Abstract: An additional containment system for a fluid containment vessel includes an outer section, an inner section, and a monitoring system. A plurality of independent and distinct zones of interstitial space are positioned between the outer section and the inner section. The monitoring system is connected to and separately monitors a pressure in each of the zones. A divider plate is attached to both the inner section and the outer section and divides a first zone from a second zone. Upon detecting a leak, the monitoring system provides an indication as to the leak being in the outer section or in the inner section, and upon detecting a leak, the monitoring system also provides an indication as to which of the zones the leak is detected.

Abstract: A lining system for a fluid containment vessel having an outer section with a floor surface and a vertical surface. The inner section is attached to the outer section so that interstitial space exists between the outer section and the inner section and a continuous negative pressure exists in the interstitial space. The floor surface is formed from a cost saving template. The vessel is divided into at least two independently sealed portions. The inner section includes a shell skirt that reaches a critical height within the vessel to reduce the effects of corrosion and to avoid stresses on the vertical surface. A flushing mechanism allows the area to be purged of any leaked material.
