A system for containing and detecting the leakage of liquid from a receiver, such as a tank or conduit, includes absorbent material which is capable of absorbing liquid which leaks from the receiver. The absorbent material is enclosed by casing material which is dissolvable by the liquid in the receiver. Upon the occurrence of a leak, the liquid which leaks from the receiver dissolves the casing material to expose the absorbent material so that it can absorb the leaking liquid. A detector provides an output signal in response to leakage of liquid from the receiver. The detector may include a pair of electrodes which are electrically insulated from each other by material which is also dissolved by liquid which leaks from the receiver. When the insulating material between the electrodes is dissolved, current is conducted between the electrodes to provide the output signal. The absorbent material may be disposed in a plurality of separate containers formed of the casing material which dissolves when exposed to the liquid in the receiver or may be positioned as a unitary body beneath the receiver.
