(54)	Sewage device for filtering excess fluid flows

(57) A device (1) for filtering excess fluid flows. The device comprises a vessel (2) and the vessel is provided with a floor (6), an inlet (8), a first outlet (10) and a second outlet (12), a solids removal means (28), a partition (14) and flow control means (20). The vessel 2 further includes two overflows (44,46). A first overflow (44) allows fluid to pass from an inlet side (16) to an outlet side (18) of the vessel. The second overflow (46) allows fluid to pass from the outlet side (18) to the inlet side (16). The two overflows (44,46) are arranged such that, during exceptionally high fluid flows or equipment failure, fluid entering the inlet side (16) may bypass the solids removal means (28) and overflow into the outlet side (18) via the first overflow (44). Fluid in the outlet side (18) of the vessel above a predetermined level overflows to the second outlet (12) via the second overflow (12).
