20100300568 | Vortex Flow Control Device - A vortex flow control device is manufactured by forming a template unit having end walls of which the wall has an outlet opening, and a partial outer wall. The partial outer wall has an opening. A plate is subsequently secured to the template unit to partially close the opening, to leave an inlet. The size of the plate is selected so as to result in an inlet | 12-02-2010 |
20110127204 | Stormwater Gully - A stormwater gully comprises a chamber in which an outlet assembly is installed. The outlet assembly comprises filter units connected to an outlet housing. In use, stormwater can flow from the chamber in an upwards direction through filter units into the outlet housing. The outlet housing has an outlet, which extends from the gully. At high rates of flow, the water level in the chamber will rise until water can flow into the outlet housing through bypass inlets. The bypass inlets are connected to the interior of the housing by siphons defined by arched regions of a top cover. The siphons allow rapid discharge of water until the water level returns below the level of the bypass inlets. A slow drain down feature is provided which enables the chamber and outlet assembly to be drained below the level of the primary inlet. | 06-02-2011 |

20120292235 | Treatment Device - A treatment device for stormwater is provided that comprises a container which in use contains a growing medium and a hydrodynamic separator located within the container. The hydrodynamic separator comprises a separation chamber, an inlet duct extending from the outside of the container to the separation chamber, a solids outlet; and a liquid outlet that opens into the container. In use, liquid flow containing solids enters the separation chamber through the inlet duct and is caused to swirl within the separation chamber, thereby causing solids to exit the separation chamber through the solids outlet and liquid to exit the separation chamber through the liquid outlet and to flow into the growing medium. | 11-22-2012 |
