Abstract: A hydraulic separation and collection system applicable to linear street curb-inlet type drainage-chambers, independent or connected to a storm drainage network. The FIRST FLUSH COLLECTOR™ is a pollutant separation and collection apparatus that can be integrated into an existing storm drain network, or be retrofitted as a component into a new or existing curb-inlet type drainage-chamber. The outfall from the FIRST FLUSH COLLECTOR™ can be redirected to a conventional stormwater pollutant BMP, or be diverted to a sanitary sewer, storm drain, or combined collection system for treatment downstream. The apparatus is envisaged as a simple, easy to install prefabricated-kit utilizing a basic build-in-place separation and collection apparatus. The apparatus can be readily adapted to the needs of a given curb-inlet type drainage-chamber with minor alterations to the chambers, or to the connected existing storm drainage network.
