NYC Booster Pump vs. Fire Pump for Combination Standpipe Systems
NYC Booster Pump vs. Fire Pump for Combination Standpipe Systems
(OP)
I have the exact same situation that came up in a previous thread regarding combination manual-wet standpipe systems in NYC. http://www.eng-tips.com/viewthread.cfm?qid=279878
Basically, our building type requires a standpipe system based on floor area sizes (not a covered mall). It is a low-rise structure so manual-wet is the minimum requirement for the standpipe system. We are utilizing a combination sprinkler/standpipe system but require a pump to meet the sprinkler system demand only.
Since the pump is only required to meet the sprinkler system demand, we would like to call it a "sprinkler booster pump" in lieu of a "fire pump" so we can avoid the requirement for two separate water mains off two separate streets. However, there are questions as to whether or not a booster pump can technically feed into a combination sprinkler/standpipe system.
The only water supply requirement for a manual-wet standpipe system other than the FDC is a small connection for the purpose of keeping the pipe filled with water. Obviously, a booster pump will achieve this requirement and since the pump has a bypass, it will keep the standpipes filled even if the pump ever goes down.
Has anyone ever ran into this situation before in this jurisdiction? Can you have a combination manual-wet standpipe system supplied from a sprinkler booster pump with a single underground supply line in NYC? Or, will this "pump" need to meet all the "fire pump" requirements which includes two separate undergrounds from two separate streets?

It truly is a matter of semantics but it can have huge repercussions on the basic requirements for the system (i.e., two underground lines from two city streets). In any other jurisdiction, a pump serving a fire system is a "fire pump" but that is not the case in NYC; for whatever reason the differentiate between a booster pump & fire pump.
I was hoping that someone with experience in NYC would be able to answer whether or not a "sprinkler booster pump" could supply a combination manual-wet standpipe system or not.

I learned, and still say, A "Booster Pump" connects to a city supply.
A "Fire Pump" is fed from a tank.
Guess NYC has different meaning..
