A pump attachment interface provides a fixed link between a first line in communication with a fluid reservoir, and a second line in communication with a mobile storage tank via a pump of a pump truck. The interface includes an interface body with a sloping surface that supports a fixed conduit such that a lower end of the conduit is at a height that is lower than an upper end of the conduit. The lower end is for coupling to the first line, and the second end is for coupling to the second line. The attachment interface also has a spill containment catch basin over which the second end of the conduit is located so as to catch any spillage from the second line when it is coupled to the conduit. The body can be a concrete block, or be molded plastic filled with sand or water.
