Spills from an oil well are caught in a basin surrounding the oil well casing. The basin is drained from the bottom through a conduit connected to a tank. A vacuum is applied to the tank by a suction pump. The control for starting and stopping the suction pump is by a control which is located above the basin. The control is manually operated by a man who works on a grating above the basin and may see into the basin.
