<p>A surface water conduit (4) is arranged to utilise the gravity for transport of surface water to an outlet (6) in an arrangement in a surface water system with at least one surface water conduit (4) and a plurality of surface water receiving units (1) arranged to discharge surface water into the surface water conduit in places along the same at different distances from the outlet located at a downstream end (5) of the surface water conduit. The arrangement has means (7) arranged to form flow resistance upstream in the system at a considerable distance from said outlet in order to thereby increase the level of the surface water in the system flowing towards the outlet upstream of itself.</p> |
