A sump assembly (11) for collecting and discharging spilt fluids from a floor surface (16) in a processing plant. The sump assembly (11) comprises a casing (13) which is adapted to be received in a cavity (22) in a floor structure (20), a pump (15) received and supported in the casing (13), a gap between the casing (13) and the pump (15) to allow fluid to enter the casing (13). The sump assembly (11) also comprises a first filter (17) located equal to or below the top of the casing (13) and extending across the gap between the inner wall (29) of the casing (13) and the pump (15), and a second filter (19) located below the first filter (17). In use, the fluid enters the sump assembly (11) through the gap and passes successively through the first and second filters (17, 19) into the lower regions of the casing (13), before being discharged from the casing (13) by the pump (15).
