Sprinklers to mitigate for fire access - tank and pump set up

Definitely different rules, as per my other comments to you, we are 120m from the mains, uphill and the water company and BC are happy with 32mm mains water.

But, I do know that you have issues with water pressure currently.

Is there any way that you can get mains and then 'boost' it somehow for the sprinkler.

 

Sorry for jumping on an old thread but appear to have a very similar issue to what you experience.  My build is in the countryside and the closest a fire appliance (truck) can get is 120 metres away (I have a narrow lane of about 2.3 metres leading from the road to the site, which I only have access across as opposed to ownership, and therefore unable to improve/widen access). 

 

I contacted a fire engineer asking about sprinklers and received the following response: The only solution I am aware of for these circumstances (subject to the house having no floor greater than 4.5m above ground) is for a sprinkler system to be installed and all points of the inside of the building to be within 90m of where a fire appliance can get to.  The distance is reduced if the house has a floor greater than 4.5m above ground, then the acceptable distance is 75m.  Wherever the fire appliance gets to, it should also not be further than 20m from the 'main road' junction with your track.

 

My take from this is that because I'm more than 90 metres away, a sprinklered solution won't work?  Your comment suggests otherwise though? I'm also in Somerset so keen to hear a little more about your experience!

Have you proposed a big tank that the fire brigade could use?. 10m3 is the size  they like I think.

Then there is no reliance on the sprinkler working, power still working etc. You'll need a turning space too.

I spoke to the fire engineer again with a few more ideas (installing a horizontal dry riser type system, installing a big tank etc and his response is that because its outside of the regs, I won't get it approved, and that i started building at my own risk.  Getting very nervous now
