Abstract

The oil is separated from the rainwater that runs off a parking lot or off the pavement of a filling station. An inlet tank (12) receives the runoff water. When the water is entering that tank at a very low rate, the surface water and/or oil in the inlet tank drains to a main separation tank (21) where the oil floats on clean water. That clean water is fed to an outlet conduit (l8) that feeds unpolluted water to the city sewer or to a river. When the inlet flow increases to an intermediate rate, a pipe of inverted L-shape (14) feeds clean water from the inlet tank (12) to the outlet conduit (18). When the inlet fluid has a very large flow rate, as might occur during a heavy downpour of rain, the fluid level in the inlet tank (12) rises to a level at which there is a direct overflow into the outlet conduit (18).
