A secondarily contained piping system has two spaced access chambers interconnected by a secondary containment pipe to provide a sealed housing for a flexible fluid supply pipe, the ends of which are disposed within the access chamber and have a connector element at each end forming a section adaptable to be interconnected to other fluid conduits, the diameter and bending radius of the fluid supply pipe and the size of the access chamber permitting the fluid pipe after uncoupling to readily be removed from the secondary containment pipe through one of the access chambers.

A secondarily contained piping system comprising: (a) a flexible inner supply pipe which is fitted at each end with a coupling, (b) an outer secondary containment pipe having a substantially larger diameter than the flexible inner supply pipe, (c) two spaced underground access chambers which are interconnected in a fluid tight manner through the side wall just above the chamber base, by the secondary containment pipe, (d) all flexible inner supply pipe couplings and associated fittings being disposed within the access chambers, (e) a fluid source providing an originating interface to the flexible inner supply pipe, (f) a fluid outlet providing a terminating interface to the flexible inner supply pipe, (g) access chambers are of sufficient size to permit manual or mechanical removal or replacement of the flexible inner supply pipe, ( h) the flexible inner supply pipe having sufficient bend radius to be removed and replaced through the access chambers, (i) all components of the system being chemically compatible with and impervious to the fluids to be transmitted and with the surrounding environment in which they are disposed, (j) the flexible inner supply pipe and its associated couplings and fitting being of sufficient strength to withstand internal fluid pressures, and (k) the access chambers and secondary containment pipe being of sufficient strength to withstand external loads.
