It’s my understanding that the AHJ was aware the water supply in the area was not good but there was never a discussion of a water tank during any of the pre-development meetings. I will reach out to him again and let him know it looks like that’s where were headed….

Was tank a topic at pre-development meeting? Best.

I’m guessing not. If not then you don’t need the hose allowance (since there’s no place for hoses to be used). <image07cf41.JPG><http://www.SummitCoUS.com> Mark Sornsin Sr. Fire Protection Engineer Direct: 701-499-1391 Cell: 701-526-8585 From: Sprinklerforum [mailto:[email protected]] On Behalf Of Travis Mack Sent: Wednesday, March 20, 2019 8:57 AM To: [email protected]<mailto:[email protected]> Subject: Re: Water Tank If you have hydrants downstream of the tank, do you need to account for site fire flow requirements?

Worst case for this particular building would be OH-2. (.2/1500 = 300gpm + 250 hose. 550gpm for a minimum of 60 minutes = 33,000 gallons). Per NFPA22 (2013) 5.1.3.1 round it up to 40,000 gallons. Does that sound about right? Brian Harris, CET BVS Systems Inc.
