20150268667 | Method of Configuring a Vortex Flow Control Device and a Vortex Flow Control Device - A method of configuring a vortex flow control device | 09-24-2015 |
20140001106 | Treatment Device | 01-02-2014 |
20130001144 | Water Treatment Apparatus - A water treatment apparatus comprises a chamber divided by a partition into a treatment section and an outlet section. The treatment section may, for example, contain a filter media including organic material which supports a shrub or tree. Runoff water enters the treatment section over an inlet chamber which forms a bridge over the outlet section. During heavy flow conditions, some of the incoming water overflows inlet bypass weirs to pass directly to the outflow section, bypassing the filter media in the treatment section. | 01-03-2013 |
20120261012 | Flow Regulating Device - A flow regulating device | 10-18-2012 |
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 |
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 |
