These are buried in the ground with different extent of permeability to collect and expel the water in excess. This system avoids to set a special form of the ground surface. Drainage is essential for grounds where water infiltrations can produce heavy damage both in agriculture and in civil engineering projects. To build a correct drainage network it is necessary to identify the underground water infiltrations. Often it is necessary make a survey of the surface and underground hydrology also with help of meteorological, hydrometrical and phreatical data. Moreover it is very important to know the physical and chemical characteristic of the ground, fist of all the permeability coefficient and the depth of the first impermeable layer.
