Abstract
A system for the storage and dispensing of liquid product from an underground installation comprises a storage tank which bears on its top a containment chamber enclosing all fittings for apparatus which gasoline or other stored product will pass through under pressure. Attached to at least one fitting each are a fill arrangement for introducing liquid to the storage tank, and a pump for pumping fluid therefrom, both of which are entirely enclosed in secondary containment, the storage tank itself and piping also being enclosed in secondary containment, such that the system is pressure tight, and recovers all leaked fluid in a state in which the fluid can be reused.
