<p>The disclosure relates to a stormwater drain (1) with an openable grid (2). The stormwater drain (1) has a first filter (5) which treats the stormwater, and a sand trap (7) which collects solid pollutants. The sand trap (7) is connected to a channel (4) which is intended for emptying the sand trap (7). The stormwater drain (1) also has an outlet (8) for the treated stormwater. The filter (5) is disposed outside and around the channel (4) for realising a radial flow component in the stormwater through the filter (5). The channel (4) is substantially vertical and upwardly open so that emptying of the sand trap (7) may be put into effect when the grid (2) is open.</p> |
