Fire Flows For Fire Hydrants
Fire Flows For Fire Hydrants
(OP)
I am involved in a project for a correctional facility located outside the city limits. The facility has a fire pump to provide water for their sprinkler system and a separate diesel fire pump taking water from the river to supply only fire hydrants. The exisiting hydrant pump was installed in the 1970's. Their are approx. 12 hydrants on the fire loop around the property. There are numerous buildings spaced out across the propery. The client is looking at replacing the the existing diesel fire pump with a new one. The existing diesel pump is rated at 6000 gpm. This seems quite large to me, but I have never desinged a hyrant system before (usually civil engineers take care of the under ground water distribution systems).
Does anyone know which code would provide you with the information regarding designing for fire hydrants? NFPA? Other (i.e. fire flow calculations)?
Thanks

RE: Fire Flows For Fire Hydrants
NFPA 24 provides information for fire hydrants. You will need to determine the occupancy and hazard for each individual building to determine the actual flow requirements for the various yard hydrants. Using a combination of NFPA 13 & NFPA 24 will more than likely provide the guidance you need. I would suggest some serious questions before I replaced a 6,000 gpm fire pump with a 500-1,000 gpm fire pump.
RE: Fire Flows For Fire Hydrants
If this is a large multi building facility and just this one pump provides the fireflow, then 6000-gpm may not be out of line.
Just my 2 cents

Just check the table and follow the notes. That should get you going in the right direction.
