    Abstract: An oil spillage recovery arrangement characterized by a chamber or housing having a receptacle which receives a mixture of oil and water from a body of water, a siphoning conduit disposed within the receptacle for separating the oil from the water (where the latter passes outside of the receptacle and into the housing or chamber), and one or more other receptacles for receiving the recovered oil. Provision is made for the selective pumping of the accumulating water from the housing or chamber back into the body of water where the recovery arrangement is maintained, as, for example, a flowing stream.
