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. The uniquely adaptative capability of the apparatus enables selective structuring based on the
retrofitting requirements of a curb-inlet type drainage-chamber. The
system is designed to
handle a variety of
ecosystem-contaminants,
ranging from basic street-refuse and floatable objects, to coarse
sediment, finer
silt, and comparatively minute environmentally-hazardous petrochemicals, heavy-metals, phosphates, and nitrates. The
system is design to refuse floatables and debris which will continue to the existing curb-inlet type drainage-chamber. Other pollutants contained in the
first flush are readily collected from the apparatus and transferred to a selected
outfall facility. The
system has no moving or
mechanical components and is designed to function on fluid hydraulic principles.
