A remotely monitored and controlled secondary containment system for underground storage tanks. Contamination of the soil and ground water in populated communities by gasoline and other petroleum products leaking from corroded underground iron or steel storage tanks has risen to an alarming level. This invention provides an efficient, and economically built and easily installed means for cleanup and for in-place decontamination of leaked or spilled hazardous liquids from the tank environment and for the repair of the leaking tank, without excavating the tank.
