Forum: I am working on a project where, due to space constraints, we are looking at using a vertical turbine fire pump. The pump would be fed from a concrete tank set underground and filled by the local water service (project is overseas). When looking through NFPA 20, chapter 7, I am trying to determine the requirements for submergence. In doing so, I think I need to follow the Wet Pit requirements (second impeller from the bottom of the pump bowl assembly below the lowest pumping level). However, this installation does not meet the strict definition of a wet pit. It is also not a well. Not sure how to approach this.
Also, I am a bit confused as to what the lowest pumping water level means. Is this the lowest starting level of the water, or the lowest point to which the pump should pump to? This is becoming an issue as the architects are trying to put final touches on the size and depth of the tank. This is the first vertical turbine pump I have ever been involved with and it is definitely throwing me a few curve balls. Any help in clarifying this is greatly appreciated.
