not withstand a large load.
A copper gutter system is a material with many advantages, for example:
– strength;
– attractive;
– service life reaches up to one hundred and fifty years or more.

Minus – very expensive material.
