Onsite Private Fire Water System Question

[raydefan]

I am a civil engineer working on an onsite private fire water system for a hotel/resort site. My experience with fire water systems only includes off site systems which would include public fire hydrants and connection lines for a building’s sprinkler system, so I am trying to design this “without looking too stupid” to the fire departement plan checker or my Client. I have spoken to the fire department and they recommended:

“4 way automatic wet standpipes from an onsite private fire main” for the protection of the pool area. Does anyone know of a manufacturer of these types of standpipes or a detail I could use on my plans? What is the typical spacing of these standpipes? Do I assume 300’, which is typical for a fire hydrant?

The fire department also recommended an “automatic wet standpipe in the parking garage connected to a private onsite fire main” to protect a little paseo area next to the parking garage. Is this connected to the building somehow and if so, would I just provide a connection 5’ form the building and the standpipe would be shown on the mechanical plumbing plans?

Any help would be appreciated.

This doesn't sound like civil engineering work to me. Rather than try to glean enough information to try to cobble together what it needed, from one of these knowledgable and qulaified individuals that watch this forum, you should buck up and hire someone qualified to do this for you.

I have no idea what a "4 way automatic wet standpipes" is. If you have automatic standpipes, you are looking at providing 100 psi at 250 gpm at each hose valve. Do you have this kind of pressure?

I have to agree with the other poster. This may need to be looked at by an FPE or someone with similar experience.

Good luck!

Thanks for the responses. Here is the bottom line. There is a pool area in the middle of this hotel that needs fire protection. It is too far away to be protected by the public offsite fire hydrants. What is typically used in this scenario?

sounds like they want 2 1/2 stanpipe connections in the pool area so they can bring hoses in and hook up. or some call it a wall hydrant

does sound like you need a sprinkler designer for your questions

but it does sound like you need someone experienced with the hydraulics, b/c depending on water flow test information and distance from public water supply

is the hotel already need a fire pump

but this is something that really will need P.E. experience in this area... ....you have a ton of potential mistakes that could happen if you just "piece this together"

go hire someone..

the "potential savings" are not worth the potential extra cost
