Abstract of the Disclosure The invention relates to a draining arrangement for removing water from roofs or equivalent areas. The aim of the arrangement is to improve the draining effect making it possible to use smaller draining pipes, and further to avoid disturbing noise in the pipes. The arrangement is mainly characterized therein that the opening (4) of the vertical water pipe (3) is situated directly at the surface (1) of the roof and is covered by a lidelement (5). This lid is situated at such a height (hc) over the roof that a certain beforehand defined amount of water can flow under the lid where the water stream on its way to the opening of the vertical draining pipe and without changing its direction, continuously changes to closed flow simul- taneously as the air entrance becomes closed.
