fire water tank filling withen 8 hrs.
(OP)
Dear members,
i have an issue about a project that we have two fire tanks 2500 m3 each and as per AHJ requirements these tanks shall be filled withen 8 hours.
tie-in water from the municipality is 260 m3/hr.and feed pump with these flow values ( 260 m3/hr. ).
i suggest from the client to have fire truck to fill the tanks with the remaining water flow values, but he refuse this solution.
if you can help me to find another solutions, i will be very pleased.

To a ChE, the glass is always full - 1/2 air and 1/2 water.

Get the AHJ to relax its requirement and make it 8 hours per tank. Or
Increase the flow rate. Or.
Build a temporary tank of 2500 m3, fill it then pump at 260 plus the mains.
This is a totally artificial requirement so need challenging. It should make no difference how long it takes. That's why you have a tank.

Think you need to expand the question as to me it doesn't make any sense at the moment.

also the main problem happens during refilling of the tanks also.
RE: fire water tank filling withen 8 hrs.
The problem will be that during the tank filling, the local village / inhabitants will have no water. Tell him he will need to stand outside the gate and explain why...
Why are these tanks being re-filled?? sounds to me like they are being used for things other than fire fighting.... either that or you have a lot of fires?
You're not getting many sensible solutions here because your client is being an obstinate idiot. There's really not much any of us can do about that other than suggest you write him a report, keep copies and then leave and don't expect to work for that person again.

Filled when - for initial fill, during a fire situation, or to be refilled because the gardener over-watered the lawns?

My plan would be:
1) Request a dispensation from the AHJ for this requirement which is unreasonable and not based on any international code, standard or operating practice.
2) Build a spare tank of 2,500 m3 capacity which is not designated as fire water but "bulk water storage" or "utility water" and install a pump to fill at the required rate together with your utility supply
3) Request more water flow from your utility supplier on an infrequent basis
4) Go searching for your own water supply
5) Hire 50 large water tankers (25 m3) on the basis that you can do 2 trips and have a separate pump out system ( revise based on how many trucks you can turn round in 8 hours)
6) Shrug your shoulders and walk away

What is the output from the firepumps if on fire fighting duty?

I used to count sand. Now I don't count at all.

In your case since your permanent source of 260 m3/hr is not good to fill the connected tanks in 8 hours, you may use the fire tankers which is manual filling allowed by above referred code section.
See if this helps
