Fire Suppression Tanks

A rural, mental health, critical-care facility, required replacement of two pressure vessels storing water for the facility’s sprinkler system.  The existing tanks were located approximately 20’ below grade and access to them was via a second floor basement room.  The new tanks could not be located in the same area.  Most significant, was the need for the working end of the tanks to be accessible without requiring confined space entry.  The solution was to locate the tanks below grade by cutting into a nearby embankment and pouring a concrete retaining wall around the operating ends of the tanks.  The project was completed by constructing a grade level accessible building around the working ends.  Additional requirements included designing a compressed air system capable of keeping the tanks at sufficient pressure to meet the water delivery requirements for the sprinkler system.
