An improved system for containment and detection of leakage of petroleum products from subterranean tanks or lines is disclosed wherein the tanks or lines are provided with a leak sensing means positioned adjacent the tank, and the tank or line together with the leak sensor is enclosed in an impervious enclosure which is sealed about the tank or line to prevent actuation of the leak sensor except due to leakage from the tank. In a preferred form the leak sensor is housed in a perforated duct which extends through and is sealed within the enclosure permit...
