We have a project with a limited water supply that makes it impossible to automatically replace the required fire water in 8-hours.
Could a larger (1.5 x the required fire flow) water storage tank be an option? Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

We have gotten by with a water truck being the means to refill the tank in 8 hours.

We were able to get a variance approved in a similar situation. We supplied a second tank, of same size, as a back-up. We looked at getting the water trucked in but there were still issues with availability for that option also. Ultimately a second water storage tank became the most feasible option. I would think your proposed larger tank would basically be the same thing.

It is the call from the AHJ. We have used larger tanks or secondary smaller back up tanks to provide supplemental water to prevent total tank depletion and allow refill within NFPA 22 req's. In rural areas AHJ's have stated they will use their water supply trucks as a refill tank aiding the refill within 8 hours. Both the owner and the fire department will need to be involved in understanding the water refill rate and it must be well documented.

Most AHJs would require a second tank if there is room for it. Leave a Reply. |
