Storage for fire flow in a well tank
Storage for fire flow in a well tank
(OP)
I am completing the design of a well house on a project that originally had been designed without fire flow considerations. The previous design called for a 5000 gal tank. Where can I find, or can anyone tell me, what the storage requirement for fire flow demand is?

how did you arrive at that 50% figure while at the same time coming up with 2.5 hours? Just curious.....

I don't have the index with me but the web site is www.nfpa.org
Storage requirements will obviously depend on fire flow requirements. I built two reservoirs at two different airports in the past couple of years that maintained 30 minutes fire flow capacity. (Same client, same risk engineer and virtually same design).
Again see the NFPA for guidance. They will most likely be referenced in the local building codes but check them as well in case they have a stricter requirement.

1. contact the local F.D. and ask them what thay need for fire flow. (ie: 1500 GPM for 2 Hrs = 180,000 Gal.)
2. add the system peek demand to this.
3. if the system will not use enough water to keep the water from stagnating, add a recurculating pump that pulls the water from the bottom of the tank and dumps it back in on the otherside in to the top of the tank. and if necessary add a disinfection booster to this line have it set up with a timer so the operator can adjust the amount of disinfectant that is added.
