The invention relates to a system of draining, filtering, transporting and purifying waste water. According to the invention, a decanter (fig. 1) is disposed in the lower part of a gutter in order to collect rain water falling on the roof. The filtered rain water is drained through a perforated part into numerous containers (fig. 3) which are filled with overflow water by means of tubes (12 12), before entering a manifold (fig. 11). The aforementioned manifold (fig. 6) terminates inside a funnel (fig. 7) comprising a shaft (33), which is used to divert the water into each of the upper orifices (1-1) of two decanters (fig. 1 ). The filtered water is then released through the perforated part (5) into the first leak-tight container in the chain of buckets (fig. 9) which transport the water and purify same by means of decantation.
