The construction of the drainage system begins with the fact that the side of the section is determined, if the site is located on a relatively flat surface and the slope cannot be determined, then trenches with an inclination in one certain side should be dug up. The ditches are dug around the perimeter of the entire site, and they should converge in the same place in the site — a large ditch (in shape this system resembles a “Christmas tree”). The slope of the trenches should be an average of 4 cm. To check the correctness of the construction of the trenches, you can let water over them, if it stagnates in any place, then the level of inclination must be changed. In your free time you can buy stones for a bathhouse.
