The present invention may include a separation tank with an outer chamber and
an inner chamber positioned within the outer chamber. An inlet and an outlet may
be in communication with the outer chamber. A first opening may provide access
between the inner chamber and the outer chamber. An inlet channel may extend between
the inlet to a second opening in the inner chamber. A plurality of lower baffles
positioned between the outer chamber and the inner chamber and adjacent to the
first opening may be included. A plurality of upper baffles positioned between
the outer chamber and the inner chamber and adjacent to the outlet may be included.
Floating and non-floating particulate matter may be trapped in the separation tank
as storm water flows through the apparatus.
